Yep, the GC (sorry, "Dream Queen" lol) I had for about a year was 8-9 weeks, meaning I could get away with 8 but 9 was better, in 6" rockwool on flood n drain tables. Dunno about the others, but I'd expect 9-10 wks on em. GC was one of the earlier finishers outdoors, but I dont think it likes to be outside, it seems to be a better indo than outdo strain in my experience.
