Hello, I am in the starting stages of building a huge Custom enclosure to move all my reptiles into one room. Its going to house 2 Ball Pythons, A Boa Constrictor, a Crested Gecko and have a small empty unit on the bottom for a future resident. The three top tiers will be 6' long x 24" wide and 18"tall. Bottom tier will be split, one for the crested and then the empty one. I am struggling with wrapping my head around what to use to heat the top tanks with. There are so many options with RHP and CHE's with a cage. I am not too worried about belly heat, because heating a basking spot will warm the substrate up. I am sealing the inside of all housing areas with Non-Toxic Pond Seal. I will also be using sliding glass doors. I will also be using Vivarium Electronics VE300x2's to monitor the temps. Probably a middle probe at center of each enclosure and hold that temp around 83-85. What do you recommend to use for heating. There are so many threads and groups that just want to argue over what is better, I just want what's best for my animals. I will also have a side box for a misting system for the Crested Gecko and the build has started, but I just want to heat it properly and get my snakes out of glass tanks and into a life home. I think that covers everything I can think of right now. Thanks for you help in this.
