I likes a lot! I built a 32 site one in the gray Rubbermaid, but how do you keep the handles from leaking? Silicone? That's what I used, but about 2/3's the way through my grow it started leaking. Oh, and I used mine to clone all the way to maturity in 3" net-pots filled with hydroton. Worked well, but it got real crowded.
