I have a quick question. I’ve seen plenty here about what size exhaust and intake fans are needed. But I don’t understand how much air can be recirculated back into the tent. (I’m gonna use my 4x4.)
For example, I could run my exhaust duct around to blow into one of the intake holes, and I wouldn’t lose too much of the heat generated by my light. I’d like to keep some of that heat in the winter, since my tent will be in my unheated basement. I figure I can leave a gap between the end of the exhaust duct and the intake so there will be some fresh air going in. Any suggestions about this?
And what kind of cues do plants give to tell their people that they aren’t getting enough fresh air from the room into the tent?
Total noob question, I know, but that’s what I am, lol. You all are great. Ive learned everything i know here, just getting geared up for my first indoor grow amd learning everything I can.
