I honestly haven't kept track of the first to chops weight.the lady I chopped tonight I will weigh out when I jar her up.I'll update how much but I'll tell you they yield great.just so you know I have the p450 and the p150 in my 4x4 my buddy has 2 of the p4xml2 with the crees I think I'm getting one of those from platinum soon. I can say from switching over from hps I assumed losing weigh for gaining quality.im definitely happy with my end productYo Man! Great Journal and great Grow. This grow convinced me to get the p450. Any updates on what your gpw was? total weight?
