I grow my NL99 indoors, but I have stuck them outside while working on my cabinet, and they weren't sun-shy ... I think they will do well outside ... being a sativa/indica cross, they should stay around 3 foot tall indoors, maybe more outdoors, I just dont know ... I wont know how it smokes until July ... I researched the strain thoroughly, prior to buying ... all reports from experienced growers claimed the Cinderella 99 was pretty much the most potent sativa around, and the ones that rated it at #2 were inexperienced growers that did everything wrong, and still said it kicked ass ... the Northern Lights influence helps yield, and mellows that racy C99 high a bit ... we should be very happy with it ... the NL99 is a great grower, branchy, buds everywhere, very hardy, breeder claims almost impossible to hermie ... its impressive, you'll see what I mean ... whats wild, is when it starts popping female flowers after 60 days, while still in veg ... that blew my mind ... :smokin:
