I was skeptical but I have seen grow logs for almost all of these products and they were pulling aroound the same numbers as my calculation if not more.

Plant numbers does relate to yield but you do need to have light to match it. I think if I follow the rule of 40w per square foot on a vertical setup just as you would with a flat setup. The plants will be getting light of the entire cola instead of just the top of it and hopefull produce more.

I havnt built a small scale model yet but after doing some calculation I believe I can get 500 plants in a 7ft. diameter 7ft. tall cylinder gow roomn and still provide 6" square for each plant just as you would in any SOG setup.

With 500 plants I am estimating around 1 oz. per plant and get a yield of 30 pounds every 6 weeks in a 10x10 room
