Overkill. I can get a pound from a 3 gallon nursery pot. 5 gallon should be easy. Even for a noob. Simple balanced organic soil and a consistant wet dry cycle will trim and digest your roots for you. Air pots and enzymes are just an expensive way to exploit those who don't know nature does it for you. K.I.S.S.. Dirt, water, food and light are all the plants need. The price or shine on the bottle is irrelevant to the plant. Money doesn't grow plants. Meeting requirements does.
