I have always hesitated using feminized seeds because of the risk of hermaphrodite plants. If they are male thats easy, you can find those early. If a hermi dropps pollen in september, its not going to be good. Could be lots of seed and it would all be worthless.
Here is info on Femenized seeds:
ibechillin said:Nothing wrong with feminized seeds, they are made using STS (Silver Thiosulfate) or CS (colloidal silver) which involves spraying to temporarily make female plants produce male parts through hormonal change. It is not stressful to the plant in any way and the plant goes back to being all female when you stop using the silver spray, it only affects the branches that are sprayed as well not the whole plant, it does not cause the offspring to be hermaphrodite as it is a hormonal change. Regular male x female seeds are just as likely to be hermaphrodite as feminized seeds, its an inherited trait from the parent plants. Through multiple generations of selfing negative effects will surface because of the lack of genetic diversity, outcrossing should not be a problem.
I have found many female individuals that I could not reverse by stress, as well as a few that could not be reversed with STS. Why I do not know for sure.
Selfing to S4 will cause inbreeding loss of vigor and many buried negative genes will be expressed, try for S5 or S6 and you are lucky to get functional pollen Dehiscence, I find sticky pollen that is viable but does not drop, so it is functionally sterile. You can use it with a q-tip if careful. I try to not make above S3's. It is hard to use STS to make all female copies of a female clone specially if a Poly-Multi-Hybrid, a selfed female clone of that type will segregate and act as an F2 population. So very hard to find one just like the clone mother.

you can cross two female or cross two males by transforming one to the opposite sex, a transformed female clone to male will express pollen but it is still genetically a female, the same with males they can be transformed to female to make seeds.
Transforming males to a female will also allowing smoking of the male transformed to female expression or lab testing of the cannabinoids and terpenes they can contribute to progeny.
Regardless if the female is Haze or Skunk the f1 hybrids express the same general terpene and Cannabinoids, I have made hundreds and tested them.
There may be sex linked traits but this has not been proven in Cannabis.
Intersexed plants can be male or female. Males that are intersex can make seeds on themselves or on nearby plants.
One last point is plants do not just turn intersex because they have not been pollinated, they are born with the intersex traits, be they XY intersex or intersex traits that require stress of some sort to express the intersex. Both are inherited from intersex parents.
People confuse dominate and recessive genes with what a plant recieves from the parents, but do a prunett square with two palnts that have dominate and recessive genes for the same gene and you will see progeny have a crap shoot on what they receive. Depending on what the parents have Ww X Rr for example in the case of White and Red.
Plant genetics like Cannabis can be confusing as Cannabis is a dioecious obligate outcrosser and is a bit special. (90% of all flowering plants on earth have both sex, the remaining 10 percent have unisexual male and female flowers on the same plant (monoecious species) or male and female flowers on separate plants (dioecious species) they are the minority. Cannabis is one of the minority it is dioecious.
