supercropping

I am new here and would like some help on the idea of supercropping. I don't know when to do it or where on the stem to do it. Can anyone out there help this dirt farmer out?

i love super cropping. i just grab the stem between the 2nd and 3rd node with my thumb and pointer finger. then i apply slight pressure until i feel a tiny snap or hear it, once this happens i squeeze the other sides of the stem and do it once more. within a week you should see where you squeezed swell up like its pregnant. sometimes the stem will remain green, sometimes it gets a nice woody/knot appearance, as well as have a very rock hard feel to it. its very easy and an awesome technique to keep on your mind. i usually do it right before flowering, or during the 1st or second week of flowering.

I do mine the day before the switch to 12/12

this site rocks. thanks for all your help. I will try it in about a week or 2. still in veg for a little while yet. I just wanted to get a game plan for this new crop. always like to try new things.
