I would rather buy Unfeminized seeds, but Greenhouse does not sell them. The reason why I rather do this is because when you create feminized seeds, you stress the female to hermie, usually by flowering her a few weeks longer then she should be. She will develop a male banana. You take the male banana and save the pollen. Then take a flowering female of the same strain, and pollenate her, Because the pollen came from a female that Hermied, The hermie gene has been activated, so you no longer have the same exact genetic makeup of the original strain. Feminized seeds tend to hermie, because that hermie gene was activated.
Regular seeds you might have a 50/50 percent female to male ratio, but you don't have to worry about hermies as much unless they were severely stressed.
But I do buy Feminized seeds, I just wish I could by a regular seeds of White Widow, Or White Rhyno.
