Ok George Lenard......talk about not having a clue. Jamaican herb tops out at 8% THC where as humbolt county herb tops out at 20% THC. Jamaica might have decent conditions but they don't have the genetics. They might tout choc thunder, pineapple and skunk varieties but the truth is its all lambsbread. The best thing Ja herb has going for it is price and being grown organicly. George , I have a clue, you obviously don't.
