How to Pick a Growing System
Choosing a growing system? Before you buy, ask yourself these 8 questions.
How much floor space have you got?
First, your system needs to fit!
You also need space to spare for lateral plant growth and for you to access your system.
To give you a rough idea, here's what you could get in our three most popular size tents:
We've been a bit conservative here so you don't overcrowd plants or struggle with maintenance.
How much head room do you have?
In any tent, you need to keep a safe gap between your canopy layer and your lights.
If you don’t have much height...
..it can be a tight squeeze.
Try to get plants as close to the floor as you can.
Why? To leave a bigger gap between plants and your lights as plants grow.
Or you can always put pots straight onto the floor or on Flexi-Trays.
If you’ve got the headroom...
...you can afford to use a taller system – like a RhizoWilma.
3. Ease of Use
How much time have you got?
The more automated your system, the more time you’ll save. Look for:
Can you check your system daily?
Do you want to use growing media?
If growing organically, you need to use media...biological, organic nutrients and hydro systems don’t mix well.
Using media is also a more forgiving way to grow. Roots are insulated from temperature changes and you don’t have to tweak your feed as much.
You can get a bigger yield if you use a hydro system. Without growing media:
- Roots are incredible!
- Roots have more access to oxygen
- Nutrient uptake is faster
- You get an incredible yield
- You don’t have to pot on
- You can’t underwater or overwater
There’s no media to restrict growth…better yet, roots have more access to oxygen, and instant access to nutrients.
Growth is amazing!
Whether you use media or not, there’s a system for you.
6. Number of Plant Sites
How many plants should you grow?
A lot of new growers try to grow too many plants.
They mistakenly think “more plants = bigger yield”
Don’t do this.
You’re best off aiming for 1 - 4 plants per square metre.
You can actually get the same yield from 1 big plant as you do 4 smaller plants grown in the same space.
If you've got a bigger area, you need to do a bit of maths.
Work out how much floor space you have
(Multiply your tent's H x W x D)
e.g. a 3m x 3m x 2m tent has 3 x 3 = 9 sq.m of floor space.
(floor space) x (number of plants you want to grow per sq, m)
e.g. a 9sq.m x 3 plants = 18 pot system
If you have more than 10 plants to manage, do yourself a favour and choose a bigger system that feeds plants from one tank.
7. Pot Size
How big are your plants?
If you’re growing big plants, make sure your pots are big enough!
Try to use around 60L of growing media per 1m -1.2m
For hydroponic systems it’s a case of the bigger the better. Bigger pots = more water = slower pH & CF changes.
