In fact it has become difficult to find totes that are larger than 10 gal but still no deeper than 12-13 inches. From what I understand, people use these to store things in, weird but true. A tote that is not so deep has its gallons distributed in length and width which is good because it gives plants more room between them. I recently found a 15 gal tote that is only 12 deep and I had been searching for one.
