when a plant gets stressed and becomes a hermi, it will polinate itself. and these seeds will be ~90% female and will be a clone practically of its parent, but there is a major downfall to these seeds, they will be more susceptible to becoming a Hermi. for example say your power goes out and your light schedual get messed up... these seeds will hermie on you so fast! feminized seeds are made from hermie plants fyi. feminized seeds will most defiantly always hermie outdoors. in fact they will hermie unless you are growing under near perfect conditions like indoor, thats why feminized seeds say they are only suited for indoor use.
