16 years of bp ownership and we finally built our final habitats.
My son and I built these ourselves using 4 feet x 2 feet pvc sheets. We put foam insulation on 3 sides and covered them with watered-down grout and dryloc paint. Substrate is a 1-inch layer of clay pebbles on the bottom then put a 4-inch layer of a mixture of coco coir, top soil, and perlite. Temps and humidity are rock steady through the seasons! I'd say we spent around $300 for one habitat (not counting hides and water dish as we already have those).
This here is Jack (14 years old):
And this is his dad, Salazar (16 years old).
Here's Jack's birth story for those interested:
