I may be totally off because I've never dealt with a rack of any sort. But I believe there is a serious design flaw here...unless I'm misunderstanding how you intend to set it up.Originally Posted by SnakeySnakeSnake
Are you intending to use ONE piece of flexwatt run across three different tubs of three different sizes? If you have the flexwatt hooked to a t-stat, or whatever instrument you use to control temps, you won't be able to maintain the same temps in each enclosure. The 12qt would heat up a LOT compared to the 41qt. I don't see how you could maintain a consistent, even temp-gradient in each tub with a single heatsource.
