There great for their purpose, I started mine inside in solo's and put them outside in the ground after a couple weeks, and that was around the middle of April close to 4/20 and they came down about the middle of June. I didn't keep up with my dates exactly but I thought mine finished before the 90 day mark. There great if you depend on an early outdoor crop for smoke or income. Mine lacked on taste and bag appeal, but that could have been error on my part, I amended with Growilla Veg/compost n peat at beginning, did nothing for bloom. What I remember most was the lack of trichs even though it was strong medicine, its been to long for me to describe taste and effect but i wasn't disappointed, not connoisseur but definitely worth growing in my opinion.
