apical dominance is when the main branches sends suppressive hormones down to the lower or axillary shoots which stops them from growing rapidly. The hormone is called auxinthe purists will say "no" to the stretch..mainly because of management and popcorns at the bottom..they are vine-like and LST actually takes the plants chemical (forgot the name) that's responsible for main cola and disburses it to the other branches which in turn cause them to "turn into" main colas..therefore, you have multiple main colas off one plant..additionally, keeping them shorter and putting netting on keeps the fans below and allow more colas to form..popcorns to fatten as the plant really is growing sideways..although it doesn't look it..keeps the grow closer to a SOG which is desirable.
Auxins are a class of plant hormones as are Gibberellins. They tend to work in pairs, promote/inhibit. If not given something to turn off inhibit, for example,and just given a promoter, the plant will just make more inhibit, to counteract your attempt to promote.
It is somewhat complicated but I have used flower hardeners to make really dense buds.
In fact there are 5 main classes of hormones and all sorts other know plant regulators.

I don't think I want to stop them from stretching. And I don't know of a way to do that.
I get Ozzies per month so I am a Purist, right?
Dropping the light breaks the bulb and damages the plants...Dropping the light stops stretch.
Nice, so you are FIMing from the beginning. Not you. I already know you are.View attachment 3229458
Flippin in about 2 weeks. Top 3 is the white girl, bottom 3 is NLB, ED, and Sour Grapes.
only in Veg hun. Too Close burns em.Dropping the light stops stretch.
i wasn't being critical..it's been my experience that the MEN opt for 18"-24" (which is what i do too based upon everything i've read from the "master growers" here)..case in point is wormie's pic above..see how nice, tight and level canopy is? in the end though, bud is bud and it all smokes..just one scientists opinion.That is not my experience.
These last 2 pairs were a good example. And this is my consistent experience. So, I am sure dropping the light creates More Stretch.
..
The 2 in front had the light down since they were shortish about 26 inches and didn't stretch much so I brought the light down to them
The ones just placed in the back, were under the LOWERED light. They bombed up into the light hood and I've raised it 2 times to keep from burning them.
Lots of myth and lore, we have to do our own experiments to know what is real about it.
i'm jelly on that tent.Sweet tent, too, my Pin.
