Well, I'm struggling for room to keep my feeder breeding colony in my tiny apartment. I do, however, have a utility closet (3'x8') off of my deck that seems like it would be perfect, considering there's nothing in there but my deep freeze. If you were setting up a colony in a space such as this, where the room is insulated but not heated, what steps would you take to ensure success?

I'm thinking:

space heater to raise/regulate the temp. (outside temps range from 38-52 in the winter)
Lights on a timer
Shelving on the walls to accommodate tubs (I've got a GREAT idea for this, will take pics when I'm done)

Anything else you can think of?
