Ok here's what my setup for this is going to be, a hybrid soil/hydro. I'll be using a 15 gallon round tote with an organic soil mix consisting of:
organic potting soil, 7 gallons, 1 gallon recycled soil ( for the microbes mostly ), 2 gallons worm castings ( fresh ),2 gallons coco coir, 1 gallon composted cow manure, 2 cups of Growmore Organic Soil builder, 2 cups lime, 1 cup Epsom salts, and 2 cups blood meal. 125 ppms of Cal/mag will be added to every gallon of water.
I will be using an A.I.T. unit, Air Injection Tech. I purchased a 7" unit sometime ago for this. I'm considering making it a bottom watered system also and if so, I'll document it in the grow thread.
