Yes, GG I had heard the rumors too!
It was alll caused by Lowryder 1, that was a mid-level high and a mid-level yield.
I had optimized growing conditions with them too, each was under 150 watt HPS, with 2 waterfarms grown my smaller tent (20" x 36" x 54"), with 3-125 watt cfs (3000 k), one in each corner, and 1 in the middle, then I had 3-85 watt cfls (6500 k) spaced out along the front of the tent. With the smaller size of the tent, the reflectivity was amazing as the branches were beefy everywhere.
Oh, this was the first time I had grown with bloom boosters like koolbloom and overdrive, and a sugar source from Flora Nectar. When I went from koolbloom to Overdrive, I would come home after several hours and the buds changed so dramatically that barely could recognize them. I couldn't go for more than 6-8 hrs without checking on the lights as they grew in a sprint for the lights (2-3 inches).
I feel bad too, as a few years back there was another forum where somebody had claimed a 3 1/2 oz. yield, and some one flamed the guy for b.s, and I back him up. My experience up to that point was 1 auto grow where I got around an ounce a piece off 4 Auto AKs, under 400 watts, but no bloom boosters, and smaller net pots, that didn't allow for the roots needed for the autos to yield well. What a noob I was, you don't slam soneone for doing better unless you've tried it yourself, and under the same growing conditions. So I did and I am hooked on waterfarms, and I am trying out coco, also. potluvr
