best i've smoked is hard because some of the best stuff was noname, but you can't go wrong with these if they are grown correctly from the right stock:
green crack
grandaddy
lambsbreath (aka jamacian lambsbread. the REAL shit. trippiest smoke ever)
best i've grown is a bit different because i don't have access to clone only stuff, but some stuff that i was really impressed with:
pineapple chunk, barney's farm (pheno dependent)
mk ultra, THseeds (also pheno dependent)
super lemon haze, greenhouse (got 2 phenos, both were good)
when i say pheno dependent i mean that there are phenos i got that were pure crap. so if you hear anyone bashing on these strains they clearly got the shit pheno(s).
