my buddy and I grew greenthumb's MTF. I smoked a fair amount of it way back when. it has a clean citrus-pine taste, really up high, not a stone. One of the hallmarks of this strain is the braided look of the swollen flower bracts which grow one on top of the other and twist into what looks like braids of rope, sort of. You'll know it when you see it for sure. It's unique in appearance.
