i've run advanced seeds kaya47.
had a mother for about 1.5 years.
very tastey smoke, fruity, easy to grow, good yeild of frosty buds, good to grow into a bush vs SOG, responds to lst, supercrop, fim, not a heavy feeder, likes some calcium, likes proper ph, and zero drama otherwise.
downside : my pheno was a little slow to clone & slow in veg.
imo, the $ of seeds has nothing to do with what you're gonna get vs. your ability to read plants & get the job done.
