Whether or not your garden will benefit from LST is a function of your overall space - width and height - and your lights. If you've got tons of space and a super strong light, it's not so useful. If you have limited space, the point of LST is to force a flatter canopy on the plant than would develop naturally. To really understand it, you have to grow a plant out without doing anything to it. You have to look at it every day and see that the bottom 1/3 of the plant is kinda weak looking. You have to see that the top of the plant is kind of shaped like a pointy paintbrush, that the top 1/3 of it is heavy with buds, and the middle 1/3 of it is somewhere inbetween the useless stuff at the bottom and the good stuff at the top. Then, you realize if you tugged the taller canes apart some, more light gets in to that middle third of the plant. Then, you might realize if the taller canes were more wiggly shaped and less straight, then those middle buds would be at about the same height as the tall ones (from the ground). Then, you start thinking if you could force it like that as it grew, you'd have like twice as much plant at the same height getting the really good light. THEN all of a sudden LST makes sense to you.
In this group of plants, I had 3 that were really outgrowing the other 3. Eventually, they would have been so much taller that the others would have been in constant shadow. I gently pulled the central stem over, giving it a 90 degree elbow, and tied it there. Few hours later, the top was once again pointing straight up. A few days later, I repeated this - bending the top over and waiting on it to straighten up. Now, the main stem of those plants is kind of spiraling around the outer edge of the pot, and the smaller stems are sticking up at about the same level as the main cola is. It's hard to see the green velcro ribbons I use to tie the plants down with, but if you look closely, they're in there.
Atrain's picture makes more sense than actual plants.
