Sorry….didn’t mean to get all “secret formula” on ya!!!
I used ¾” oak plywood for the enclosure…with solid oak trim to cap things off and create the substrate dams.
As for heating…each enclosure has an Intellitemp heatpad. All four are plugged into an analog T-stat I got from an online dealer. Since I have two BPs and two Corns in there, I balance the temps by adding more substrate to the Corn vivariums.
The BP hotspots hover around 88-92 degrees, while the Corn enclosures stay around 80-84.
I’m building my new one quite a bit different. I’t’s far more substantial in size and construction…but will be heated with the same type of pad. I put a flat sheet of linoleum on the tank ‘floor,’and silicone seal it down. Then I put the heat pads in…and cover them with another sheet of linoleum…which is, again, silicone sealed.
Since I’m going to continue to keep BPs and Corns…I am switching to Herpstat 4s for my T-stats…so I can control each tank individually.
