How do people keep masses of them in tubs?

[Dr_Gonz0]

Ball pythons don't need supplemental lighting, and in fact, lighting dries up the air, and having no lighting helps to keep the humidity up.

My racks all have belly heat routered into the shelf of each level.

Larger scaled breeders may actually have the rooms temp controlled, rather than the racks themselves (so the room is 85-87 degrees).

Humidity is a breeze to keep up in tubs.

If I ever found myself not keeping the numbers that I have today, and ended up with just one ball python, it would still be kept in a tub, because of the ease of maintaining heat and humidity.

Are your racks made of melamine particle board? If so, bad idea routering a channel for the heat tape. The bare particle board releases formaldehyde gasses when heated which can be toxic in high enough levels.

Greg Graziani talked about it in his recent interview on Reptile Radio. I have heard it a few other places as well.

Just some food for thought ...
