I'm still trying to find an effective way to create a tropical environment for my Petiolaris complex and other assorted hot and humid types. I'm tossing it around in my mind to redo my fishtank setup, either with that tank or something else more shallow. I'd like to put a bottom layer of clean, rinsed sand, followed by a layer of rines peat, with a good layer of LFS on top. And then I'd place my tropicals into this substrate, without using pots. But how to effectively provide heat without taking up a lot of room with a heater and a jar? Not sure how to resolve this.
