so my 40gallon terranium has an ambient air temp of 81-88 degrees (measured digitaly at center of tank in between hot and cold side), hot side temp under the heat lamp is 85-90, in the dead of summer gets up to 100, but always trying to keep it cooler, its hot here. cool side stays around 80, sumtimes drps to 70, sumtimes gets up to 83 depending on the temp of my room. like i said its very hot here, s its hard to control temps. these numbers sound ok to you guys? humidity is between 50-60% sometimes 70%
