Best headband from seed for me was Underdawg#1 by TopDawg seeds. The sour kush by RP is not headband. I believe Ganja Rebel is the only breeder with available crosses with real Headband clone used, there may be others. Loompa has a real nice Headband but hard to get seeds from Loompa. The sour kush that Reserva called headband for alittle while is great though. From tall sour diesel phenos to more squat sour kushy phenos, all of them out of pack i ran were very sour with hints of either lemon, fuel, or earthy.
