Im going with genetics! Nutrients help but its the genetics that really make it. and you got some good ones it seems. I smoked the CC winner G13 Haze. on my last trip to Amsterdam. One of the best smokes we had while there. I am sure its not the same but you cant go wrong with a cross like that. I am guessing it is the G13 male floating around the Amsterdam breeders that was used. but who knows what kind of haze they used for the cross. The high from the stuff I smoke was great. It put a huge perma grin on my face for hours. The flavor was divine, sweet and tropical and with a huge spicy Haze flavor.. make my mouth water just thinking about it.
