seems like all growers would drool for those numbers.....I mean realistically your total amount of wattage will dictate for the most part your yields indoors and how much space you have to work with. are you talking about outdoors?? SOG is generally an indoor only method that maximizes space and time with actually lower yields per plant yet more plants so total yields are reached by using space the most efficiently in small spaces. The addition of a screen is SCROG or Screen of Green similiar to SOG yet still different. as the other user mentioned.....do some google work and you will have more info then you probably can use or even can process...its endless out there on how you can set things up...to each his own and may happiness be found at the end of the day!!! peace!!
