So i was curious what happens when the humidity levels in your grow room are too low during the lighting period. For example i have a when my lights are on the humidity levels are around 16-28 percent and when lights are off its around 40-50 percent. :smokin:
You want that to be the other way around. Figure out how to raise the humidity while lights are on and lower it when lights are off. High humidity during flowering will cause mold to grow in your buds. At 50% you might be ok but 40% or lower will definitely decrease the chances of mold growth.... Don't worry about humidity of you cannot control it while lights are on. As long as the humidity doesn't stay at 50% while lights are off, you will be ok....Quote:

Actually, 50% is just right with lights on or off. I am guessing that you are venting your lights with a strong fan that is also sucking the humidity out of the room at the same time. What are your temps with lights on/off? You may be able to get a timer to control on/off times of your venting. Also if you have good air circulation in the room ( fans ), you won't have to worry about moldy buds with 50% humidity.
