worst strain i've ever grown???? probably the biggest hassle or difficulty i've had was delta 9 labs Mekong haze, low germ rate (20%) and ridiculous flowering time of 18 weeks made it the hardest grow i've ever done indoors. but the smoke is phenomenal long lasting fuzzyheaded feeling with "floaties" where standing still was difficult and made me almost tweakish lol. crossed her to another fem and made some landrace f1's with HGF's super crystal, still haven't grown the offspring.
worst smoke i've ever grown was a critical kush from barney's farm, low odor, low flavour, almost non existent high, lackluster on nearly all fronts.
