There is really no reason whatsoever that fem seed would/should produce less than reg seeds. I would say that you might have gotten a bad batch of seeds. Autos, however, will virtually always produce less and be less potent than fem or reg seeds that are not autos.
Whatever. Ive been growing since 1972. Ive grown seeds from plants Ive had that slightly pollenated themselves, that were good plants, but would neither breed them, nor rely on them. I prefer my mother plants ect to bef from seeds, or from a mother plant grown from seed. Also IMHO they a lot more likely to hermi from stress vs a regular plant from seed.
I totally agree with you on that THGAll living things have recessive genes--that doesn't mean that yield is going to adversely affected. I can assure you that a good grower could grow a non-femmed seed and a femmed seed of the same strain side by side and that you would not be able to tell the difference either in the growth or the quality of the bud.
I personally totally 100% agree with what you had said about that.Fem seeds carry ressessive genes for 1. Ill never use them again, as they were not in the same class as the originals.
