Need you're opinion on rack idea please

This is a rack i sketched up to start advancing my collection. I'm using Sterilite tubs. The bottom fit's three 28 quart tubs, the middle fits four 16 quart tubs, and the top fits six 6 quart tubs. All of the cubicles have correct height to prevent escapes and a little room on each side of the tubs so they're not jammed in there. Let me know if you think this would be a good setup or if i should try a different style. Also what size flexwatt should i use for each size tub? (i'm opting for underbelly heating) I'm also going to change the inside dividers so as the don't rest on the flexwatt.

Looks good :gj: and if you get more adults, you can build another 3 slot & put on bottom :)

That looks great. My only Hmmm is that we use 42qt tubs for our big females. If you are planning on breeding you can add those on the bottom and continue the step look to the unit with out a problem. We find the 28qt a little cramped for the girls.
