Like I mentioned in another thread. It's almost summertime and in Vegas IT REALLY Sucks. Last week it jumped to almost 110 and now the temp dropped so I got a little break. I went out and got EcoEarth and put about 3 inches of it all over my terrarium and then I put cypress mulch on one side and added the other side with plants and humidity moss. Tell ya what it really holds in the moisture well. Most of the time its staying in the 70's and even goes in the 90s after i spray down the tank. My tegu loves the dirt though hes digging holes like a well digger and constantly having to change his water dish. But it really keeps him happy. Try it out if your haven humidity problems.
