I made this set up in a pinch when my girlfriends room mate gave her Russian up to us he is named Hugo. We then rescued a female and named her Olga. This all happened about a year apart from each other. I have always owned Yellow Foots and Red's with a healthy spattering of just about everything in between.
I currently still have my first Boa (sorry Tort people but yes I do love my snakes ) I had him since he was a neonate and now he is 29 years old. So I do understand long term pets. We also have 4 more Boas and One Red foot named Matillda (shes my baby)
But I digress and ramble on so.
I made this in a pinch as I said with everything I needed for under $26. Including labor since it was me

I already had the UV lighting fixture and just needed to replace the bulbs with fresh ones as well as the water bowl. This is really just their winter quarters as in the summer they have free reign of our enclosed balcony (were three stories off the ground but its a walled balcony) which is about 10 foot X 6 foot.
I siliconed the sides of the tank to water proof it (out of habit to my other enclosures) prior to placing the contact paper in it and then I layered a sheet of plastic down before placing the substrate. I let the coconut bark dry out but can get it moist with a few glasses of water when ever need be this way.
Unfortunately I never got around to staining it. though I might do it this weekend since the kids are outdoors anyway.
