Bagseed Is Not Feminized

Seeds found in purchased flower are almost always the result of a stressed plant pollinating itself somewhere in the supply chain. Those seeds will mostly grow female, but the parent already proved it would throw pollen under pressure, and that trait tends to carry over. The comparison of bagseed against properly reversed feminized stock on https://queenfeminizedseeds.com explains why the two behave so differently despite both being female. Bagseed is fine for learning, and a poor choice for anything you care about.
