If you are growing indoors and live in an area where you find "ditch weed", you might consider placing your unwanted males out in a patch of "ditch weed. Might improve the genetics a bit. Next year's "ditch weed" wouldn't match your well cared for indor crop in potency, but it ought to improve it a bit! I can forsee a day when breeders will have the large commercial type hemp plants that have a decent THC level. It would be nice if someone found a sex linked trait (some easily seen marker- like red stems or something) so separation could easily be done. There are breeds of chickens like that have traits like that, why not hemp? Think about it-- separating the males out for hemp and the females for smoke! A dual purpose strain. But in the meantime, get rid of your males to improve the wild pot.
