The best I have ever done under a 600 is 608 grams of dried bud. Which translates to about 21.7 oz. This was for 12 plants for an average yield of 1.8 oz per plant. The plants were 6 each Mandala #1 and 6 each Satori. Would I have gotten more yield from 10 plants or 8 plants? I don"t know the answer to that question. All I do know is I did the very best my knowledge allowed me to do. I do know there are a few growers out there that can do better but there are a hell of a lot of others can not.
