High RH at night
T1000started grow question 2 years ago
Hi,so I noticed that the RH usually goes up from 55% to 85% at night when the ventilation and lights turns off and I was wondering if it was dangerous for my plants especially when they will flower.If yes then I will have to find a way to let the ventilation going at night.Thanks

Keeping all that ventilation gear running 24/7 will keep the humidity down , deter bugs from setting in , stop bud rot before it starts and strengthens your stems for all that bud . You might be able to ramp down the intake and exhaust a bit but keep those circulating fans going .

My extractor and fan are also off at night as i sleep next to the tent but my RH range is more 30% to 60%. I do experience some mold with some strains, not all, ;reaching 80% is a bit high i suggest you find a way to let ventilation going at night.

ventillation should be running... and will solve the problem.
gas exchange is still occuring in the dark. plus, you do't want stagnant air volume even if it is circulated (are fans on? if not get those going 24/7 too).
unless you have a hergrometer hooked to fan control, 24/7 is the way to go..
