I recently found out that a 40-gallon terrarium might not be enough for my bearded dragons. I am looking for a 120-gallon terrarium but I have searched everywhere with no luck. Most websites that sell them aren't in business anymore. The ones that are still in business charge an arm and a leg for shipping since it's too far away from me and apparently they are heavy as well. I still haven't crossed it out though since it might be the only way to get one. I was thinking of making one but, to be honest, I am not really good with my hands and I don't want to go cheap on it either. I have tried finding some sort of plan but the ones out there aren't very specific... I was thinking of having them stacked as well since I have 2 bearded dragons. Any help will be appreciated.
This is a walkthrough of building a pretty popular enclosure https://beardies.dreamwidth.org/2145.html I would use a T5 fixture for the UVB light instead of a T8 and I'd use glass instead of plexiglass to fight against scuffing on the doors. I'd also put a vent low on the cool side and high on the hot side and not bother with the back vents. In theory this should allow for a nice crossflow thanks to convection
