What techniques would be recommended to keep the humidity up. It has been a real challenge for me as heat sources dry the cage out. Also what would be a good heat source? I had a custom made melamine chondro cage. It had a fluorescent fixture and a heat lamp. I sprayed the cage like a madman and the humidity gauge read in the upper 90's. But in 2 hours it was in the 50's and dropping fast. I want to get back in chondros but I won't consider it until I come up with a reliable way to provide heat and humidity.
