It can't give you more weight. Plants don't transfer up the missing bud. If you cut it. You lose it. The buds may get bigger on top but you can't recover the lost weight.
Scrog is to maximize a 2 dimensional canopy. Fill every square inch with bud. Works great.
But my garden has another foot of bud at the lowers. And it mostly gets nice and dense. And is equally or more potent. I look at cubic space. Way less work than a scrog. And it adds at least an ounce per plant and I am always improving.
Bullshit. Cleaning up shady larf gives me more weight, better quality and I even save time trimming it. Win-win-win!
I think there's a mistake interpretation going on.
Lollipopping in Veg, "potentially", won't have a gain or loss effect on the plant, as the plant has time to recover and grow more leaves. What it would effect is yield/growth vs Speed of metabolism. This is also because personal growing style.
@ttystikk did mentioned Vertical grow method.
Generally speaking, any defoliation (in Veg) will "slow" growth, including training. But this doesn't apply to yield size, just speed.
In Flower it a different story. Hormones change within the plant telling it to stop growth and instead reproduce. Growth never truely stop, as leaves are still growing within the new growth in the Colas.
At this point "any" defoliation will hinder yield. Remember, the leaf's only job is to make G3P, and sucrose.
There's a cell in the phloem called a "Source Cell". After making this Carbohydrates, the Chloroplasts throws it sugars in this cell until Osmosis (vacuum/pressure) carry it down the phloem and into the "Sink Cell" in the roots, for storage and later use.
If you cut "any" leaf, the sucrose production becomes less, and less food to build more plant matter (bud).
Phloem works by transporting carbohydrates by low pressure. Leaves that have the most pressure don't needs these carbs. Buds/Colas, on the other hand, are, because they're new growth. If you cut the lower branches, you are in fact removing "low pressure points" (the popcorn buds), but at a cost.
By removing buds and leaves together, you're removing lower pressure points and carbohydrate factories.
You could argue that since the lower leaves aren't as developed, the lower buds are stealing sugars from the upper growth.
Either way, removing bud sites(new growth) from the "under growth" (popcorn), will increase pressure and the effect of osmosis throughout the plant and potentially increase top bud development. At the same time, removing leaves with never increase osmosis or the production of Carbohydrates.
Defoliation is not a viability means of increasing yield. Selectively pruning buds, may increase top bud size.
