I am looking for suggestions on how to best provide the proper temp gradient for my bp tanks. They are each in 20 gallon long aquariums and they have a UTH on one side. The problem is two-fold. First, although the floor temp on the warm side is about 89 degrees, the temp under the hide is considerably more (based on readings from a temp gun). Secondly, the cool side is much too cool – sometimes getting as low as the mid 60s.
I need a way to provide the proper temps consistently. There is not much I can do about ambient temps in the room and I would like to avoid heat lamps if possible. I am considering flex watt heat tape for the cool side and a rheostat to be able to manually turn down temps. Keep in mind I have 4 snakes and would like to keep the cost as reasonable as possible. (I am saving up for PVC enclosures and plan to use radiant heat panels and thermostats but it will still be awhile until I have my dream snake habitats!)
