What shelving system did you use and where did you buy it?? I've been searching different stores but I'm having trouble finding something with the dimensions that will fit the sterilite tubs.
Also, did you wire for back or belly heat?
It is the 24" Deep $50.00 5 shelf from Home Depot! (in the flooring department) And...I wired it for belly heat with 11" flewatt, I used 11" because all sides of the tubs are exposed!! Its been holding perfect heat and humidity
