Critical+ is a fast growing sativa mix indicia . at the begaining it grow fast like all sativa do and towards the end biding time the indicia kicks in that's why it's a fast harvest and it is not a auto flowerCheck out my smoke report! As for light cycle, I did standard 20/4 -> 12/12 in soil. Finished quickly, in like 7-8 weeks. I grew one feminized seed and it gave big, fat colas, and the smell after curing is a very nice spicy-hashy-menthol flavor. The taste is similar, but more floral. A nice even head-body high, but puts me to sleep real easy. I like it, and I'm trying another seed for my next run.
