Throw them away(not in your own garbage) before they pollenate your females... They dont produce shit worth keeping, and only add to already cramped grow space, so get em outta there when they show, if u r not breeding... That's what u do with them... I prefer to just burn mine in big brush fires way out in the country at friends houses, so they wont continue growing wherever they may be thrown in some woods, which could inturn pollenate someone elses sinsamilla garden, that could and probably is growing nearby... Or, u could kill them and use them in a remote compost pile where their pollen will never reach your females...
