Supercropping has a new name, it's called 'The Squish and Push' No messing around, take a pair of regular pliers, pick a spot just above a set of nodes, you can feel how much to squish, try a bit at a time until you know, when you can push it 90* without breaking it, done. I had a streatch Sativa that looked like a crooked cane when she was done, One thing you should do is keep pushing it down, has a tendancy to pop back up too quick. Anytime after too tall is ok to, Squish and Push.

THIS TECHNIQUE DOES NOT DETER THE TOP BUDS FROM FORMING, PLUS A DAM GOOD WAY TO MAKE CLONERS. gb

FIM is just like topping except for you leave 20% of the node instead of taking the whole thing off.
