This is from another thread where DHF does recommend stripping a plant after stretch only he does it slow over a few days I guess you chose to only show those threads where he says striping a big plant at once can slow it down you missed the ones where he says to do it slowly this was 3 months ago so obviously he figured it out and recommends it so all those quotes from DHF are only half the story this is what he had to say near the bottom.https://www.icmag.com/ic/showthread.php?t=241158&page=5
"There`s a distinct difference between genetically bred purple strains like Heath did with Balck Russian and Purple Shiva Skunk for the pheno`s that came about as the Black Rose.......and.....
Plants that`s color up with lower lights off temps that kill chlorophyll in late flower and exhibit underlying "anthocyanin" production that`s inherent in all pot plants to a certain degree...but....
Looks like the Black Rhino`s gonna be a green pheno if there`s already budset and no colors are jumpin out..... but....there`s still time to see changes.....and....
It ain`t over till the fat lady sings Bro , so hang in there with the killer work..and.....Once stretch is completely over.....
Start takin off all the fanleaves that have a stem ..gradually over a several day period so as not to shock the plants...but...
Keep doin so till the only 1`s left on em are the 1 leafer`s juttin out the colas till end of cycle and it`ll make yas happy........
Keep on dialin Ismoke....Good luck and....

My plants came from my buddie who thru two extra clones hidden in his outdoor garden so they got little light and had started flowering I thought I'd dig them up because it was going to freeze within a couple of weeks or less and they are under a foot tall with no branching and just some budding hairs they wouldn't have produced anything. I dug them up at the end of september with a big root ball for such small plants put them in 5 gallon containers with only 4 gallons total a gallon of it was shit garden soil they came with that made there leaves yellow They were growing slow with a 400 watt hps the capacitor just died on me a couple of weeks ago thats why the leaves were turning to the CFL's the HPS wasn't giving good light so for the last two weeks they were under CFLS and would have been spindly without defoliation.
Before any trimming this is what they looked like

Naked for the first time.

They were striped twice before these pictures

Then stripped again

Then 70 hours later all the leaf mass is backhttps://www.icmag.com/ic/picture.php?albumid=40230&pictureid=952863View Image
They are much bigger now a week ago I striped them again probably for the last time till after stretch as DHF recommends among others I haven't uploaded the pics yet.
My buddy just harvested the plants they aren't big yielders and his finished plants averaged not much bigger than mine are now actually one was smaller even though he is running hydro so not much stretch in this bagseed strain although the buzz and stickyness are good. I wasn't planing to grow anything so these were a surprise I had a 400 hps I got from work it was a old yard light for one day when I would grow again.
These aren't the biggest or fastest plants but you can see they have much more structure and branching then they would have without defoliation that it what I know from growing for way more than a decade but haven't in almost a decade so some rust is showing but these will produce more than my buddys hydro setup did.
I've have purple stems from cold nights and claws from to much nitrogen low humidity or too much water probably all, and now I've had them on a 1000mh and I put them to close they seem to have slowed down from being surrounded by CFLs which were warmer in a cabinet because the fan I have under the lamp is to strong for an open basement room I have to build a small room to dial everything in it's cold and dry in my basement.
Whodar the last grape study you posted at the bottom said one of the grape variety's did produce bigger taster grapes when defoliated and all the studies did it at flowering time the wrong timing it is best done early and using a plant that grows more like pot would be good sunflowers have one big seed pod and a few leaves you take them at flowering it's to late same with the grapes and soy.
Here Is a study Compensatory growth responses to defoliation and light availability in two native Mexican woody plant species
http://journals.cambridge.org/actio...2316&fulltextType=RA&fileId=S0266467409990514
Defoliation, often caused by herbivory, is a common cause of biomass loss for plants that can affect current and future growth and reproduction. There are three models that predict contrasting compensatory growth responses of plants to herbivory and resource availability: (1) Growth rate model, (2) Compensatory continuum hypothesis and (3) Limiting resource model. The predictions of these three models were tested on the tree Brosimum alicastrum and the liana Vitis tiliifolia. Seedlings were subjected to three levels of experimental defoliation (0%, 50% and 90% leaf removal) along a light resource gradient (1%, 9% and 65% of full sun). In both species, defoliation significantly increased leaf production rate and relative growth rate of leaf area, but not of biomass. Net assimilation rate was the strongest driver of biomass growth in both species, but leaf area ratio and specific leaf area were also important in B. alicastrum. Compensatory responses of leaf area growth in B. alicastrum were significantly greater in higher than lower light availability, consistent with the compensatory continuum hypothesis predictions, but in contrast to the growth rate model predictions. The limiting resource model offered an explanation for all possible experimental outcomes by directly considering the effects of environmental differences in resource availability.

Effects of Artificial Defoliation (Simulating Pest Damage) on Varieties of Upland Rice
W. E. Taylora1
a1 Njala University College, University of Sierra Leone, P. M. B. Freetown
Abstract
Artificial defoliation was used to simulate grazing by cutting-grass or cane-rat (Thryonomys swinderianus), on three rices with durations of 110–115, 130–135 and 140–145 days respectively, defoliated before, during and soon after tillering by removing leaves to half, two-thirds and the total height of the plants. All varieties showed marked compensatory growth, resulting in increased tillering and yield, especially when defoliated during tillering, but yield fell when foliage was removed after tillering, especially with shorter duration rice. Defoliation to half the height of the plant during tillering had the most beneficial effect, whereas removal of all leaves to soil level after the tillering stage had the most adverse effect.

Abstract
In this study, different levels of defoliation were imposed on a determinate species (maize) and a relatively indeterminate species (cotton). The aim was to quantify the effects of defoliation on plant growth and production, under either optimum or water-stressed conditions. Under well-watered conditions, 33% defoliation twice (conducted 28 and 35 days after emergence) resulted in a 16% reduction in grain yield of maize while 67% defoliation once (conducted 28 days after emergence) had no significant effect on yield. Under water stress, the grain yields of maize plants with 33% (twice) and 67% defoliation were 13.5% and 25% greater than that of non-defoliated control plants, respectively. For cotton, the reproductive yields (seed and lint) with 33% and 67% defoliation (conducted 43 days after emergence) were reduced, under well-watered conditions, by 28% and 37% of that of the non-defoliated control, respectively. Defoliated cotton plants lost less fruiting forms (squares and young bolls) than non-defoliated plants during water stress. Therefore, under water stress the harvestable product of cotton plants with 67% defoliation was double that of non-defoliated control plants. In non-defoliated cotton plants, a second flush of flowering after release from water-stress permitted further compensatory fruit set and boll harvest. Defoliated plants did not show such levels of compensation. Defoliation significantly reduced water use by maize and cotton. The relative yield advantage of defoliated plants under water-stress conditions can be attributed to defoliation-induced improvement in water status as reflected in measures of photosynthetic rate and stomatal conductance. Under anticipated drought stress, defoliation could be an important management practice to reduce drought-induced yield decrease, but this needs to be tested under field conditions.

Defoliation studies in hybrid maize: II. Dry-matter accumulation, LAI, silking and yield components*
R. P. Singha1 and K. P. P. Naira1
a1 Department of Agronomy, G. B. Pant University of Agriculture and Technology, Pantnagar, India
SUMMARY
Data are presented from an experiment made in two crop seasons, to examine the effects of plant density and degree of defoliation at different stages of growth in maize at Pantnagar, India, on the dry-matter accumulation in different plant parts, leaf area index (LAI), time of silking and grain yield components.
Different patterns of dry-matter accumulation in various plant parts was observed. Silking was delayed by increasing plant density. Defoliation (even partial) at the 16th fully expanded leaf stage resulted in substantial reduction in LAI and such yield components as number of ears, ear length, ear diameter and 1000-grain weight. On the other hand, partial defoliation done at the 10th fully expanded leaf stage to simulate an ‘erectophile canopy’ led to yield increases even under high plant density (90000 plants/ha) in the Kharif (rainy season), mainly through an increase in number of ears, 1000-grain weight and grain to stover ratio coupled with a reduction in barrenness and percentage of lodging. It is suggested that an increase in the photosynthetic efficiency per unit area of leaf resulting from the ‘erectophile canopy’ is the reason for these effects.

You guys can joke hate or do whatever you want Quote this or that like you have been for a very long time until you have tried it a couple of times like any other training method supercroping lsting topping FIM you don't know anything you have an opinion on something you have never tried.
I'm sure it would work with many crops if done early and tested as some have done for the right time and amount, just like I'm testing it now more than I had in the past and maybe the formula described isn't the best timing I'll test it myself and next run experiment more I'm sure I will be getting more bud doing it as I and many have done it and found it worked.
Let the hate begin LOL.
So these study showing that it does work if done at the right times DOES improve yields don't mean any thing compared to your unfounded theory.
This does work, more testing is needed to find the best ways to make use of this pruning method but closed minds won't be the ones expanding there knowledge.
