Fans can also help to remove some of the extra heat in your grow room generated by your lighting system. Excess heat near the tips of your plants can cause them to grow thin and wiry and their flowers may end up opening up and losing quite a lot of terpenes.
We’re going to have a quick look through the items we mentioned earlier on our shopping list so that you can figure out for your own which models work best for you and which ones you don’t need.
1.2×1.2×2 = 2.88 x 60 = 172.8m 3 . This is the strength that your extraction fan will have to reach to be as effective as possible.
This means that the perfect odor filter for this set up would have a 125mm opening and should be almost 500m3/h. This avoids any mishaps with the filtration system, which can happen if the filter strength is less than the actual extraction itself, causing air buildup. If this were to happen it may be fatal for your plants, especially if you don’t realize that it’s happened.
You need to calculate the amount of space you’ll need while also keeping in mind the fact that you’ll need to be able to move about and get to your plants and devices. You’ll also need to think about where you want to place the intake and outtake lines for your extraction fan.
In order to calculate the inline fan strength you’ll need to calculate a fourth of your extraction strength. So, if you have a 1.2×1.2x2m grow tent and a 600w lamp, you’ll need a 468m3/h extractor. So, for your inline fan you’ll need to calculate 468/4 which is 117m3/h – this is the type of intake that you’ll need.
- 250w: 150g, covers 80x80cm at 25-30cm from your plants
- 400w: 300g, covers 100x100cm at 40-50cm from your plants
- 600w: 450g, covers 120x120cm at 60-70cm from your plants
Inline fans are just as important as extraction fans, although if your extractor is strong enough it can create negative pressure which can cause air to come into your grow room without any sort of extra inline fans. This only works with Grow Tents, as they tend to come with passive breathing holes, although if you’re using a room or grow tent you’ll need to sort out air in-take yourself.
The materials needed to grow cannabis indoors vary quite a lot; we've put together a list of 10 of the main things you will need to grow cannabis indoors.
These plants were grown together from seed in the same environment. One yielded 6 ounces, the other yielded 9 ounces. Genetics makes a huge difference! Now imagine if they had been grown in different setups with different grow styles. Advice that works for one plant might not be good advice for the other!
3.) Light is probably the most important part of the growing equation
When you’re starting out, if you have a lot of room to grow and if it’s not what you’re banking your whole grow on, bagseed or other mystery seeds can be a fun experiment.
If you buy a seed of “Northern Light” strain by a particular breeder, it should grow very similarly to other “Northern Light” seeds from the same breeder. This is most true with trustworthy breeders.
When you have bad airflow, you may come across this. WPM actually looks like someone may have accidentally dropped some flour or other white powder on the leaves of your plant!
But truthfully, if you just need medicine for personal use, growing can be incredibly easy. Even if all you’re doing is a simple hand-watered grow, you can easily end up with several ounces of buds off your first plant, even if you make lots of mistakes!
But I’ve realized that as long as you give your cannabis the basic nutrients needed to grow, you really don’t need to know a lot about nutrients. In fact, if you ensure your plants are growing in a perfect environment, you can get incredible results using just basic nutrients, without any special supplements whatsoever!
