Thanks oregon.I'm in 3 weeks flowering .the light burns out some of the humidity.But when I go in there now in the morning.51% and drops to 42% threw the day.Yours will increase the room as they grow.I think it's a survivle thing they do.You can put a pan/bucket.Or jar with a towle and water.This brings it up some.But from what i have seen a humidifier is overated.The plants do it on there own and do fine.Good luck oregon024
