I did not know what "landrace" meant so I found this, "
A landrace strain is a strain that is natively bred and grown, like say Highland Thai, Colombian Gold, Punta Roja, Vietnam Black, Hindu Kush etc.... I think it needs to have been around in the area for 50 years before it gets the landrace classification, Old Mother Sativa (originally Mullumbimby Madness) is a strain thats been considered an "australian" landrace, even though its just a pure thai plant, because it has been grown and acclimatised for over 50 years in Aus. When we were being born everything was landrace really, and most landrace were sativa, but now because of the indoor market and the crackdown on smuggling most of the available landrace is indica."
