I built my own using the sprayer manifold from a broken ez cloner. best thing I've ever done. first version wasn't as sweet, because the lid was straight across the top at the point that it attached to the bottom, so water would leak out on the sides and I would have to add water every other day. The solution for version 2.0 was the Rubbermaid roughneck Large size. the lid slope down from the outside rim where it clips on. All of the netpots are below the lid line now, no more leaks. rooted clones in 6-8 days
