I don't know, that's why I gave you the measurements. Yes, I suck at math.

If I was in your situation I would use a bunch of scrap paper and make a mock-up of all 12 pots, the controller bucket(about the size of a pot) and rez so you can have a good representation of placement and size, then decide for yourself if you'll be able to access everything with relative ease.
The mock-up will obviously only be two-dimensional, but it's really footprint size that you're most concerned with here. Also keep in mind that all the pots aren't supposed to be squeezed together tightly. You want some space between pots, especially if you decide to grow 3-4' plants, which is really what this systems excells at. Ebb & Gro wasn't designed for Sea Of Green grows.
