super silver haze : classic,all around sat dom...nice peppry/incense smell and taste...an oldie goldie..decent yields..10+ weeks flowering
green crack : mango taste,gets its name for a reason..very good yields..
peeking out windows :
ghost train haze : by rare dankness...extremely potent,long flowering but not overly..was HT "most potent in the world for like 2 years straight"... good stuff...also by R.D...somali taxi ride....how would it feel to be in a random taxi in a failed state like somalia..
