It's a 30x30x45 tank, two green tree frogs (forgot to mention, sorry), and the humidity is typically around 75-85%. I'm trying out a repti-glo 26w 2.0 compact bulb now, and it hasn't really raised the temp too much, and even dropped the humidity. I don't have any live plants in my tank, just a central driftwood log, a fair sized soaking dish, and two fake jungle plants on opposite sides of the tank.
