A Guide for Growing Cannabis Indoors in Australia… When It’s Legal!


A True-Blue Indoor Grow

So you want to grow some dank erb’? Live in Australia? Confused by the yanks using the insane imperial system and telling you to buy products that only ship within the United States? Well, look no further, you’ve finally got it; An Australian Guide & Shopping List for Growing Cannabis Indoors…when it’s legal, of course!

This by no means is a definitive guide… consider it more of an easy how-to for any beginners looking to get started.

Now, I’m going to be honest here and say two things. First, I’m not an incredibly experienced grower. I can only share what has worked for me, and a lot of that is based on many hours of research. But, I have had great results, and am VERY satisfied with them. Second, this setup isn’t exactly the cheapest one around. You will be facing around $1000 to get started; however, this will pay itself off in the first grow. Let’s begin learning how to grow Cannabis indoors in Australia!

The following guide breaks down all of the items required into their own dedicated posts. Click the links to browse alternatives, or learn more information on why we selected what we did. This list can be played with however you wish; we actively encourage experimentation within your own growing operations.

Now: onto what I used to grow around 8-14 ounces of that sticky icky every 3 months.

Lights, Camera, Buds!

Horticulture Lighting Group (HLG)  260w LED Quantum Board 3000k Grow Light

This is an incredibly efficient LED grow light. You can purchase them in Australia at Quick Bloom Lights for $525! If you’re lucky, they’ll give you a discount if you ask them. 😉 It’s also purchasable on eBay for the same price, but occasionally you can find a discount code to get it cheaper! (Check OzBargin)

A bit expensive, but the light will pay itself off in the long run; particularly over HPS lights. Take a look at our article on choosing the right grow light for more information on why the HLG 260W was chosen.

You will also want to get yourself a 24-hour timer switch for $16 on eBay. This switch will allow you to program how long your lights are on for.

Ready, Steady, Tent!

Whether you pick up a tent or not is really up to you; but we highly advise it. For our list, we have used a 90cm x 50cm x 160cm grow tent, going for $89 on eBay. We like this tent because it fits very nicely into a mirrored closet. It’s not very wide, but it’s sufficient for 3 smaller plants, or 1 very large, well-trained plant. But feel free to grab a 90cm x 90cm x 200cm tent!

You can read more about selecting and maintaining your tent in our “Tents for Growing in Australia” article.

Mind, Body and Soil

When it comes to sourcing the soil for your plants, you can always pick some up from Bunnings, or at a local nursery. The best soil for cannabis is likely going to be a premium potting mix. The Osmocote Professional 25L Premium Potting Mix from Bunnings will do you alright, for just $8!

If you’re after some of the better soil, check out the CANNA Terra Professional soil from CANNA. You can purchase CANNA soil in Australia in a lot of hydroponic stores and nurseries. Take a look here to find your closest dealer.

Nourished With Nutrition

Much like humans, plants need nutrients and food to thrive; and cannabis is no exception! So, what are the best nutrients to give your cannabis plants in Australia? Well, that depends on a few factors. Are you doing an all-organic grow? Is it a hydroponic or coco coir grow, or are you just in straight up potting mix soil? Irregardless of all this, the most commonly used nutrients are:

  • Nitrogen (N)
  • Phosphorus (P)
  • Potassium (K)
  • Calcium (Ca)
  • Magnesium (Mg)
  • Sulphur (S)

When growing hydroponically, you’ll typically be growing without soil and using a substrate, instead; like rockwool, clay pebbles, coco-coir, or some other sort of mix.  Most indoor cannabis is grown hydroponically, even if grown in buckets or pots. Often, they’re still watered by hand. So don’t think ‘hydroponic’ has to mean a fully automated pump/water irrigation system!  Typically, nutrients for hydroponic cannabis are delivered in liquid form. These nutrients need to be diluted, so they’re not too strong for a plant (too much will kill your plants!)

Nutrients are typically split into two types: Part A and Part B. This is because you want different amounts of certain nutrients for different times within the plant’s life cycle. Products marketed as “grow” solutions are high in Nitrogen (N), which make it excellent for your plant’s vegetative growth. Products marketed as “Bloom” are high in Phosphorus (P), which help with flower development.

You need to be very careful when mixing up your hydroponic nutrients, as too much will cause plant damage and/or death! So start with lower amounts when starting out and slowly up your dosage to full strength.

For around $120 (including delivery) you can get yourself the complete range of nutrients needed for growing hydroponically. You can also check out our detailed article on nutrients for more information.

Seeding Up

One thing you’ll want to consider before picking your seeds is which strain will work best within your own circumstances. You’ll need to consider height, flowering time, the amount of yield, along with the psychoactive and palliative effects. Be sure to consult the infographic below to figure out which variety of seeds will work best for you.

Here’s a small list of strains that are easy to grow, organised into their genetic varieties. It’s important to note that the non-auto-flowering plants’ finish time is based on their flowering time. Typically, you will vegetate your plants for 2-4 weeks before flipping them to flower – so add that on to their completion time.

Pottery for Your Pot

When choosing the pots to grow your pot, it’s important to consider a few factors. You want to give your cannabis the best root growth and structure you can, so picking pots that can help with this is important.

Standard plant containers. These are typically made of clay. They are easy to find at any gardening store, or at Bunnings. The biggest issue with these pots is that they’re a bit heavy. When moving around your plants, it’s nice when they aren’t too much of a strain. These pots do retain water really well, though. This could be a positive or negative, depending on your grow.

Air Pots. These are made from plastic, but have holes all over the sides to allow for more oxygen and faster drainage. They’re also very cheap, and easily purchased on E-bay. They come flatpacked, meaning you assemble them yourself. Personally, I love these. You can use the holes to help train your plants. They drain very easily, though; as a result, you’ll likely need to water your plants more often. On the upside, it’s harder to overwater your plants!

Fabric/Smart Pots. These pots are similar to Air Pots. They allow for more oxygen to get to the roots, because they are made of fabric. They also allows for better drainage. These pots do dry out quicker than clay pots, but they’re super cheap, very effective, and easily purchased online.

Buckets. This is where you just take a bucket and put some holes in the bottom for drainage. A bucket will help you hold onto water longer than Air and Smart Pots. They’re like a clay pot, but are much cheaper. If you’re growing large plants, buckets can be a great choice!

Hydroponic Containers. If you’re considering a hydro grow with a water pump and a reservoir of water, you’ll be looking for hydro containers. This is where your cannabis will sit in water. Typically, you use baskets similar to these with clay balls as the soil medium. We don’t recommend this for beginners.

It’s also important to have a saucer below your pot to contain the water being drained. For more information on potting, check this link. 

Water and pH

What about that key ingredient: water? Well, first thing’s first. You’ll need a water can! You can pick one up in Bunnings, of course. I recommend grabbing at least a 9 litre watering can. Not too big, but not too small; your plants need a lot of water!
Next, you need to know how to feed your plants nutrients through the water. Read our nutrient guide for more.

And now, the most important part of watering. Checking and adjusting for pH to allow your plants to absorb nutrients most optimally. Cannabis plants thrive best in water that is between 5.5-6.5 pH, growing in coco-coir. I would suggest aiming for a pH of around 6.0 for growing hydroponically. If growing in soil plants, best to work at around 6.0-7.0 – a pH of around 6.5 will make your life very easy.

Remember, though; you don’t need to be exact. Just buy a pH metre, and be sure to keep it within range. If you want to know more about watering and acidity levels, check out this link.

Ventilation, Cooling, and Masking the Smell

Let’s face it: most of us don’t like the idea of our house reeking of cannabis – even if we’re keen on growing indoors. So, we need to figure out a way to mask the smell. It’s actually much easier than one would expect, with the help of a carbon filter and an exhaust fan. Air circulation and heat control are crucial for masking smells; they are also important for plant wellbeing. Keeping the air moving helps protect your plants from mould, bud rot and mildew. Controlling the heat keeps your plants from getting stressed under tough conditions.

To give your plants the best chance of surviving and growing big and healthy, you want fresh air in your tent, and you want the air to continually circulate. This is where an exhaust fan comes in handy. You’ll want to purchase one to take the hot air produced by your grow light outside of your tent. When it extracts this air, it will go through a carbon filter which will mask 99% of the smell. Your exhaust fan will ideally come with some silver exhaust tubing for directing where the hot air will go to.

If you’re doing a fairly small grow, we recommend a 4” exhaust fan and carbon filter. You can find the whole kit on ebay for $107 with tubing and the filter.  This is sufficient for tents no bigger than 90cm x 90cm x 180cm. However, if you’re around this size or bigger we strongly recommend a 6” exhaust fan. The 6” fan will give you the option to expand if you so choose to, and it has two speed options, fast and slow. The one we have selected on eBay that has ducting, noise reduction clambs and a carbon filter will set you back around $285.

Also look up low stress training and topping, so your plant grows like a bush, and not like a Christmas tree! Definitely the bread and butter of any grow
