You may also consider these, I've got one and it works great. I just harvested one plant which will generate about 2.5 ounces (still drying). I trained it heavily; I fimed, then LST, and then super cropped. So you spread the canopy out, you'll generate twice as much as if you didn't do anything. That plant was 24x24x20h. If you're set on two totes you may consider making both into one, and open face them together. https://www.amazon.com/dp/B09G2DZ2YF
