Usually 200 per unit. I get pretty anal about what my finished product looks like thats why i pay by the hour, id rather people take a little extra time and get every leaf, other then zipping through it and carving the shit out of my buds
It would be a different story if i had to harvest 50-100 pounds, then id be paying peeps by weight
I'm picky too. If they don't do it right I deduct pay. I hate leaf stems left on.
