totally feel you my friend, i grew 5 last time and had all 5 male, its the worst feeling in the world, 3 months of work and time invested for along with electricity and nutes and soil... just for a plant with a cock and balls
There's studies showing that plants "scream" when ripped out of soil, however if asked to be harvested first, there was a MUCH less reaction. I believe this was done with carrots. I'd just tell them that they will be used and this doesn't mean you don't love them. Then use the leaves to make cannabutter or at least add em to a compost pile. I always feel bad ripping/snipping the males out.
