Thanks cpw and hulk for your help.

Cpw, wow I did not know that thanks for the link about vdp. That's great information in my case. Since I deal with high Temps and high humidity it seems to naturally work in my favor. 85 degrees and 70% humidity is something I can achieve in my native environment.  Interesting that as heat rises, a higher humidity is beneficial for prime vdp. Most growers demand 76/55. But 85/70 gets the same results with less energy in my case. Thanks again. 

What other advanced sites are your favorites?

Hulk, I tried a dehumidifier but they generate a lot of heat. The night switch is a good idea though. I  will try that. I have plenty of breeze so can't tweak that anymore. Thanks for you help and suggestions.
