I am just about to start the last part of my home made rack. It is a 5 tub rack (Tub Dimensions: 16 1/8"W x 24 3/16"L x 6 5/16"H) rack is made from particle board coated with melamine. and i have a 16in. strip of 4in. flexwatt on each level of the rack. And I need a thermostat and i was just wondering how well the ReptiTemp500R would work. how well it can keep multiple flexwatt strips(three to five 4in. strips) at the preferred temp. I would appreciate the help. thank you!!!!!!
