I have read about this strange phenomenon all over the internet, and am giving it a try with 3 spikes from one of my phals.
As I understand it, you cut the spike after the last bud has bloomed, and put it in a glass of water. Then you stick it in a dark room, and then if you're lucky the dormant nodes produce keikis. Some people put Super Thrive in the water, but most seem to just stick in in there and forget about it for a few weeks.
I'm going to take pics as I go, in case this actually works. Any one else up for joining me on this experiment?
