So I have been thinking about it ever since I caught the BP bug, and found out racks are the best and most economical way to house BP's.
I currently only have 2 female BP's, but I have made steps to change that. I put down a deposit on a pastel, and in talks about acquiring a spider and a mojave.
This is a picture of the rack I have in my mind, I'm more of a visual learner, so I figure if you guys saw it it would be the best way for you guys to help me out.

The number in tub is it's quart size. All the shelf will be the same height, all the Sterilite tubs pretty much are.
I have read over and over that it is best to have 1/3 of the tub over the belly heat, so I figure I will put only 1/3 of the smaller tubs over the flexwatt.
I'm planning on a Herpstat, everyone raves about them on here and I figure I might as well get a good one.
So what do you all think? Am I on the right track?
