Ive just set up my vivarium 2 days ago. Obviously there are no frogs in it yet. As Im letting the plants take root and the clean up crew to multiply. I have 2 questions. First is how to keep my tank cool without blasting the air conditioning? I have other reptiles that I don't want to get to cold. I had the air on 78 yesterday and the tank temp was 85 at the bottom measured with a heat gun. I know its due to the lights heating up the viv. My top is all glass. I was thinking to get small computer fans to aim at the lights. Not sure if it will help. Any sugestions would be aprichiated.

My second question is humidity. Since the setup my digital guage has been pinned at 99% when I mist it seems the plants never fully dry off and the front of the viv is constantly condensation. I read I should mist twice a day, but this seems to much to me. Am I doing this right or what do I need to adjust?

Again thanks in advance to anyone who takes the time to help.
