It's a jungle in here...

My new project involves me making a miniature terrarium jungle. This is a test piece which will give me an idea of what issues I may encounter when I build a much, much larger terrarium for my bigger little house.  The final presentation of this project will be photographs, video and possibly an installation. The problem: I don't have a green thumb. My thumb is very brown - literally and figuratively. Currently all is well, but in this humid, hot Sydney summer I can't figure out how to tame the condensation on the's to hoping the house doesn't turn mouldy.
