To make femmed seeds, you need to stress a lady. The results of the stress bring-out the self-preservation technique inherent in all strains, (the ability to self-pollinate) thus continuing the strain. This is not to be confused with a natural hermaphrodite that grows-up expressing both sexes.

When a lady is stressed to this point, she'll either pump-out her own pollen, or die trying. This pollen has no donor male chromosomes, and per biology...can olny make female offspring. (femmed seeds) Once stressed and showing nanners, you can either segregate her and let her continue to self-pollinate, or you can carefully collect the pollen, and pollinate other ladies in your growroom. All of the mature seeds will be female. (the tricky part is not pollinating everything in the growroom, so experience and care are necessary)

There are acids, hormones, steroids, heavy metal solutions... that have been used to stress the ladies just to the point of pumping-out the pollen, but I have a big problem with allowing our cannabis seed stock to be bastardized by these gene-altering chemicals and crap. Stress the same seed-stock often enough and hard enough, you'll risk permenantly screwing-up the genes. Breed with those damaged genes, and all future seeds from that stock will risk degradation.

Some techniques risk genetic damage more-so than others, which is why I use (chemical-free) light poisoning most of the time. No genetic damage.

I've heard of many stressing techniques like using temperature extremes (real hot days, real cold nights) or overmaturing to get the same result, but I've never used those techniques in my growroom.
