i had mine coming on 15 off 30 min during veg, i have it on for the full 12 hours in flowering blowing gently to keep the temp right. all depends what lights your using.alright how many hours a day should i have a fan on my plant in veg phase, and flower phase (if different)
also do you think that opening a crawl space in the closet for a couple hours a day with fan blowing towards it would be enough for ventilation?
so the only reason you have the fan on the plant in flowering is to maintain temp?i had mine coming on 15 off 30 min during veg, i have it on for the full 12 hours in flowering blowing gently to keep the temp right. all depends what lights your using.
