I need practical information but what I was really looking for is what is the average. You have given me that. Being very near harvest I see some methods will be more productive then mine in product per sq. ft. flowering. I think I can do sea of green by training and get several times the crop, while still needing less headroom. That means that, properly done, I may be able to veg under and flower over, using the same floor space for twice the function. I am planning to try that and to switch from dirt to hydro on my next grow. My containment trays are on risers for drainage purposes, I just have to design a piggy back arrangement that is light-seperate. I will let you know how it works out. I will have a separate drying space because I plan a continuous grow when I get the bugs out, but I have a closet that will do the job. I can keep it fairly light tight and use the humidity controlled air from the grow room with a small duct fan for correct air circulation.
