I'm with you.
FIM isn't rocket science folks. Use your clean hands and pinch that fucker. Haven't any of you grown roses or tomatoes? It's the same principle. Find the brand new light/bright green growing tip. Then pinch off 3/4 of it with your fingernails. If you don't have nails use a pair of sterilized nail clippers.

Some strains will respond with a lot of tops, some won't. I have one strain that will give me lots of tops, but I sacrifice big colas. I have another strain that will give me lots of tops AND big colas. Other strains will just divide once and call it a day.
