    I'm in the 10th week of flowering and when my lights are on at night the humidity stayed at 30-40% but when their off during the day and I go in to turn them back on it gets upto 60% is there any way to lower humidity without a dehumidifier? It's a small closet, an ideas or tips would be great

    Pretty sure your experiencing a good thing during the night cycle. Plants r doing their thing and releasing there goods. I'll bet your plants look great. But if u don't have enough air movement in there then u could experience problems. So to answer your question yes get more fans moving air.

    Alright thanks ill get another fan in there, I have 5 plants and 4 of them do look really nice but a little small since I only have like 370 watts of cfl going, but its my first grow and I've learned a lot so I'm enjoying it

    Hey man as long as you got good ventilation you will be fine. If the humidity was 90% all the timw the you would have problems. Last season I had some outdoors growing and we had about 3 weeks (at week 6) of 80-100 percent humidity all the time. But had no dramas with mold or anything like that.
    Good luck

    Yeah as long as you have good airflow around them you won't have any problems at 60% humidity, I battled much worse humidity than that this year, seems like it's rained almost every day here. Never had a problem even with a 75% RH
