@jbclem, here’s an ongoing thread about my irrigation system … http://growingfruit.org/t/irrigation-combobulation
I don’t grow marijuana because (a) I don’t care for the drug, and (b) other vocations in agriculture are more profitable; e.g. fertilizer sales.
In my experience, the blow-molded 25 gallon pots work fine for shrubs and young trees. Being flexible it helps to have a dollie to move them.
