You can use femmed seeds to make mama plants & clone them of course it’s just that fems can be more prone to herm out than regular plants. Plus if you made the cross yourself and have a shit-ton of seeds you can potentially find that super special phenotype in the bunch and select her as “mother superior.” I have cloned both reg and fems side by side. As long as the genetics of your femmed strain is relatively stable herms are not a thing to worry about much. Sometimes they can surprise you though; I have found many femmed clones that start poppin bananas by week 9. So you just pinch em off before they open. Not a big deal usually. Finding a selfed seed or two in your buds is not a bad thing; it will be a girl but just be aware the hermaphrodite trait is now baked in. Just watch out for boy flowers late in bloom phase…
