Hey good on ya, racks are not a bad way to go. The problem with your humidity in your tank can be alleviated with proper insulation of the screen top. You need to have about 75-85% of it covered with a sheet of plastic and then a sheet of foil. You only need to leave enough room for air to get in and for your heat lamp (if youre using one) to sit on. Heat lamps are another big issue as to why you might have humidity issues. Just sit here and use the search function and look up humidity, tanks. Youll get so many threads its not even funny. It is a common problem.
On the other hand, if you think a rack/tub set up is what you need, go for it dude. BPs like to hide and in a display youre going to have to decorate for the display of it more than the BP of it...BPs are low maintenance...2 hides, a water bowl and some substrate...some f00dz and they love life. And yes, tubs do tend to be a LOT better at maintaining humidity.
Whatever you do good luck and enjoy. Careful...BPs....once you start you cant stop. See my signature? It all started with one rescue....in MAY. LOL

Of course I'm using a heat lamp! What would I be if I didn't. I don't want her to go cold now! I've been using a blanket, which is doing a better job then nothing... But I think I'm going to do the tubs, decorate them and just make them a little more eye catching then I've seen peoples. It peeves me on what substrates are used and not used... etc. I just think, ya even though they don't need much, they are a pet and just like you would a dog, give them stuff and make things look nice for them. I absolutely love my BP, and she's the nicest and most beautiful damned thing I've ever owned. I'm def. a snake person.

I'm already starting my search for the next BP.... I know I want at least four... I know I'm going to go over that one day... lmao. I'm thinking Hypo Mojave... But there are soo many combinations that are absolutely amazing like the Ghost Butter Bee! Just wow. And omg... I rescued my BP, too! And ... I believe in May, too!
