Is 5 gallon bucket enough?

From what I was told by an experianced grower a few years ago, was that marijuana likes a wider range rather than a deeper range for root growth. So if possible I would make a 3x3 square and go about a foot deep.

go deeper than a foot....18" bare minumum..!

I read also that they have a wider root base. I wonder how they compare with Blue Berries? Blue Berries have shallow roots so you need a wide container to grow them. Smart Pots make some wie ones I believe. Definitely don't skimp below. A small pot is like bad shoes too small for your feet you got on sale. Yeah you saved money but you don't feel so good. Go out and get a pair of sneakers 2 sizes too small then go to the hardware store to pick out a planter and imagine you are a MJ plant.
