Top Tips for adding CO2
Here's how to get the best bang for your buck when adding CO2.
1) Be aware of extractor fans
Extracting air? To stop your CO2 getting sucked out by fans, make sure you:
- Keep any CO2 bags or dosers well away from your extraction ducting
- Mix air as you dose
- Add enough CO2
2) Circulate air
CO2 is heavier than air. Left alone it can fall down and pool at ground level.
To prevent this, mix your air. This’ll create an even CO2 level throughout your grow room.
Something like the Quest F9 Air Mover is great!
3) Add CO2 gradually
Aim to gradually build up the supply of CO2 in your grow room.
4) Increase your feeds
Adding CO2 increases growth – make sure you’ve got the nutrients and water to support it by feeding plants more
5) If possible, switch off your extraction system during dosing
This gives plants the chance to absorb way more CO2 during dosing. Only turn fans off for a short time, and only if your temperature and humidity won’t rise too much.
6) Don’t forget propane burners produce heat
When you spec up your climate control system you’ll need to account for them.
