I have found in my auto growing that if they get stressed, they stop growing. I transplanted some and one of them completely stopped growing; the others grew a little bit more but not much. The smallest one was fully mature at 3" tall. Had just enough to pack a little bowl.well I had 3 SSHA plants get harvested about 2 weeks ago, their dry weight was only about 2 zips a plant. These were very small as I believe they got stressed and shortened... I have 5 others that should be ready within a week and are 2.5-3x the height of the first 3 and looking quite well.
