APTUS Nutrients Dazzle Aussie Growers With Dank Yields

FIRE BUDS: APTUS Plant Tech Nutrients Making Shockwaves ‘Down Under’

APTUS Plant Tech Nutrients Australia

The mass-importation of APTUS Plant Tech Nutrients to Australian markets has changed the game; leading (in part) to a renaissance of fresh, high-quality produce available locally. In this way, Aussie-grown cannabis is no exception.

If you’re wondering why APTUS Plant Tech Nutrients have supposedly made such a massive impact… well, there are a few keys to their success. APTUS have recognised the significance of public education; they are determined to patch up the gaps in understanding that exist, to improve outcomes for all growers. The knowledge of precisely how nutrients act upon plants isn’t as common as it could be. Many misconceptions have circulated around our continent… so, APTUS have teamed up with us to set the record straight.

Who Are APTUS?

APTUS are a biostimulants company. They are the market leaders in Europe, and have been for well over a decade. The company has also managed to become a staple of the American market – in less than 10 years.

APTUS Plant Tech Nutrients have been adopted by some of the most prominent and successful licensed cannabis growers across North America, Canada and Europe. The APTUS team (in partnership with licensed producers overseas) have won many awards, in competitions such as The Cannabis Cup, Chalice Cup, HighTimes Cup, and Secret Sesh.

What Makes APTUS Plant Tech Different?

APTUS Nutrients have been designed for plant development; optimising bioavailability and transport of essential nutrients.

The APTUS range is the most targeted and specific biostimulant range on the market; with a combination of standalone products and boosters, each requiring precise measurement and usage (get yourself a syringe!).
APTUS does their very best to educate and inform their consumers, well above and beyond providing a high-quality product. This is what sets them apart from other plant nutrients companies.

For many growers, the question of how their plant assimilates nutrients is still a total mystery to them. The metabolic absorption of nutrients by the plant, the bioavailability of nutrients in the soil, along with the interactions between different kinds of nutrients, are all foundational steps to attaining success as a gardener or grower.

Applying Nutrients in Harmony With Your Plant/Medium

Many modern plant nutrition systems are managed akin to a controlled chemistry experiment. All kinds of compounds are released into the plant’s environment; for nutrition (ie. Nitrogen, Phosphorus, and Potassium salts) or protection (pesticides, fungicides and insecticides).

So long as you ‘pull it off’, the end result is ultimately predictable; with thanks to precise measurement and control of added compounds.
Sounds good, right? Well, there are issues that commonly emerge with such precise methods. Typically, as more additives are introduced into the growing environment, the plant is placed under compounding pressures.

APTUS Plant Tech Nutrients

Recently, we’ve seen droves of westernised cannabis growers – so used to their indoor labs and scientific grow ops – taking a slightly different approach. Turns out, cannabis as an organism grows best when its conditions are balanced.

The addition of pesticides and chemical nutrients as ‘curatives’ typically creates various imbalances in the nutrition uptake of the plant. It’s clear that, for natural organisms, the use of chemical-based nutrients and pesticides does not ultimately satisfy their conditional needs… sometimes, it even creates serious deficiencies.

If that wasn’t bad enough, chemical fertilisers tend to acidify the pH of growing environments. This opens up a host of vulnerabilities for pests and fungal diseases to take advantage of. Chemical fertilisers and pesticides are both known to decrease microbial life; significantly reducing species and populations living in your grow medium. This results in a poor-quality medium, with poor mineralisation and minimal plant stimulation.

The only way to fix these problems is to introduce optimal nutrient uptake sequencing; requiring a broad understanding of nutrient interactions, and a knowledge of nutrients and their bioavailability.

Ultimately, when it comes to plant development, a ‘preventative’ approach is best.

Stages of Plant Development

Plants undergo distinct stages of development. In the case of cannabis, the primary stages are rooting, vegetating, and flowering.

These can be broken into more specific stages: rooting, growing, shooting, blooming, fruiting/flower development and maturation. Each stage requires its own specific balance of nutrition and mineral uptake, for maximum productive output.

Every plant is slightly different; the nutritional needs of a leafy green plant (like spinach) will differ to that of an apple tree. There is no ‘silver bullet’.

Timing and Sequencing Your Feed

A rookie error is to supplement your specimen with growth ‘boosters’ at the wrong stage of development.

For instance, many growers add a Phosphorus and Potassium (P/K) booster during all or most of the bloom phase.

This can create significant problems with nutrient uptake; decreasing yield and quality. Most plants only need small amounts of Potassium during growth and early bloom. Potassium is mostly needed during the ripening and maturation stages, or ‘late bloom’.

Excess Potassium in the growing medium can ‘push’ away Nitrogen, Calcium, and Magnesium – some of the most common nutrient deficiencies. If the plant cannot utilise the nutrients you feed it, the minerals will be left unused, precipitating in the growing medium.

Leftover nutrients will interact with micro-life and other minerals; causing nasty imbalances, absorption problems and medium deficiencies. This can cause what’s known as ‘nutrient lockout’.

Growers can avoid nutrient lockout by respecting the natural organism and providing the right balance of nutrients at the proper development stage.

Nutrient Antagonisms and ‘Nutrient Lockout’

Understanding how nutrients react to each other is essential. Without being aware of these interactions, you may over-supplement with a specific nutrient, in an attempt to correct a deficiency.

Not all deficiencies are caused by a lack of nutrients!
Most nutrients work together beneficially, but this is not always the case.

For example, a Calcium deficiency may be diagnosed due to low Calcium levels… or, because of high levels of Nitrates (NO3). Nitrates can block Calcium absorption.

To amend this, use Organic Nitrogen instead of Inorganic Nitrogen. Many modern synthetic fertilisers primarily contain Nitrates, or other salt-based forms of nitrogen. Fertiliser Salts are the most common cause of tip burn, nutrient antagonism, and weak plant growth.

Antagonisms between certain nutrients reveal how overdoses of one element can lock out or displace other elements. If Phosphorus is found in excess, it brings in more Nitrogen to the plant, creating an imbalance in nutrition. At the same time, Phosohorus also limits Zinc, Iron and Copper.

As we know, optimum nutrition is achieved by maintaining balance within the nutrients in the medium. Understanding the antagonistic actions of nutrients helps to more accurately diagnose problems and re-establish equilibrium in your medium.

Such nutrient imbalances often arise when growers attempt to create their own ‘custom’ nutrient recipe… usually from multiple product lines and companies. Unless this grower knows their stuff, the likely result is a nutrient overdose and plant rot.

Nutrient lockout results in decreased yield and quality. In contrast… if you use a balanced, high-quality, specifically formulated nutrition system, your plants will maximise upon their full genetic potential.

The Biochemical Sequencing of Plants

Plants have a defined biological sequence of nutrient uptake.

If you break the beginning of the sequence, the rest of the plant’s development becomes ‘broken’ and uneven.Get the beginning right, and the rest falls into place.
The biochemical sequence starts with Boron (B); which moves sugars throughout the plant, particularly at the sites of new growth. It’s in these new growth sites, within the root zone, that the plant leeches sugars into the medium.
These sugars feed microbes; which, with the help of weathering, transform Silicates (Si) into bioavailable Silicic Acid, through a process called ‘silicification’. In turn, Silicic Acid adjusts the plants’ intake of essential nutrients such as Calcium (Ca), Nitrogen (N), Magnesium (Mg), Phosphorus (P), and Potassium (K).

The Biochemical Sequence is What Makes Calcium Deficiencies so Catastrophic for Plants

Calcium deficiency is an extremely common problem in growing.

Calcium interacts with many other minerals commonly used in fertiliser regimens. Antagonism towards Calcium is a common feature of mediums with excess Nitrogen, Potassium, and Ammonium-based compounds.

If Calcium uptake is limited in any way, the uptake and availability of all other nutrients will be impacted. One of the best ways to increase Calcium availability and uptake (other than chelating with amino acids) is to optimise Silica levels in the form of Silicic Acid.

Silicon: Not Discussed In Modern Agriculture

Silicic Acid is a naturally occurring compound found in healthy soil environments. While Silicon is the second most abundant mineral in the earth’s crust, it is not readily absorbed into biological tissues in its common forms (potassium silicate, calcium silicate, silica, etc.). Silicon is often found in larger molecules that cannot penetrate cell walls.

Silicon is responsible for increasing dry weight, strengthening plant tissue, balancing and increasing nutritional uptake/assimilation, immunity, and resistance to all forms of biotic and abiotic stress.

With these kinds of benefits, it is critical for growers of all kinds to appreciate the power of Silicic Acid.

Silicon: The Nutrient Transport System

Silicic Acid has a remarkable effect on the uptake of other nutrients. Think of it as a train engine, helping to pull other ‘cars’ throughout the plant sap. Silicic Acid is particularly good at increasing the transport of heavy, immobile minerals – like Calcium.

Plants don’t have muscles, in the same way we do. Instead, elements move around the plant, themselves. Suction, pressures, and molecular interactions guide the entire process. Lower pressure conditions induced by synthetic fertilisers and over-watering make the heavier molecules less mobile. If you increase the pressure, minerals are more easily carried throughout the plant.

Silicic Acid is a ‘sticky’ fluid molecule. When present, the pressure of the vascular system (like our circulatory system) increases. Imagine a hose filled with tiny particles of sand (nutrients). If a trickle of water (plant sap) moves through the hose, most of the particles stay put. If the water pressure is increased to a heavy flow, more of the sand particles are pushed through the hose.

With higher pressure inside, all other minerals in various forms are more easily moved throughout the plant, to where the plant needs them. This vascular pressure is especially important for larger plants with heavy branching, as more energy is required to move nutrients along these complex and far-reaching pathways.

Silicic Acid and Micro Elements

Silica deposits in the epidermal cells of plants act as a barrier against penetration of invading fungi. To penetrate the leaves, a pathogen must get through the wax, then penetrate the hard, rigid layer of silica mineral, before it even reaches the cell wall.

Silica doesn’t kill the pathogen. It simply blocks the fungal spores from attaching, allowing the plant to maintain its health and strength. This is the best preventative approach.

There are compelling studies showing plants moving extra silicic acid to points of attack and stress, in the case of insects, fungi infestation or breakage, in an effort to resist and repair. This is much like when we get a cut; platelets in our blood rush to the cut to create a clot while the wound heals. The additional silica deposits create even stronger tissue.

Most Silicon is Not Bioavailable

Before silicon can be taken up into the roots and throughout the tissue, it must first be converted by microbes into silicic acid, in a process known as ‘silicification‘. This natural process is slow; it can take weeks or months to occur on any noticeable scale.

The most common agriculture input forms of silicon are Potassium Silicate (K2SiO3) and Calcium Silicate (Ca2SiO4). Much of the naturally occurring silicon is in the form of Silica (SiO2). These forms, when unprocessed, are not bioavailable to plants.

For indoor applications, speed and bioavailability are critical. Many times crops are grown and harvested in a matter of weeks, or a couple months. The growing medium is frequently discarded, or sterilised before reuse. This destroys the micro-life populations, minimising the process of silicification.

Left in the Dark

Scientific studies concerning Silicon in plants have proven difficult to conduct. For one, it is nearly impossible to run a ‘control’ group during research, for a variety of reasons. Additionally, Silicon is not commonly considered ‘essential’ for plant growth. Only recently was it correctly classified as a beneficial nutrient. Silicon has simply been taken for granted.

In spite of this, the effects of silicon on plants are remarkable. Without bioavailable Silicon, plants do not achieve their greatest potential. It’s easy to see why many growers have problems in their garden, when bioavailable Silicon is not present.

The Key to Silicone Uptake

It is biotic life – microbes– that convert unavailable forms of Silicon into SilicicAcid; the only bioavailable form of Silicon.

This process is very slow; it’s also dependent on myriad factors. It’s common for a grower to add Silicon supplements and still not experience the true benefits of Silicon.

Pure Silicic Acid, when stabilised (as in Fasilitor), is “packed” in polymer form. It “unpacks” into monomer form when added to clean water, allowing it to enter the plant and carry nutrients (such as Boron and Molybdenum) along with it. Over time, Silicic Acid will ‘repolymerise’.

This is why it is important to mix fresh nutrients and feed immediately.


The flagship of the APTUS product lineup. FASiLITOR is pure, concentrated, and fast-acting.

FASiLITOR increases the variety of minerals being trans-located throughout the plant at any given time. The resultant mature, robust growth is a consequence of the complete formation of nutrient pathways, with increased mineral variety and density in transport to the plant cells.

If you are experiencing nutrient deficiencies, FASiLITOR can often help correct these apparent effects. You may think this is just a silica-based solution… but it truly is unlike any other silica product on the market.

FASiLITOR’s patented formula works by increasing vascular pressure within the plant, heightening mineral translocation throughout its entire structure, resulting in more complete, robust, and quality tissue formation.

FASiLITOR‘Monomer Silicic Acid’ – Features

Increases resistance to abiotic stresses, such as temperature, wind and drought
Increases resistance to biotic stresses, such as pests and pathogens
Improves uptake, absorption, and utilisation of nutrients
Stronger cell structure and epidermis layer creates a thicker tissue(increases dry yield)
Reduces inter-nodal spacing, by adjusting mineral translocation to new limbs
Bioavailable for up to 4 days before polarisation

FASiLITOR Key Ingredients

Silicic Acid – Mineral translocation adjuster, cell wall strengthener, abiotic and biotic stress reduction agent
Boron – Precursor to cell wall formation, trans-locator of plant energy (sugars), beneficial agent for flower and fruit formation
Molybdenum – Creator of crucial beneficial plant enzymes, synthesiser of organic phosphorous, and crucial to atmospheric nitrogen fixing bacteria


In a soil-container environment, FASiLITOR, through the action of silicic acid, will work to regulate how much of a mineral is let into the plant
Pour FASiLITOR into container of choice for measuring
Great for root drench or foliar spray
Do not contaminate with measuring instruments
Always mix in first – let it sit for 2 minutes before adding other nutrients
Not to be used in week-long reservoirs – alternatively, one may use in foliar applications


Add Fasilitor to the water in your reservoir first, before introducing any other products. This is important, due to the method in which the monomer-silicic-acid particles are stabilised.
Failure to follow this direction will result in a significant loss of Fasilitor’s benefits.

L-Amino Acids and Minerals

Amino Acids are the building blocks of all life on earth. They participate in many of the critical functions of biological systems. Without Amino Acids, life would never have formed and would cease to exist… safe to say, they are pretty important. We’ll look at what specific role/s Amino Acids play in plant development… but first, let’s look at what Amino Acids are.

There are around 500 known Amino Acids. For our purposes, we’ll keep it simple.

There’s an important distinction between L-Amino Acids (left-handed) and D-Amino Acids (right-handed). Plants have decided that the only type of amino acids they can use are the ‘left handed’ L-Amino variety… with very rare exceptions.

In natural soil environments, with healthy, thriving ecosystems, plants obtain L-Amino Acids from the process of decaying organic matter. When necessary, they synthesise what is needed, themselves. Unfortunately, modern agriculture has destroyed healthy soil microbial life; in many contexts, there may not be sufficient levels of naturally occurring L-Amino Acids to support thriving plant life.

If plants must expend their energy on amino acid production, they are wasting their precious resources on surviving, rather than selecting for quality and yield enhancement.

Before L-Amino Acids can perform their essential functions within plants, they must be bioavailable. Simply applying L-Amino Acids to the plant is not enough. In order to be absorbed either through the roots or leaf tissue, L-Amino Acids must be in free form, or as peptides. If they are combined into long-chains, the molecules are too large to permeate the plant tissue.


STARTBOOST is a powerful, yet natural stimulator of plant tissue formation. Its special ingredient is organic Nitrogen.

As a natural chelator of the already-existing elements present in your planting medium, it’s the L-Amino Acids in STARTBOOST that spur enzymatic digestion of natural materials; leading to production of healthy, organic Nitrogen compounds within your medium.

The synergy of natural ingredients achieved within STARTBOOST promotes the transport of nutritional elements across plant cell membranes, while simultaneously reducing levels of toxic elements in the growing medium. The organic Nitrogen provided by L-Amino Acids promotes robust vegetative growth and photosynthesis, without risk of burning or overdose.

Along with FASiLITOR, STARTBOOST is a foundational product in the APTUS Plant Tech Premium Collection.


Fully Organic
Wide spectrum of natural L-Amino Acids provides beneficial stimuli to the bacteria population within the planting medium.
Humic Acid has a positive effect on plant physiology; influencing nutrient uptake and complex mineral/root system interactions found within the planting medium

STARTBOOST Key Ingredients

APTUS STARTBOOST consists of two natural ingredients:

Humic Acid – Humic substances are natural chelators, and the building blocks of soil structure and health.
Protein Hydrolysate – Provides organic Nitrogen to the medium through L-Amino Acids, stimulating biotic life


STARTBOOST is a beneficial agent for the propagation of seeds and cuttings
is excellent for use in a root drench, or foliar spray
keep STARTBOOST in your reservoir for more than 2-3 days, in order to avoid organic biofilm buildup and blockage of irrigation drip lines
Use a 1:1000 dilution to feed new clones (pre-soak), or to start from seeds (1 ml per litre)
During transplant, dip the roots of the plants directly in a 1:100 mixture (10 ml per litre)


Begin feeding with STARTBOOST (plus FASiLITOR) as soon as your plants develop initial roots and leaves.
Continue adding STARTBOOST to your reservoir in every feeding during the entire vegetative phase, and into the first week of flowering, to assist with a healthy transition into the ‘bloom cycle’.

ECOZEN is a blend of beneficial enzymes that boost and stimulatemicro life. It’s a root and soil conditioner that works in conjunction with microbial life and your medium’s bioavailable nutrition. ECOZEN’s influence over the microbiome proves widely useful in performing certain macro-functions throughout the growing process.

ECOZEN keeps root systems and mediums clean; flushing outdead matter, improving overall medium absorption and reducing residue. ECOZEN also stabilises the EC (Electrical Conductivity) of mediums, and prevents the buildup of salinity in reservoirs.

All in all, this means that ECOZENdecreasesnutrient lockout. It also allows growers to fertilise later in the growth cycle, without risk of salt buildup affecting the quality of the end product.

ECOZEN‘wipes the canvas’ and neutralises your mistakes. It’s the perfect tool for those struggling with mineral antagonisms and ‘nutrient lockout’.

ECOZEN – Features

ECOZEN actively contributes to the soil health and rhizosphere of your medium, maintaining active nutrient uptake
contains enzyme complexes that transform accumulated or precipitated salts into usable plant nutrients. This helps to stabilise EC in the medium, and improves the plant’s natural ability to absorb nutrients
Growing mediums can be used longer and for multiple cycles with ECOZEN (less medium replacement saves cost and labour-time)

ECOZEN Key Ingredients

Cellulase A ‘root zone conditioner’. As roots grow, parts die off to make room for new growth. This results in cellulose (starchy plant matter) accumulating around the roots, inhibiting nutrient absorption and microbial development. The cellulase in ECOZENbreaks down cellulose, keeping the roots clean.
Beta-Glucanase Enzyme Complexes Functioning as a ‘root zone conditioner’, B-GEC’s transform precipitated nutrient salts into plant available nutrients, minimising build-up and increasing uptake.
Manganese –A crucial component for photosynthesis that stimulates micro-life; which, in turn, helps to further break down and recycle the materials that have already been broken down by the enzymes. High concentrations of manganese correlate to high levels of sugars in plants.


Reuse your grow medium for multiple cycles
Do not allow ECOZEN to sit in a reservoir with nutrients for more than a few hours – always add just before feeding
It’s advised to use this product as a flushing tool
ECOZEN is unsuitable to keep in a reservoir for any more than 24 hours
Flush medium between cycles with a higher dosage of ECOZEN, to clean out dead plant material and accumulated nutrient salts
Use ECOZEN at least once a week to keep the root area clean and nutrient assimilation optimised


Add ECOZEN to your nutrient mixture at every feeding, during all stages of plant growth, to keep the medium clean and healthy. ECOZEN may also be applied at double strength, once per week, if desired.
The enzymes in ECOZEN should start to work instantly, especially at temperatures higher than 20 degrees celsius.

BLOOMBOOST, true to its name, is a ‘bloom booster’ and quality enhancer, used throughout the entirety of the plant’s lifespan. It’s an excellent all-in-one health additive for your plants during their reproductive phase of growth.

BLOOMBOOSTcontains a blend of three essential plant-available elements, including Potassium, Sulphur, and Boron. These elements work together to increase fruit/flower size, fibre mass and overall bud quality.

APTUS has designed this product to provide your plants with these elements in precise amounts, at desired times during the growth cycle, to ensure maximised harvests.


Fully Organic Product
BLOOMBOOST contains elements that are crucial to the formation of certain oils and volatile aromatic compounds within plants.
BLOOMBOOSTassists in the development of healthy plant reproductive systems
BLOOMBOOST is the precursor to the healthy formation of chlorophyll, for optimal photosynthetic activity during the ‘bloom phase’.

BLOOMBOOST Key Ingredients

Potassium – Helps to form healthy, fibrous fruits and flowers. The amount of potassium in APTUS products is based on Dr. Albreicht’stheories of mineral antagonism. This means that BLOOMBOOST better provides the benefits of potassium in initial stages of flower development.
Sulphur – A crucial component in the formation of proteins and plant hormones, Sulphur aids in the formation of certain oils and volatile compounds found in particular plants. Sulphur brings out the aromatic characteristics of your plants in early stages of development, leading to a mature aroma by harvest.
Boron – Essential agent for healthy cell wall synthesis and cell division. It preserves the integrity of various membranes within the plant, contributing to structural integrity during flower development.


Great for root drench or foliar spray
BLOOMBOOST may be used at a higher dilution ratio (up to 1mL per 2.5L) for an increased result in quality. Be sure your PPM and base nutrient (bloom fertiliser) mixture will allow for increased dosage.
BLOOMBOOST can be effectively used through harvest without any negative impact on quality or flavour.


Use BLOOMBOOSTthroughout the fruiting and flowering phases of growth.
You should add BLOOMBOOST to your reservoir at every feeding; from the second week of the flowering stage, until harvest.This will yield increased flower setting, larger harvests, and a heightened aroma to your end products.
An organic plant fertiliser that prevents Calcium (Ca) and Magnesium (Mg) deficiencies, while stimulating powerful fruit set and development.
Calcium and Magnesium are easily locked up or combined with other minerals in the growing medium, forming what we call “junk salts”.
This active behaviour is a big deal, when you’re trying to dial in supplementation of Calcium and Magnesium for your plants.
Most Calcium/Magnesium products are classic mineral salt formulations.MASSBOOSTis different… APTUS takes a unique approach. Their Calcium/Magnesium is chelated with natural amino acids; much like other products in their line, such as PEAKBOOST and FINALEBOOST.
MASSBOOSTis a pure source of nutrition, which allows the minerals in a medium to be more-or-less directly assimilated into a plant organism. An uninterrupted supply of Calcium allows for stout flowers, stems and leaves, as well as the continued healthy formation of new plant tissue. Steady, bioavailable Calcium prevents blossom end rot, dropped flowering sites, and necrosis of the leaf tissue.

MASSBOOST – Features

Provides Organic Nitrogen from L-Amino Acids, stimulating plant development
Improves structure and firmness of flowers and fruits
High Bioavailability
100% water soluble; leaves no residue
Cost effective and stable

MASSBOOST Key Ingredients

Chelated Calcium and Magnesium allows for optimal supply of nutrients to plant enzymes. Magnesium is the central core of the chlorophyll molecule. A chelated supply ensures continued, robust chlorophyll development, so that the plant may perform photosynthesis optimally.
Contains no Chlorides or ‘ballast salts’, minimising the formation of ‘junk salts’ in your planting medium.


When mixing with any Phosphorous supplement (for instance, PEAKBOOST or other mineral fertilisers), be sure to allow one to mix into solution before adding the other, to prevent the formation of undesirable compounds.
Pay attention when mixing PEAKBOOST or other Phosphorous-based products with MASSBOOST, as they can react with each other.
You can use lower doses of MASSBOOST with PEAKBOOST & FINALEBOOSTin the final weeks for yield, firmness, and quality.
However, MASSBOOST contains low levels of nitrates that, when applied at a high dosage to young or weak plants, can cause tip burn. If you’re using MASSBOOST during early growth, be sure to start with a lower dosage; gradually work your way up to full dosage, based on your plant’s response.
MASSBOOST can be used in light doses in the earlier growing phases.


Add MASSBOOST to your reservoir during weeks 3, 5, and 7 of the flowering stage. Week 8 is optional.

To reduce nutrient cost, we recommend that users opt for a cheap mineral Cal/Mag (such as CalMax) for all of Vegetative phase, as well as weeks 1, 2, 4, 6, & 8 of Flowering.
MASSBOOST is not to be used in direct conjunction with PEAKBOOST (P)or FINALEBOOST (K). Because MASSBOOST doesn’t contain ballast salts, do not mix to regular EC levels. Typically, BASEis 300-400ppms lower.
Stick to the recommended dosage (1-2ml per 1L).

APTUS PEAKBOOST is an organic Phosphorous booster with a powerful stimulant effect on the blooming process. This product is all about making a massive difference to the phenotypical expression of your plant at its peak.

PEAKBOOSTprovides optimal chelated Phosphorous, with elements added that are usually antagonised away; including Zinc, Iron and Copper.
APTUS moves the vast majority of Phosphorous for the bloom cycle into this one product; allowing absolute control for heightened phosphorus application throughout specific phases of a plant’s growth cycle.
The Phosphorous in APTUS PEAKBOOST is chelated into an organo-mineral product. With the addition of L-Amino Acids, APTUS Phosphorous has eyes only for the plant’s roots. The specific application of chelated Phosphorous allows for optimal health; the negative antagonistic effects of cheap bulk products, which contain high amounts of both Phosphorous and Potassium, are not there in PEAKBOOST.

PEAKBOOST – Features

PEAKBOOST, and its sibling, FINALEBOOST, are the ultimate development and bulking solutions in the APTUS line
Provides high levels of natural, bioavailable Phosphorus during the early generative and bloom stages
PEAKBOOST minimises antagonisms and ‘nutrient lockout’
High Bioavailability, 100% water soluble and leaves no residue

PEAKBOOST Key Ingredients

High Concentrations of natural Phosphorous stimulate flower bud formation, set, and development.
Organic Nitrogen provided by L-Amino Acids promote robust tissue formation and photosynthesis, while minimising risk of burning or overdose.


Gradually increase PEAKBOOST dosage throughout the bloom cycle, until your flowers are well set and ready for bulking.
It is okay to start the FINALEBOOST transition earlier with plant genetics that have longer maturation periods.


Add PEAKBOOST to your reservoir every feeding, from the second week to the sixth week of the flowering stage. It’s okay to extend or shorten the usage of PEAKBOOST, based on the total flowering time of your specific plant.
When mixing with any Calcium supplements (such as MASSBOOST), be sure to allow one to mix in the solution before adding the other, to minimise the formation of Calcium-Phosphate bonds, which render nutrients unavailable to the plant.

FINALEBOOST is a maturation booster that contains the vast majority of Potassium used during the APTUS bloom cycle. With Potassium loaded into one product, APTUS allows for scientific control of heightened potassium application throughout specific phases of a plant’s growth cycle.

The Potassium in APTUS FINALEBOOST is chelated into an organo-mineral product. With the addition of L-Amino Acids, the Potassium has eyes only for the plants’ roots.
FINALEBOOSTwill unlock your plant’s true genetic potential; the results will be right there in the final harvest.


FINALEBOOST stimulates fruit and bud maturation, leading to a firmer, more nutritious end product.
FINALEBOOST minimises antagonisms and ‘nutrient lockout’
FINALEBOOSTimproves crop quality by increasing production of sugars and L-Amino Acids
FINALEBOOST improves the functions of the plants’ respiratory system, by regulating the opening of the stomata. When the stomata is deficient, plants can wilt unnecessarily
Powerful stimulating effect on the blooming and finishing process
High Bioavailability, 100% water soluble and leaves no residue

FINALEBOOST Key Ingredients

Chelated Potassium allows for optimal health, by removing the negative antagonistic effects of cheap bulk Phosphorous/Potassium products. Nitrogen, Calcium and Magnesium will remain bioavailable in your reservoir, at levels that P/K mixes can never achieve.
Organic Nitrogen provided by L-Amino Acids promotes robust tissue formation and photosynthesis, while minimising risk of burning or overdose.
High Concentrationsof Sulphur combine with BLOOMBOOST to help your plants produce high quality buds, aromas and terpenes.


Foliar references: you don’t want to spray Sulphur on your finished, pristine flowers.
With longer flowering genetics, you may want to fast track the PEAKBOOST/FINALEBOOST transition, so that the last 2-3 weeks of Flowering are without PEAKBOOST entirely.


Add FINALEBOOST to your reservoir during weeks five (5) through eight(8) of the Flowering phase.

Some plants may be able to receive FINALEBOOST at rates 2-3x higher than recommended, to increase weight and quality during finishing. Be sure to test this on a few plants before applying consistently at these rates.
Gradually increase the FINALEBOOST dosage throughout the bloom cycle, whilst still using PEAKBOOST. As the dosage of FINALEBOOST increases, PEAKBOOSTshould decrease.

If starting from seed, dilute BASE into feed solution at a rate of 0.5mL per litre, along with all other vegetative APTUS additives (FASiLITOR, STARTBOOST, MASSBOOST) from first signs of leaves.
Increase BASE dose to 1mL per Litre as plants begin to establish themselves.
If you’re adding MASSBOOST, be sure to add BASE to your reservoir first. Then, mix for 3 minutes.
In high-intensity flowering situations (where plants are grouped together in one system, or if you have a heavy feeder), you may increase feed levels to 2mL per Litre.
Always check your EC before feeding. APTUS BASE does not include chlorides or ballast salts, that cause unnecessary contamination of the growing substrate. Without ballast salts or chlorides, the EC reading taken from your feed solution gives you a true view of the nutrient concentration.

How to Use BASE

APTUS BASE is easy to use throughout the growth cycle. Simply add at a rate of 1 mL per litre, up to a maximum of 2 mL per litre, if needed.

BASEBOOSTis a time-release, 100% organic pellet fertiliser, which provides complete nutrition for plant development for up to 3 months.

Each application lasts 2-3 months, and can be reapplied for longer cycles. BASEBOOST is specially formulated with macro-nutrients and micro-nutrients, L-Amino Acids and other biostimulants, to enhance plant development over a period of time.

BASEBOOSTis an effective standalone as a complete fertiliser, with very little effort. For advanced growers looking to maximise yields, BASEBOOST is an effective replacement for typical base NPK nutrients… in combination with the rest of the APTUS Premium Collection boosters.


Full spectrum, organic L-Amino Acids provide growth materials, plant and microbe biostimulation, as well as boosting beneficial bacteria populations.
Organic Nitrogen provided by L-Amino Acids promotes robust vegetative growth and photosynthesis, without risk of burning or overdose.
Time-released nutrition feeds plants as they require the nutrients, rather than being force-fed with chemical salts.
Complete nutrient profile minimises plant stress due to environmental conditions, such as pests and pathogens. Healthier plants = greater quality and yield.
Complete formulation reduces fertiliser input and work
Conditions soil, improves plant development, and stimulates micro-life
Simple and complete, 100% organic plant nutrition – nothing else but water is required for a 3 month cycle of vegetating and flowering
Perfect for remote locations and long lasting crop cycles
Long shelf-life if properly stored

BASEBOOST Key Ingredients

L-Amino Acids, which provide Organic Nitrogen (N)
Primary macro-nutrients: Nitrogen (N), Phosphorus (P), Potassium (K)
Secondary macro-nutrients: Calcium (Ca), Magnesium (Mg) and Sulfur (S)
Organically chelated micro-nutrients such as, Boron (B), Iron (Fe), Manganese (Mn), Zinc (Zn)


Use more pellets for sandy soil (200 grams per plant) than for clay or heavy soil (100 grams per plant), per cycle (2-3 months)
If your cycle is longer than 3 months, apply a second treatment as topdressing and water from the top, or mix pellets into the top couple inches of soil
In case of deficiencies, simply add more pellets as topdressing, and water from the top. The pellets will be solubilised and the nutrients assimilated by the plant
Mix into the ground during soil preparation, or simply place at the bottom of each planting hole.
For better results outdoors, use with FASiLITOR, STARTBOOST and BLOOMBOOST.
For better effect indoors, use with all boosters (STARTBOOST, BLOOMBOOST, PEAKBOOST, FINALEBOOST)
You can apply BASEBOOST during transplanting by mixing into the growing medium; or, as a topdressing, to extend the growing cycle (particularly outdoors)

APTUS BREAKOUT POWDER is an easy-to-use flower setting and bulking product that provides huge value for both small and large scale cultivators, alike.

BREAKOUT POWDERis formulated using the highest quality water-soluble concentrates of Phosphorous, Potassium, and Sulphur, helping to achieve higher yields and better taste.

APTUS BREAKOUT POWDER takes the guess-work out of application; no scales or extra devices required. BREAKOUT POWDER is an economical, stable and powerful flower enhancer that promotes additional flower growth and development in the last 3 weeks of the bloom phase.

With that said, BREAKOUT POWDER is not an equivalent to PEAKBOOST and FINALEBOOST. The APTUS ‘Mineral Antagonism’ principle of separating Phosphorous and Potassium is not present in this product. BREAKOUT POWDER provides a high quality option for gardeners in need of a cost effective, water-soluble flowering additive.


Low cost and high quality source of important Phosphorous, Potassium and Sulphur
BREAKOUT POWDER is economical; with an extremely low dilution rate of 100 grams to 100 – 200 Litres
BREAKOUT POWDER provides a strong source of Sulphur, to enhance colours and flavours during maturation stage
Pre filled easy-measure 100g sachets allow you to pour a half (50g per 100 litres) or full (100g per 100 litres) strength application


BREAKOUT POWDER consists of Mono-Potassium Phosphate: a concentrated source of both Phosphorous and Potassium.

In addition, Breakout Powder contains potassium and magnesium sulfates to ensure strong aroma with the highest quality end products.
Phosphorous (P): Improver of overall crop quality, crucial element in photosynthetic units of energy
Potassium (K): Essential component for the production of photosynthetic units of energy, regulator of plant-water content and CO2 consumption
Sulfur (S): Vital component of plant proteins, essential to the formation of certain oils in specific plants


Always ensure all other APTUS products have been correctly added to the reservoir and mixed well before adding BREAKOUT POWDER
For best results and fruit set, always ensure BREAKOUT POWDER is used during the last 3 weeks of flowering, or the last 3 weeks of your feeding schedule
Use only at 50 grams (half a sachet) per 100L for the first week (3rd last week of bloom feed schedule), and 100g per 100L for the second and third
Do not use in addition to PEAKBOOST or FINALEBOOST
Always check your EC after adding BREAKOUT POWDER to your reservoir. Adjust with fresh water, if necessary.

Add one sachet at a time to your mixed reservoir and stir well. Add BREAKOUT POWDER after all other fertilisers and boosters have been added.

Always add FASiLITOR to your clean reservoir before any other products. Use during the last 3 weeks of flowering; or if flushing, the last 3 weeks of your feeding schedule.

APTUS Tips for Plant Growth Success

  • Feed at the right time, and the right amount, in the right form.
  • Recognise the ways in which your plant desires balance and moderation.
  • Stay away from fertiliser “cocktail” recipes, which cause imbalanced feeding and unknown problems in the growing medium. Thanks to the unknown nutrient mixing, these issues are usually difficult to ‘troubleshoot’.
  • When you have a problem with your grow… be sure to trace your steps back, and start at the beginning.
Wielded properly, these targeted insights into plant growth, nutrient supplementation and medium cycling (provided alongside premium APTUS products) go a long way in assisting newbies to achieve plump, healthy specimens. From the earliest stages of plant development, to the moment of harvest… APTUS has your back!
