friend of mine grew skunk special from femaleseeds.nl, no probs,

then i gave him 10 seeds, also from femaleseeds, not one of them germed, which i find a bit suspisious, i think hes f*cked them up somhow but blaming the seeds.

im currently growing dutch passion fem skywalkers, no probs yet...

i think stress seems to be the common factor with herms, feminised or not..
keep your environment within the perameters nd you should be good
