Feminized plants dont carry the Y chromosome, and are not as diverse as regular seeds.
Ive grown at least 10 different feminized strains, and compared them to both elite clone only strains, and plants/clones Ive obtaind by pheno hunting from regular seeds. Ive never found the feminized seeds to be as good as the regulars, or the original clones.
I reversed an original Chem91skva clone, and while the weed was good, much of it was different that the original clone, and none of it was as potent as the original clone.
I also tried the Barneys Garm feminizeeed G13 x Haze, and I have a clone from 10-11 years ago, before they went straight feminized. Now theyve staarted reguars again, but I grew 20 feminized G13 x Haze, and not one of them was as potent, grew as fast, or even had the same coloring as my 10 years old clone.
Ive also got an original cut of OG Kush, and had the same outcome of the Chem91skva clone. While there was some good weed/plants, not one of them was as good as the original cut.
Also when Ive grow the feminized seeds, I used no less than 10 females to compare.
I also F2 2 packs of Mr Nice Super Silver Haze 10 years ago, and pheno hunted out of 250 females to find the one that suited my criteria. Ive had this clone for almost 10 years.
Ive got about 15 mother plants, some going back to 2002. AK47, NL5, Willie Nelson, NL5 x Haze, Sensi Hashplant, Sensi NL5 x Haze and some others.
I then bought 1 pack each of SSH from 3 different sources of Feminized SSH seeds. Growers Choice Seeds, The Seed Depot, Greenhouse Seeds. None of them grew as fast, were as potent, or produced as much.
Others miles may vary, but from the strains Ive compared to the original clones, or pheno hunted through regular seeds, when it comes down to it, the feminized didnt stack up vs the originals. This is my experience. Others may have different experiences.
Im not sold on feminized seeds at all. Also theyre more likely to hermi.
