About a dozen years ago, after I had a few indoor grows under my belt, I sought out an experienced indoor gardner, someone who had been doing it since the early 70's. I wanted to increase my yield.
I detailed my set-up. Lights & soil & nutes all a-ok.
I told him about my ventilation--leaving the door open during lights on with a fan blowing in.
"Bingo" he said.
He told me I needed flo-through ventilation. 2 fans (intake and exhaust) in a closed environment.
I thought to myself "how can fresh air increase yield?" and ignored his advice.
But the next grow chamber I constructed, I remembered and put in excellent vemtilation.
And was amazed at the difference.
Faster growth and bigger buds.
Because pot "eats" CO2. At a few hundred ppm's in the ambient atmosphere, the plant needs all the fresh air it can get.
Indoors we attempt to re-create the outside environment. And outside is fresh air.
Excellent ventilation is the link that is missing from many growspace's.
Spend a little time and $ and prove it to yourself.
