I agree with the other posts.

Im very new to this growing but from the time ive spent looking at various posts and websites i would say air flow is VERY important.

I have invested two 5" fans pumping/ducting in fresh outside air into my grow and i also have one 16" fan inside moving the air around too.

I dont think you can ever have to much smoke eeeerrrrr i mean air :rastasmoke:
HugoPepe Reviewed by HugoPepe on . how important is ventilation? can it mean the difference between a healthy plant, and a dead plant? I know that people generally want to supply their plant with fresh air, but I would like to hear from someone with some real experience with that. Would a plant die if you kept it in a closed grow-closet, and only opened it every day or two? It's just that my intuition goes against the notion that plants can consume that much air. My intuition wants me to believe they consume miniscule amounts of air. Rating: 5
