One negative thing I see is the fact that it uses 4" rockwool cubes. 336 x 4" rockwool cubes is going to cost hundreds to fill everytime just in rockwool. Also you are limited to only short strains now unless you do some sort of a circular scrog reducing your plant count. That one looks nice though like the old omega gardens, a lot better than those roto-grows with the built in ballast (in a plastic enclosure?)...that's a fire waiting to happen.
