Defoliating Test Grow

I like to fallow MR. Cervantes also, in his videos and Youtube.


But hey Mr. Greenjeans is doing a great job, proving the test.


Seems like, it does work.


Great Job Mr. GJ. Ill keep watching to see more, as they bud to the end.


:read2::read2:

 

I followed Mr. C when I was in high school.


I like to keep an open mind an absorb new things.


My thought on this before the side by side is even done.

Awesome for lower light levels. Do this in a high light room (over 4kw) and it ain't going to be as nice.


Just my two copper pieces.


Much respect to MrGj for the test. Always love these threads.


Cheers

 

I agree Usless that in a large grow taking leaves off may not be a good thing. My room is just under 7 foot high. Since I'm not growing trees and my plants are smaller this works great for me.


Here are the current pictures taken today. The plant plucked will end up with more growth. Notice the difference in the plants today.

 

yup in my lil closet grow the plants love it... looking awesome buddy

 

It's been 22 days since I first removed all the fan leaf's and started this test.


All strecthing is done and now the buds are forming. The plant that had the leaf's removed has more bud sites which get more light because of the missing fan leaf's. The plant is now putting more energy into the other bud sites.


Again I pluck one week before switching to 12/12 and then I continue to remove any new fan leaf's that appear that would cover up and bud from direct light for the first two weeks of flowering. By then the plant has stoped stretching and is now putting all its energy back into the bud sites.


Here they are just 14 days into flower.

 

opcorn-2::thumbsup:-Bud

 

Lookin good!

 

buddy


I dont get it...... your plants are so far along compared to mine. Today is day 13 of flower and I bearly have budsites. They are teeny tiny...lol..


MAD PROPS as always buddy:not-worthy::not-worthy::not-worthy::not-worthy:

 

OK nippie, While in Vegg I do not remove any fan leaves, untill one week before I flip the plants to 12/12. At that time I remove all the large fan leaves. I leave all the smaller ones on the plant. One week later I switch the lights to 12/12.


After I do that, over the next couple of weeks new fan leaves wiil start to appear, mostly at the top of the plant. I remove any new fan leaves that appear and cover any buds. After 2 weeks the fan leaves stop appearing and you are done removing any leaves. :bong-2:

 

29 days into flower. You will notice the plant on the left has a tone of bud sites on it compared to the plant on the right. This is because after removing the fan leaves, the branches get longer and this causes more bud sites that get more light. In the next few weeks the plants will start to put on weight and the buds will start to bulk up. I think you guys will be impressed in the difference of the two plants.

 

stunning boss


just truly beautiful plants

 

man could it be? You might just turn me into a damn leaf picker....

 

to me there are more bud sites on the plucked plant but the other one seems to be growing larger buds


t6

 

I agree the buds on the untouched plant look bigger but Im betting final weight will go to the defoliated plant. It appears the shear number of bud sites will end up producing more dried bud than the fewer larger ones. But we shall see...

 

Well its a good argument but I am sure green jeans has tested this probably multiple times on his own.


HOW DO FAN LEAVES FUNCTION


The large fan leaves have a definite function in the growth and development of cannabis. Large leaves serve as photosynthetic factories for the production of sugars and other necessary growth substances. Most cannabis plants begin to lose their larger leaves when they enter the flowering stage and this trend continues on until senescence (death of the plant).


Fan leaves account for the greatest area for the reception of photons on a plant, thus they account for the majority of photosynthesis which occurs within a plant. Cells in the plant's leaves, called chloroplasts, contain a green pigment called chlorophyll which interacts with sunlight to split the water in the plant into its basic components. Leaves only absorb about 15% of the solar energy that hits them, the other 85% passes through-- but they reflect all the green light, which means it looks darker below the leaf to a human than it does to the plant because our eyes are most sensitive to the green spectrum (Shipperke, 03.15.2002).


Photosynthesis occurs in all green parts of plants. The process has two stages, the light reactions and the Calvin cycle, that convert water and carbon dioxide into sugar and oxygen. These sugars are later used to power all the processes in the plant, including the synthesis of THC and other cannabinoids (Shipperke, 04.02.2002; Ca, 03.13.2002). Fan leaves possess the greatest number of stomata, which are small pores or valves on the underside of the leaf which water vapor and carbon dioxide diffuse during transpiration and photosynthesis (carbon fixation). Carbon dioxide first enters the leaf through the stomata and combines with the stored energy in the chloroplasts through a chemical reaction (the Calvin cycle) to produce a simple sugar. This sugar is unloaded into the tissues and transported through tubes in the leaf to supply the synthesized food to other plant parts such as growing or respiring tissues like young leaves, roots, and flowers of the plant. meristems (UK Tricky Knome, 03.14.2002).


Removal of fan leaves will not only slow growth, but it will also hinder the plants ability to rid itself of toxic gases, and also hinder the regulation of the plants temperature via stomata. Changes in the plants chemical metabolism caused by fan leave removal causes the plant to work overtime to rid ‘toxins’ with less leaves, as a result the pant may allocate more growth hormones into growing more leaves to make up for what has been lost(Equator, 03.15.2002). Removing large amounts of fan leaves may also interfere with the metabolic balance of the plant. Leaf removal may also cause sex reversal resulting from a metabolic imbalance.


There is a relationship regarding the amount of carbohydrates a leaf produces and CO2 intake relative to outside forces. When you have a situation whereby the leaf is no longer productive for the plant for whatever reason that may be - low light, old age, disease, insect attack etc, the plant will discard it. (Thunderbunny as citied, by Nietzsche, 03.13.2002.


Plants have two different kinds of vessels in their stems to move stuff around, xylem and phloem. Xylem runs from the roots up the stem carrying water and nutrients. Phloem runs both up and down to move sugars hormones, proteins, etc but mostly sugars. Each part of the plant can be either a sugar source or a sugar sink (Shipperke, 03.15.2002). Phloem moves from sources (areas of supply) to sinks (areas of metabolism or storage). Granted that the flowers can produce some photosynthate, but they are no where near as effective as fan leaves (resin glands significantly reduce light to the tissue they are found on). Flowers are sink tissues, leaves are source tissues. Sinks do not produce enough photosynthate, and are importers. Sources give photosynthate to sinks in closest proximity. Upper leaves bring sucrose to shoot apical meristem and young leaves while lower leaves bring goodies to roots (UK Tricky Knome, 03.17.2002). Remove the source and the sink will be affected (Diels Alder, 03.15.2002).


The leaves at the top of a plant tend to supply the top growing shoots. The leaves at the bottom of the plant tend to supply the roots. The middle leaves can go either way as the demand changes. During flowering and fruiting, only the very bottom leaves supply the roots and the rest of the leaves try to get as much energy as possible to the flowers of fruits. For this reason, the more leaves are unshaded and in good light, the more chance the plant has of creating extra storage of energy that will ultimately go into yield (Leaf, 03.13.2002). However Jeast (03.13.02) believes that the rich green leaves emerging from the bud are a sufficient energy source of solar energy for the plant's floral development. Therefore the old fan leaves are once again rendered useless and only drain energy from the developing part of the plant (Jeast, 03.13.02).

Judging by your post t6 I would guess that you don't believe in it. I never did either but I think that last pic he posted speaks for itself. It looks like more bud to me than the one he left alone. I guess the final test will be in the weight of each. I'm going to try it on a couple of my hempy and see what happens.

 

I remove bud sites and fan leaves
