What's the easiest and most discreet way to trash males?

I'm dissapointed that all of the healthier ones were male instead of female. Bastards.

Oh well, all of them were from mid bag seed except for one. The one seed is from a bag of grapefruit smelling bud I had awhile ago. Lucky me, eh?

Haha, next time it's all going to be from a seed bank.
