Just thought of some additional info. I am having a slight humidity problem with summer here. The humidity keeps at around 35 to 55. Mostly in the 40's. every once in a while it gets up around 60 to 70 never more than a couple of hours. I have 1 pu fan on the bottom and a intake about 70cfm for the tops and a clip on fan blowing on the bulb usually around high 70 to low 80's. Constant fluc though. Thanks
