maybe not the ABSOLUTE best strains in the world, my my top 3 faves are pretty fucking awesome...
jack's cleaner 2 - touchy feely warm glowing euphoria with a slightly stony edge backed up by real trippiness @ 9 weeks
sweet haze - more fruity and trippy than any haze i've tried yet @ 9 weeks
haze x sunk (HQS) - THE most potent strain i've ever grown. tastes like cigar wrappers, but has real trippiness with motivation and even after a month is no more stony than some lead eye. the buzz is really long lasting too. i lost a lot of weight by accident on it just tuning hunger pangs out and focusing on whatever i was interested in. 12 week strain that will beat you down with room spinning dizzies if you don't respect it's limits. i got a mild case the 1st time i blazed 4 hits of it.
none of these strains are embarrassed by columbian gold as far as i'm concerned and each of their distinctive personalities get a thumbs up from this old school snob who started out spoiled by gold.
