Radogast! thanks for your reply!
Glad to help, not sure where to start, here is my c02 share & a couple links to help with your clone question & ventilation question. I find it easier (for me) to help out members just like yourself, by asking you to post, your next question in my journal, thru the link below. I wish I could keep up w multiple journals, but I can't. Just jump into my thread and say someting related to what you read on the previous page, this way you can comment "I'm clueless" is a fine comment, THEN, ask ONE specific question, in my thread, at a time. This way you will get answers from myself & the many visitors that I get. I'll see you there very soon, I'll be awaiting a comment, then your question. give it a try! im not saying don't post here, you can do whatever you like here, i just cant come back here every day/hour to help. i am glad to help you, lets try it that way, u decide if this will get you more help. you'll meet great members, and they will come here , to your journal, when u build some rapport. just my 2 cents, good luck , hope to c u
So what you need to do is to feed the CO2 only at the same time you water them, this is the best moment for absorption. Assuming they water themselves (timers and pumps) then set up the CO2 in the same fashion. If you water them manually the feed CO2 immediately after you're done watering and for a few minutes only (15-25 probably).
CAN you feed the CO2 continuously? yes of course, the plants will love it, but remember that the roots need oxygen so you cannot displace that much oxygen or it could be counterproductive. Also, there has to be an air exchange, ideally 4x the volume/hour. So you do NEED an exhaust and either an active or passive intake. Otherwise humidity is going to rise all the way.
I ran the tent for 1 night without the exhaust fan because I didn't have time to install it and humidity rose to 99%, there was condensation on all the walls and ceiling, luckily it was just the one night and after installation of the fan everything went back to where it should be.
If you feel that feeding CO2 continuously will be better and you'll have better yields (I don't use CO2 so I wouldn't know) then don't waste it by running the exhaust at the same time. use timers to alternate their operation, i.e. fan for one hour, CO2 for one hour, fan for one hour, so on and so forth.
Hope this helps,
Good luck and happy growing!!
