...I prefer to count a harvest...as one quart glass jar...loosely packed to the top...I don't know what that weighs...I averaged a little over 2 jars..per plant..13 plants..under 400HPS...that's enough to last me..2-3 years..it's only my personal stash...it gets better everyday...I didn't intend to grow so much..I just had more females..than I expected...
