I have to grow in pots because our garden space is used for other plants. I was wondering if the pot shape makes a difference. This year I grew in 3 gallon pots, but next year I plan to grow in bigger ones. I have two options available to me, 15 gallon and taller pots, or 55 gallon barel cut in half. I guess my question is does it make a difference if the pot is tall or wide
