Yea sounds like you have MUCH more research to do lol. Attitude has LOTS of selection. I'd say maybe 60% to maybe even 75% is garbage IMO. Like I said, the breeders here are working with not only proven elite genetics, but the selection they use is some of the best I've seen from most seedbanks like Attitude and the likes. Don't get me wrong though, there are good breeders selling through Attitude and other major seedbanks, but as I said, the selection is overcrowded with a bunch of crap with catchy names.
Landrace Sativas are 100% unhybridized sativa plants that are used to growing outdoors and can reach heights of up to 15 feet. Indoors they wouldn't get THAT big, but they sure will try!
