Good points Mr420. Here in MI, where a registered caregiver grows 12 for each of 5 patients, plus 12 for myself. I'm planning to build a grain dryer-like round greenhouse, about 40ft tall X 20ft diameter. Covered with greenhouse plastic, it'll satisfy our"covered on all sides" requirements, plus it's rural setting in my semi wooded lot helps the stealth. A 12-18" diam PVC sewer pipe with 72 holes set vertically in the center of my round GH ensures a 50 ft tall 72 plant mega cannabush that'd have a water lift pump for watering.
. I could do DWC or bubbleponics, since there'd be 72 separate medium chambers. But the daily maintenance needed makes me believe a super soil will produce the easiest and best bud. Plus watering with straight water, allowing nutrients come only from Super soil, with air stones to each plant, makes this a good blueprint for 30-100 lbs at harvest in under 400 sq ft. Plus supplemental lighting on the sides during the early and late part of daylight hrs keeps shade from trees hurting me too much, hopefully. Plus with so few cubic feet, CO2 enrichment would really help & not break my budget.
