Just to update, finished the sour crack a couple of weeks ago and achieved just over 3oz of top quality weed.
What impressed me was the actual density of the buds and the amount of trichomes when compared to the old ms0006.
The buds are rock solid and you can tell just by holding in the palm that there is a vast difference over the buds from the ms. By no means am I saying that the ms does not produce good buds..it does ...but nothing compared to the hs1..it's as good as anything I've grown under a hps and the penetration of light lower down was equally impressive.
What was really impressive is that I have achieved over 1gpw for the first time with a led light (and with just 75w!) in 3 years of using them.
Thinking back now, I 've roughly calculated that I probably only ever achieved below 0.4gpw with the ms0006 so the hs1 is a major and gigantic leap ahead.
Still a believer
