Cutting Fan Leaves? A Mythbuster style experiment...

fan leaves collect light and feed your plant whether the buds are blocked out of direct light or not.

Thats a fact.
So you're saying that if I cover a branch with a black bag, the rest of the plant will feed it and it will grow a nice fat bud regardless???
I don't think so.

lol Wow what a can of worms you have opened here. The fact is I doubt that any of us are botanists and any testing we do is not done using scientific testing methods. Seems to me like a preference issue. Mel Frank has done alot of these sort of tests and has published alot of his results.

Sorry folks - but due to peoples complete inability to read - particularly the first lines of this thread, I'm unsubscribing my own thread. I've grown tired of repeating myself.
Thanks for the support for those who've offered it.
I will continue the experiment - but don't expect any further updates from me. I'll post the results when it's all done for those who are interested.
I don't need this...

Just read through this entire thread only to find out you've been subdued by the critics.VERY LAME Pullin' weeds!!! Understand people are always going to bicker and fuss, and it's not your job to squash or validate these malcontents' arguments. Your job was to post pictures and publish your data/results/findings. Stopping this experiment or hoarding the data is pitiful and just reflects your weak character. If you can't stand criticism, you shouldn't be posting anything on any forum because someone is always going to disagree with you.

For what its worth: I thought you had a good founded hypothesis though your methods weren't all that great (as many pointed out) considering you would not be able to isolate the energy (glucose) made by trimmed or non-trimmed foliage to each system. Flawed as it was, valuable insight still could have been gained.

this is bullshit people!!! i had a sincere interest in this thread, no matter how worthwhile it was. and y'all done run him off his thread :fire: i'm pissed!!!

Damn. I wanted to see the outcome of this too. I did this same experiment in my garden this run, but the two girls I had tested it one (one trimmed, one untrimmed) - one went hermie on me. The strain is fairly unstable come to find out, just bagseed, but I have a bunch of those seeds. Hope he comes back, I'm sub'd.

Troll.
You're not from Santa Cruz. There are plenty of bridges in LB for you to stay hidden under. Stay the fuck out of SC.

Yes that's a fact. But that fact doesn't mean that removing fan leafs one might still get a equal or greater yield because of other factors under the right circumstances.

People keep talking about side by side, I only did it once, removed most the fans from one clone and none of the other and got the same yield from both. Everybody told me before I did it that I would lose yield, a fact! but I didn't. Keep an open mind that all our facts might be true but we might not know how they fit together.

He's right, the whole plant will suffer from the over pruning not just one side. The plant will struggle to meet demands to respire with less surface area resulting in the whole plant being affected. Photosynthesis will also be impaired, meaning less energy, for the plant as a whole to do its job,

Thats basic Botony grounded in science......., uh experiment over I think.

hmm.. this is an interesting statement. Any people know if this is true?

I mean, I would think it would be truth as the plants get nutes from the roots, there shouldn't be any difference between each side...


I mean, lets take a simple example like topping. Lets say a guy tops the right side of the plant but leaves the other side alone. What eventually happens? well, the left side will definitely grow taller than the right right. if I were to say, if you cut the fan leaves and the plant uses the leaves to collect energy from the sun, you would be hindering performance.


lets take it to the extreme. you have two plants right next to each other. you each plant has 100 leaves. you take off 30 leaves so that the plant can produce more bud while on the other plant, you don't do anything to it and just let it grow. Logic tells me that the plant with the 100 leaves would surely produce more bud because its collecting 30% more sunlight than the other plant.


one more... From experience, I know that the plant with more leaves on it is usually the most healthy. So lets give another example... You take a clone and veg it for 14 days. If any of the leaves from the plant doesn't get enough light to justify being on the plant, the plant will kill it. I'm sure you guys have seen yellowed leaves that were getting no sunlight just drop off of the plant. so.. it would make sense that if the plant wasn't getting any benefit from a leaf, it would drop it off.


ok one more.... ( last one i promise) If a huge fan leave is 12 inches by 12 inches and the bud under the leaf only had 5 inches by 5 inches of total leave material, which would is producing more energy. I would say the 12 by 12 huge fan leaf.


conclusion: cutting fan leaves on the same plant would affect the plant as a whole. why? well, the whole plant is connected BY the root system. by cutting off fan leaves, you are essentially killing off the energy that the plant would received if you didn't cut the fan leaf... If that makes sense. but... even if you did cut the fan leaf, it isn't hard to figure out which side of the plant would grow more leaves.. i'd just tuck the leaf under to give the bud some light or some times I just say screw it and do a staggered harvest ( harvesting the small buds a week or 2 later) which is cool with me.


more leaves = more energy for the plant to receive ( in an already low light environment aka flowering) = more... well you get the idea.


it makes logical sense to me but my logic may be flawed somehow.


I'm not trying to "feed the troll" or be a troll myself but it is a valid question.

I agree - it's not "real science". I don't have a controlled lab, I'm not recording anything - I never claimed it to be real science. First sentance of this thread - "I'm doing this for my own interest". If you don't like it - run your own experiment. I'll be happy to read your results.

I'm not testing "trimming stresses the plant, decreases yield" - I'm really first testing the more basic idea "does one side affect the other". Most people say it does - I'm not convinced. Water and nutes affect the whole plant, but those are different plant system than photosynthisis - which is more localized. The flow of water and nutes travels in one direction - from roots through the stems and out the leaves - this leaves little room for any lateral transfer of energy. One side shouldn't give a damn what the other side gets
Wrong thought process....

When you cut the plant, auxin is realeased. It isn't released to one side, it is released throughout the plant.

I'm at a total loss as to what data you think you will take from this. If you truly wanted an experiment to dispell or support a theory, you need control plants, or a control plant, preferably 2 clones. You trim one, and not the other and then compare the two.

Your method will not support either side, as it is useless....

well.. if you removed a negligible amount of leaves.. the yield difference would be... negligible correct? try removing a substantial amount and see what happens.. I believe we both know the conclusion of that...

you will see the difference if you were vegging the plant and had taken off 50% or more ( probably morel ike 70-80% because that would be most of the leaves) leaves on one plant and none on the other. surely, you would say that the plant with more leaves would yield more correct?

idk.. it just makes logical sense to me.

Findme...... Let's take a look at that 12 by 12 fan leaf that produces more energy, as you say. Which one is taking up more of the plant's resources? the 5" leaf or the 12" one? How can you say that the energy and water used to support the 12 inch leaf is less in proportion to the 5" leaf and it's contribution to the plant?

I remove all large fan leaves at the bottom of the plant when my canopy is established. They aren't getting light and the water, nutrients, and energy used by the plant to keep those leaves alive is wasted.
