I am building a 4'L by 2'W by 3'H enclosure for my bearded dragon (based on the famous melamine crossfire build). So far I have one vent high on the left wall (hot side) and one vent low on the right wall (cool side). The vents are each 16" by 8". I have a solid ceiling, no mesh top, and I'm wondering if there's enough ventilation. If not, could I get away with just making the vents bigger on the left and right walls, or possibly add another vent on the ceiling? I feel like I'm gonna be pushing this enclosure against a wall, thus defeating the purpose of any vents on the backboard.
Thoughts?
Edit: And do the beams that run along the top and bottom of the front frame (alongside the runner tracks for the sliding panel doors) serve a structural purpose, or merely a cosmetic one?
Those are nice big vents. The temperature differences should pull cool air in through the lower vent and that should work very well I'd imagine. That is how I have the vents on my design, no back vents.
The beams across the front in the versions I've seen are probably cosmetic to hide the tracks a bit. I prefer a drop down door to a sliding door anyway. A drop down with a latch on top and hinges that have some spring to them to keep it from dropping quickly and breaking the glass. That's cosmetic and a personal preference though.
