I am a week into flower right now and the humidity level is around 35-55% when they lights are on but about 60-78% when the are off. Are these numbers ok? I am concerned about the high level when they are off....
You NEED a dehumidifier or you will get mildew/mold. Generally the rule of thumb is no where above 55% and you are generally safe. My Humidity is around 40-55% but I would like it at a steady 35-45%.
I have a dehumidifier in the room that runs on/off every 2 hours. Should I add another passive intake and run the can fan 24/7 to suck out the humidity?
Thanks Dr. Green. Have you ever heard of Damp-Rid? It is a bag of stuff that hangs in a closet or whatever space you want and it sucks up the humidity. Thinking about trying it so i don't have to waste the electricity of running the fan for an additional 12 hours a day.
I just got some at Lowe's and the stuff is cheap. I'll use it starting tomorrow during my off cycle. Hopefully it works, I will post results.....
Now that the temps are generally lower due to the weather, my humidity during light on is about 25-30%. Is that too low?
I put 4 of the 2.5lb bags in my 2x7x7 tent and it did nothing. Use more ventilation when the lights are off.
