How about at higher day time levels like 1000-1500ppm ? As my generator has a light sensitive controller so it will keep those levels until the lights go out!. Its only some thing some one has mentioned to me so im trying to gather as much info as to whether its worth have some kind of extraction for say and hour after lights off perhaps??.Out in the real world co2 would be higher (generally speaking) at night than in the day. So in a room I would think that you may be able to change how fast a plant would ripen but you aren't going to be hurting anything by going one way or the other. Also, its likely that any number of things could affect your ripening more than the co2 input; 200ppm co2 at night vs. 2degree lower temps at night....
LMFAO ROFLNot tryin' to be a dick but.... Huh? (moses- meet me at camera three) I don't know about yours but mine don't put out co2. at all. ever. never did happen. And if they did, why aren't we just using that to feed the other cycles? And why would deforestation be such a big deal if trees were actually responsible for a lot of the greenhouse gasses?
