There was a guy on the portal years ago that had a grow…..it was basically three bookshelves, repurposed for plant use…set up in a triangle (all on wheels), with the shelves facing inward. Down the center he had two 315w cmh lights, hung at different heights to light all the plants (this contraption was probably seven feet tall)… the plants would get rotated in their shelves a few times a day to get all sides exposed to the big light (supplemental strip lighting in the back)….. and he grew shelves full of little autos…. It was certainly odd and took lotsa fiddling with but he grew a ton of bud in that thing when he filled it up.
