I've built a 18x18x24 cage of plywood (hardwood) and acrylic with a screen opening at the top. I built this enclosure in the intension of housing a couple of crested geckos. My question is, does this type of enclosure sound alright for them? I'm not using pine, i'm using "hardwood" plywood. And if so, i've got poly already on the wood, but is there anything else i need to apply, since these type geckos require humidity levels of 70%, i don't want the moisture to ruin the setup. Thanks for the help.
