I know you didn't ask me, but its my favorite thing to talk about as of current.

To me LST is when you bend the plant to grow as vert as you can. Directing its growth to the empty areas of the pot, and controlling the side stems that will eventually become your colas when you ease up with bondage and start flowering.

When most people think of LST its about bending the plant down, sometimes Tying it to itself. If you let the plant grow vertical, each side branch that will EXPLODE in growth may also need to be trained, in order to keep things even, and keep the hormones (auxins?) from regulating growth.
