Step 4. has more to do with apical dominace that available light.
Apical dominance in a plant is where vertical growth is dominant over lateral growth.
At the terminal bud (at the apex of the plant) auxins (which are hormones) are produced wich promote verticle growth and retards latral (horizontal) growth.
Bending a plant and making the terminal bud lower results in lower auxin production & so the lower latral growth surges forth.
Suddenly we find that the latral growth become verical growth and there are now many terminal buds all producing auxins further reducing lower latral growth.
In a normal plant that has not been bent or topped, the terminal bud grows upwards and as it gets further away from the lower nodes recieve less auxin retardment and they grow in to side braches.
As much as it might seem logical the because the lower latral growth is reciving more light it spurs thier growth , it is in fact the reduction in auxin levels.
This technique has been used in fruit tree training such as espalier, fan training and step over, which produces higher crop yields as it is the new latral growth where the fruiting buds are to be found.
Another interesting fact about auxins is that this is also the hormone responsible for rooting and why we take cutting where we do.Any young plant want to reach for the light and grow taller than any competing plant around it and it is the auxins that make it do this by making verticle growth the dominant trait.
Love the diagrams blue ,I have seen this done with long lanky sativa strains when grown in a height restricted space
@skrewg, one could almost say - one opinion but multiple tips XD

Not sure on exact size it's probably around 6-7 litre. The issue is if i'm LSTing you need space to tie down, i don't think the one i'm using is big enough circumference wise.
