Creating something for additional CO² is not neccesary IMO, if you have good ventilation the plant get all the CO² it will ever need. Just watch it with the odor.
britewire Reviewed by britewire on . Trying to setup my new huge cabinet, need advice... All, I'm about to attempt to become an indoor grower. I've been researching for weeks, and just stopped by one of the local Hydro stores to talk to someone in person. I'm not the one to miss a detail usually, so when I say I'm researching, I mean I'm reading things like Marijuana Botany - the Propagation and Breeding of Distinctive Cannabis just to understand little things. I'm also reading every forum I can find. I'm not saying I understand it all, but I'm not just throwing a few bag seeds Rating: 5
