Surprisingly uniform yields. Slight differences in trim and sticks could account for the differences..
All 4 cans of bud, 1 gallon can per plant, have balanced at 62% RH so its time to see who was right with their predictions.

Clone 1 = 140 grams
Clone 1 had no defoliation and lots of larf low in the canopy.
.
clone 2 = 142 grams
This plant was lollipop but only had a minor variance in weight.
.
Clone 3 = 138 grams
I was hoping for 160-180 grams from this one but it was my lowest weight. Lollipop and swchaze.
.
Clone 4 = 149 grams
The heaviest plant by a hair. Lollipop and 2 swchaze.

I think that we can say that defoliation does't add weight but I'm going to do it anyway because I'm comfortable with the method.

I think that there are a huge amount of variables involved in the defoliation vs no defoliation debate. I don't believe that simply removing leaves is helpful to any plant that has plenty of light or more importantly good light penetration, but it could be helpful in situations where light penetration is limited for whatever reason.Saw this article posted at another site and thought some of you would like to take a look at the finding of this side by side. I have a feeling it's going to get a bunch of members on roll it up butt hurt with the findings...rofl
Let the excuses of why this is flawed begin...lolSummary of Cannabis Defoliation Side-by-Side Experiment | Grow Weed Easy
by Nebula Haze The results are in! Have you ever heard of the cannabis flowering stage defoliation technique? It involves strategically removing leaves when the buds are first forming on marijuana plants. The goal is to expose buds to plenty of light and air, which seems to increase overall...www.growweedeasy.com
Pretty sure they stated some of what you said in the article.I think that there are a huge amount of variables involved in the defoliation vs no defoliation debate. I don't believe that simply removing leaves is helpful to any plant that has plenty of light or more importantly good light penetration, but it could be helpful in situations where light penetration is limited for whatever reason.
Take a look at how close together the plants are growing in the side-by-side linked above, there is very little to no light getting beyond the canopy of the budding plants pictured in that trail. I would never grow my plants that close together and I don't know that most people would, so it doesn't actually surprise me that they came up with those results. The light penetration in a setup like that is shit you would have to remove leaves if you want light to get beyond the first few inches.
So if you grow in a similar way as in that side-by-side trial as far as spacing then defoliation could be a helpful tool to achieve the light penetration levels required to grow weed well. But if you grow with more spacing and plenty light penetration then defoliation is not helpful in my opinion, I think it all comes down to your particular growing method. Indoor vs outdoor is a big variable in this discussion as well, as it has to do with light penetration. Indoor lighting quantity/penetration changes drastically based on the distance from the light, whereas outdoor this is not the case at all.
So in conclusion sometimes defoliation can be helpful and sometimes you wont see a benefit depending on how you are growing, sometimes it can be harmful. It all depends on how, where, when, and why you apply defoliation.
People have a need to simplify things into being categorically good or bad but most good things in life actually fit into the as-needed category. Often times defoliation is not needed, but for some it could be.
I never understood why plants grew more vigorously after pruning.I've always noticed strong growth following some defoliation
Not claiming more yield.So my logic is that the remaining production lines have to speed up to process the undiminished inputs from the existing root system. Hence we observe 'stimulated' growth.
Overcompensation has been a major topic of study for decades, this might interest you https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6850278/I never understood why plants grew more vigorously after pruning.
Just 'regular' plants when I was reluctantly dragged out to do garden work as a kid.
It took me 25 year's to work out an explanation for myself, and that epiphany came from my fist weed grow.
Here's my theory:
Imagine the plant as a factory.
The roots are the raw materials arrivals input section.
The plant branches and leaves are the manufacturing production line.
The fruit and flowers are the output produced goods.
Now, for example, let's chop off one lower branch.
The factory now has one less production line running.
The factory still has the same amount of input material arriving.
So my logic is that the remaining production lines have to speed up to process the undiminished inputs from the existing root system. Hence we observe 'stimulated' growth.
Great find; I'm reading it now. I have noticed that when I let my herbs (basil, cilantro, sage, etc) grow, they seemed to stall out. When the wife needed some culinary herbs, I cut them and noticed that a week later they had grown back vigorously. I'm not sure if herbivores eating the fan leaves are a real "threat" to MJ, but I'm enjoying this experiment and anxiously awaiting the final results.
Hobbes, great test, I have found that yields do increase, maybe not enough, but have notice that bud formation if far superior..
The first Time I grew this strain I was using a black dog lamp and got 405 grams for all 4 plants.
This time, every thing the same except the light, I grew 569 grams, 164 grams more, An increase in harvest of 40%.
The BD had only 7 grows on it, it shouldn't have gone dim already.
Hat's off to the HGL Scorpion Diablo!
