I posted the same thing in the ball python section, but hopefully I wont get bashed for doing the same here.

Tubs;
What sizes for each "age group"/How often do you who use tubs/racks switch your snakes from tub to tub?
What type of tub do you reccomend? (Transparent, blacked-out, other?)

Materials & Heating;
What is the best material for the rack itself to be made out of?
Depending on the kind of rack (I'm pretty sure there is more then 1 kind/model right?) how would I heat the rack?
What type of thermostat would I need to get?

Cleaning;
Besides cleaning the individual tubs, would I need to clean the spaces where the tubs are placed?

Bedding;
Any bedding will do, right?
Besides pine and cedar products. Any reccomendations?

Water bowls;
Deli cups with reinforcement?

Any information you can give me ontop of this will be greatly appreciated
