while i TOTALLY agree with you Guwall , i was always curious as to why diff. phenos are found in fem seeds.
had to research in order to find out why. & its my understanding is that fems are still pollenated & variation is the natural way of things
there are several ways to makes fem seeds.
you mention spray... so im thinking the ever popular STS method.
which works like this :
1) several clones of female keeper are rooted
2) a few of those clones are selected & sprayed with "some guys" mixture of STS ...my "guy" is scarhole & he's blessed gudkarma with STS and "the formula"
2a) & a few of those clones are planted placed into veg ... basically made into new (future) "seed moms"
3) it takes a hot minute (30 days ishy) but from those STS sprayed clones males will result. they'll look to stress & drop dead & then come back & reverse
4) now with the right timing in flower (or even just collect & store & break out pollen for a chucka chuck) one of those STS males is used to pollenate the seed moms
5) the result of the stressed female to male (& application of STS) make the pollen absent of the hormone that makes male beans ... just like hermi plants do
6) fem seeds are the result after maturing & ripening ...like any ol seed
i think the same damn thing you do... how the fuck do i get all this variation from fem seeds?
but the fact is... its still a pollenation , its still the combination of plant sperm & plant egg (so to speak) , and variation is natural even if fems seeds are the goal.
surely there are increased "odds" that those S1s are just like the mommy from whence they came... but still its a numbers game on the punnett square.
its how i understand it anyway.
