hey, all. in a few months i will most likely be getting a rack.
i have a few questions, though.

1) i see pictures of racks and it looks like there is no circulation. is it okay to drill air holes into the tubs?

2) are hides necessary for racks? i heard you don't need them, but i want to provide what's best for them.

3) heat tape makes more sense to me than using radiant heat panels. what is the advantage?

4) say you have a rack with three levels and two tubs each level. if all six snakes require the same temperatures, is it safe to plug all of the heat into a power expander, and then plug that into, say, a herpstat 1? or is it better to get a herpstat 6 and connect each one individually?

thanks for any replies!
