It's roughly 48x48x24 and holds 18 - 28qt tubs but there is enough room at the top for another shelf which will allow for three more tubs when the need arises. I am heating it with six strips of 3" - 10watt flexwatt wired into series with a small inline switch worried into each level to allow me to turn off any unused levels. I used 2 stacked CDs on each corner of the tubs for a spacer which I think I will make bigger on my next rack. I currently have the tstat probe taped directly to the flexwatt but I think I'm gonna put a piece of tub between it and the heat tape because I'm settingthe tstat really high to maintain temps. I am using a digital hydrofarm but think I'm going to invest in a Herpstat because te hydrofarm fluctuates a good bit.



Let me have your opinions and suggestions for tweaking it guys.
