My Earthboxes have a 3 gallon reservoir and 15 gallon upper potting mix chamber. Also I have 11- 7gallon pots with tall healthy (well 10 are healthy) plants in them. That one guy got too much water because of proximity to a neihhbor's sprinkler, but I moved him and we'll see if he snaps out of it!
I still would only put one plant in a 12 gallon, but it's going to be a very happy plant.
