I'm in my 7th day of flowering and have a small issue with humidity in my grow room. The room is built in my garage and temp variations are present from night to day. I flower at night in an attempt to minimize the heat that is coming on with spring.
Here' my issue, I never had a humidity problem while vegging, but now that I have introduced Co2 and sealed the room, I average about 80-90% humidity. From what I have read, you need to seal the room, introduce Co2, have plenty of air circulating. I am using the Air-3 Environmental Controller.
I've attached a drawing of the growroom, then also added a few pics, as the drawing is a little manipulated.
So I guess MY QUESTION is, how do I attain and keep constant a lower humidity level?
