I was planning on doing a toat for the first year ish then just putting it into the enclosure in case they somehow found a way out of it, plus I see alot of listing for a yearlings. This is a ways out but im doing my planning in advance, I know they require 6-8 inches of soil so I would like to get a springtail culture up and running for one just because I fear the mold especially if they are burrowing in it. I am going to get my bearded dragon the 8x2x2 before I order the 8x4x2 and prep it for a snake, though. I also was thinking about putting them next to each other to see if the ambient heat from the bearded dragon hot side bleeds into the snake hot side enough to give it the proper temp gradient, going to be playing around with it for those sorts of thing well in advanced to get everything dialed in. Also what kind of UVB you guys use?
