My wife's cousin breeds Rainbow Boas and is giving me a baby once they're born which should be any day now. The past couple of weeks I have been trying to get the terrarium ready as far as temps and humidity goes. Here is a list of my equipment. 55 Gallon Aquarium w/ Plexiglass covering most of it with enough open areas for air flow Ceramic Heat Emitter Large Heatpad Medium Heatpad 2 digital hygrometer/thermometers 1 Zoo Med Hygrotherm 1 fogger I have 2 digital thermometers with one at each end. On the left side I have the fogger with the sensor for the Zoo Med Hygrotherm on the right side. The large heatmat is also on the right side under the tank. Substrate is cypress mulch and sphagnum moss. I have the ceramic heat emitter on the right side as well. Using the only the heatmat I can achieve the following numbers: "Cool side" - 75-78 degrees F, 80% humidity "Hot side" - 78-81 degrees F, 75% humidity When I add the emitter to attempt to raise the "hot side" temps I can get to about 84 degrees F but my humidity drops fast. The fogger stays on all day to try to compensate. I'm trying to achieve at least upper 80s on the hot side but not at the expense of the fast humidity loss. I added the medium heatmat to the right side of the tank and turned off the emitter but it still stays high 70s. I'm at a loss on what to do now. I need to raise the temps about 10 degrees without sacrificing the humidity. I'd be open to any suggestions anyone might have.
