I grow in a mini sog - perpetual garden with a 2 x 4 ft flower area. I have one 2 x 2 area for moms and another 2 x 2 ft area for cloning and veg. In my flower area i have three trays, i harvest one and a half trays every 28 days. The plants are grown in 16 oz cups, filled with a mixture of mainly perlite with some potting soil. The cups are put up to 12 in a tray and the trays are filled with nutrient solution up to a depth of about an inch. An air wand sits in each tray to provide aeration. I have been using BC Technoflora 3 Part ferts.
