Scrog requires a screen, and some lst. just a screen of green...I thought LST is low stress training. bending and tying, weighing branches down. usualy no damage.
Now is the above technic that cat mentioned, that simulates a deer chomping off the end of a branch not lst... in order to trick your plant, wouldn't that require a more of a pinch and bend, even looks like its broken? which I believe is suppercropping.
Then there's topping and fiming....
But whatever it its called he's spot on. I love manipulating the plant from the very earliest you can.
When its small (well rooted) you can take the very top nub off, (This does less damage) then cutting the top off.
If you carefully spread the very top set of tiny leaves, and you look for the spot in the middle. a nub (which is the newest growth) to appear. (if develops a stem you can still pop it off, but there"s a chance to break uneven).that will eventually be your first main top. you take a toothpick and pop it off. It comes off easy. Then two braches will grow perfectly. Then when those two grow out, you keep and eye on it, and do it again. two more identical perfect branches. that will give you a symmetrical even plant that if well trained will give you maximum tops. You have to lst and suppercrop but that would give you a perfect even trained canopy.
And the wider your pot the wider your canopy will be. and a long veg period for training will ensure a bigger harvest.
Budm... nice spread of 2 girls... good bunch of tops...
Perfect example of a scrog.
