No, they use a steel bladed tumbler. It's like a fucking lawn mower though, JESUS does it produce more trim than bud lol! Then they make US actually finish off the tumbled buds, and it's so dry that you can just pick off the crows feet and leaves sticking out with your gloves. It's REALLY dry. They don't know how to dry cannabis here. One of the field offices was turned into a drying room just because there was no place to put plants, and they stuck fans directly on like a TON of it, so it just dried super fast.
There's some conflicting ideas between the growers here too. Everyone knows best, I guess. lol!
