Keep in mind that your flowering girls are expeling Co2 at night and breathe it in during the day. Don't want to make a toxic environment for them. And keep in mind that vegging plants need a higher rh than the flowering girls. 60% in veg and 40% during flowering. High humidity in the flower cycle can lead to bud rot. Good luck.

Will the Co2 from my flower box go into my veg box? and is it bad for Co2 to run during the night time under flowering plants? I know its a waste of Co2 but I dont really want to go get another co2 tank and regulator for my Rating: 5
