Ok, so soon I'm going to be building a rack for snakes. I know HOW to do it, so don't send me stepbystep instructions on building them because I have those already.
What I'm wondering, is certain specifications.
I've seen some racks with little pins that keep them from sliding out and some without. Are these absolutely necessary?
Also, I was hoping for this rack to be a bp and a corn snake rack, this could be a problem with temps, so does anyone have any ideas to keep the temps down for specific bins? Drilling extra holes maybe?
Would there be a thermostat that exists with more than one temperature setting per plug?

One last thing..
You guys seem to have a lot of luck with Melamine white boards correct? I don't really understand how this works.. do you just buy white boards or do you have to buy the Melamine separately and put it on the boards?
Where do you guys get it? Thanks.
