This year i am going to have a 12x20x9 light depo. The plants will be started indoors and hardened off (at first) What is the planting schedule that would allow for maximum harvest (6 is what i hear) i also want to supplement light, should you do this at the begining and end with the light is the weakest or during the middle of the day? Are HID's the best light for this? Light being seen is not a huge concern, but considered. I also was considering digging down 2ft with a raised bed the size of the greenhouse and filling with dirt. Re amend after each harvest. Good idea??? Any reviews on grobot forceflower or other automated systems. Havent been able to find to much solid information, are there any books that pertain to light deprivation. Ant wait to talk about this one.
