DIY Plywood Cage Question

[CloudtheBoa]

I initially made two 6'x2'x3's (LxWxH), heated with a 120 watt RHP on one end and 100 watt CHE on the other. With a space heater, I didn't really need the CHE anymore, and nowadays I try to put basking areas closer to the panel vs trying to heat all the way to the ground. The cages were originally for my 3.5' bp and 6.5' boa, but the bp was switched out for the retic (7.5'-8.5' while she was in it), and then eventually destroyed when our old trailer was vandalized. I plan on building some new enclosures (hopefully with better planning haha). My bp is very arboreal, and loves to climb, so he benefited from all the space.

I treated with water-based polyurethane, and that worked well for me...I just didn't treat the outside, and that was their downfall when they were left outside in the rain. XD Each individual piece of wood requires a different amount of coats, but the poly is non-toxic once dry and does very well at keeping normal amounts of moisture out. I never tried something like a BRB, but it withstood about 4-5 years of wet EcoEarth and any bowl tippings without damage before the incident that destroyed them.
