You can keep a mom from a fem seed especially if its a bomb pheno....but I have had zero luck finding a keeper in fems so far....from female seeds and greenhouse...like I said no personal experience with barneys fems just a blue cheese that had already gone thru the selection process I assume because I got it from a good grower, and it turned out well had to clean my scissors like every 5 mins .....like I can't honestly tell you out of a barneys 5 pack the plants will all be uniform phenos.....and I'm pretty sure it was barneys and not a fem but not 100% sure.
