Hey guys, I stated in an earlier thread that I'm switching to tubs, and I wanted to know before I buy the stuff, if I should build my own rack. I'm pretty sure I'm going to get into breeding, so I might as well get a rack. I'm just not sure where to start. Are ther any sites that can explain how to build a quality rack? I'm a little confused on wiring the flexwatt and setting that part up. But if I were to buy a pre made rack, does anyone sell them for under 200?
