My new orchidarium...take a look

[jonnygreenthumb]

OK i cant get the temp lower than around 78dg. at night. I have tried to stop the warm air humidifier and kept the cool air humidifier going on full air speed at night and opened the top half were the lighting is located and put a fan blowing air into the bottom half. Any ideas on how to lower the temp to around 68dg at night?
I will be adding a misting system hopefully soon, my Carpet Chameleon will benefit from that to.
On the idea of taking out the warm/cold air humidifier and using a air duct I would probably have to run it through the top half through the lighting therefor heating the humidity even more. The duct could also run through the side making the duct pretty long. Wouldn't that prevent the warm/cool air humidity from entering the orchidarium properly ideas?
