I'm trying the double potting method to save horizontal space. I'm keepin them small so I'm gonna try to get away with 1 gallon pots. I cut the bottoms off then tape em back on once they need transplant just fill a fresh bucket with medium and place on top. I'm thinkin you actually gain a few inches of depth, whereas if you go up to a 2- 3 gallon there is lotsof wasted dirt on the sides that the roots don't really use like top 3-4 inches or so?
Just a thought, I'm a noob still.
