I'm pretty sure they pulled a bp out of it, but I have a crappy memory.
I have done research and I know how much everything costs; good thermostats are 200-300, commercial racks are 300-1000+, home made racks are around 100, incubator(home made) up to 300, food and substrate(paper towels/newspaper) depends but I estimated 500 for a year, snakes 2000- 3000.
I can't do anything permanent because I live in an apartment, but the shelves are a good idea.
How is the heated room system sub-standard if people use it with no problems?
I'm probably going to build racks like Wapadi said, but I have no experience with wiring heat tape.
