Who Is Plucking Fan Leaves That Block Bud Sites

[SoLowDolo]

During veg, I have been plucking leaves to help keep my canopy even, and to let more light penetrate. I will pluck the fan leaves off the growth tips that I want to grow a little slower, and I leave the fan leaves on the growth tips that need a little help to grow faster. It's cool to see the relationship between them and it's kinda become part of my training now, along with topping and LST.

That's what I believe, some of the elements they need to grow are only picked up in veg, and like you, I think it's stored in the old fan leaves, and when it needs it, it just sucks in a leaf. A good example is when a plant finishes flowering, it sucks in all the fan leaves, some of which were produced in veg.

The leaves go from feeding when young (source) to storing and redistributing nutrients later (sink).

And I wanted to say since this argument is not advanced as usually labeled but something we read as new growers and wonder about that the more leaves left on the plant through the whole cycle the more chances mistakes will not hurt yield. The leaves will feed the plant when we screw it up. That’s why they store nutrients. To feed their flowers if no nutrients are available.

We all have valid points. aside from nutrient sinks for use later, primarily the leaves are the plants solar panels to drive PS and feed the plant. Hence if we reduce the number of active solar panels then don't we indeed decrease the photosynthetic process which in turn limits the plant from building and drawing from the nutrient sink????

Long story short, if we take away the panels by pruning etc. then the plant isn't producing to its full potential. Even with the available nutes stored in leaf and tissue with out full photosynthesis available the plant isn't creating fresh food and all the stored nutes are for naught, correct???

When I was outdoors years ago it was the plants that didn't get defoliated and had some partial shade that grew the fatter more colorful buds/colas as opposed to the plants in full sun all day and had been defiled. food for thought eh?

 

[RippedTorn]

Every part thats green is a solar panel, chloroplasts don't discriminate. How else would a cactus grow with no leaves.

With that said training comes before plucking. No one likes a crowded elevator. Some rooms are just beginning for pm.

That's why I didn't really defoliate on my first grow especially during flower. I treat the leaves as a buffer between me and the buds. The leaves would tell me what was wrong and what I fucked up, and I would try to fix it before it got a chance to affect my buds. And it would feed them if I forgot. It seemed as though things would effect the leaves first before the buds but I never really knew if it was true...

Absolutely the leaves will go before the buds. The plants pants only mission in life is to catch pollen with its flowers.

Even if the damage climbes to the bud leaves and they yellow and maybe even some tip burn you can still usually salvage some ok flowers.

Seems they get frostier from the stress sometimes. But unfortunately more frost does not equal more potency.

Agree, some of the most frostless buds typical:D with sativas as compared to indicas has been the weed that spun me out since the early days of my toking. A good indica will always typically out frost a sativa but some of the best mind f*** weed I have smoked was minimal frost and was indeed sativas. So frost factor isn't proportional to potency. :smoking::fire::fire::fire::fire: by the time we were getting thai styk in the states there wasn't a very frosty array of trikes but that shyt would send you on a great ride.

I just let em grow, she always takes care of her self if I’m doing my job rite!

 

[chillywilly]

Wow...really nice...lot of work he he...

 

[chillywilly]

Had sativa seed banks white lady(Nirvana) almost no leaf to trim ...2019 going to do a seed spray...truly exotic ... ...Roses...mmmmmm.

True and false. Unless the leaf is getting adequate lighting, being shaded by other parts of the plant for instance, it will take energy away from the other leaves that have to support it.

Cannabis requires around 200PAR of light to keep growing taller, so I would assume that all leaves on a plant that get less light then this, will be sucking the energy out from the top leaves.

This is not correct. For one the leaves are mostly transparent to light. It passes through them and the plant takes what it needs as it passes through.

Also if upper leaves need nutrients and they are not being taken up through the roots adequately the plant will move what it needs from the lower leaves to newer growth or flowers.

The only “energy” is the light source. There is no energy robbed from other leaves. They are either a source of nutrients or a place to store them for later. (Source or sink)

 

[Homesteader]

Blue light has more energy because it is short wave and passes through leaves easier than red light does which is long wave. This is also the reason the oceans appear blue. Red light penetrates less than blue light does.

In response to partial plant shading, the lack of phytochrome A does not directly induce leaf senescence but alters the fine-tuning of chlorophyll biosynthesis

I hope this reasoning will be enough to convince you otherwise..

"photosynthesis, to create energy from carbon dioxide and sunlight. This energy, in the form of glucose, is used by the plant to grow and fuel the necessary reproductive activities of the plant".

If a leaf does not get sufficient amount of PAR light and/or CO2, it will not be able to photosynthesize. Meaning that it can't produce enough energy on its own to sustain itself. However glucose is a mobile energy source, and other plant leaves can transport glucose to those leaves that are unable to create it by themselves. By doing so, this energy is not used on developing roots or bud growth.

Leaves can take away energy (glucose) from other parts of the plant if they are not able to create their own energy (glucose).

These points are assuming the source Lang is in shade from something else. Not it’s own leaves.

It is not a problem in a properly lit growroom or outside.

You are arguing with what is known as confirmation bias.

Huge buds grow in the middle of my leafy canopy even when hidden under big fan leaves completely.

It's interesting to read these and try to guess what kind of grow the author has. I picture most of the non pluckers with a more open space and or well trained/manifolded plants and or ability to adjust colas around through flower. Outdoors is easy, the earth rotates your light source all day everyday. Heavy pluckers I picture as scroggers, which many of them stated, and look at plucking as mandatory. I'm in the scrogger camp personally, @1diesel1 was a surprising one to me though. I'm not challenging anybody, not really a right or wrong on this one, just interesting.
