Giant fan leaves in way of budsites...

I have quite a few mostly indica plants outdoors budding that range from 4-5 feet and their fan leaves are huge and block out direct sun to the budsites, I usually just tuck my fan leaves, but in this situation its not possible, should I trim them or let the be?

Thanks

leave them some believe(me included) That the leave are the solar panels for your plants they convert the light into sugars and energy for the plant
I have also read somewhere that the leaves are 25% opaque so some light passes through them, but i dont know how true that is

when you think about it, only a very small portion of the plants total budsites are being "blocked" by the fan leaves.

sunlight does make it through fan leaves.
Yep.... sunlight doesn't go through black plastic but my plant grew a big fat bud underneath it anyway. :D Your bud will grow large and then the fan leaf will fall off and the bud will still mature in the sun properly. :D

I have a friend,that supercrops those big fans,and it works good,without trimming.

I've never understood why anyone would think that light getting to buds is important. Why would a bud need any light to get to it? And cutting off the leaves to allow it?

Buds don't collect the light energy, the leaves do that.

I dunno, Ive heard this before too but my feeling is that photosynthisis does take place in the buds as well. its green, and contains chloroplasts which facilitates energy conversion from sunlight. otherwise, the flower would be a different color, like petals on a rose for instance.

well yes thats true to a point, but the stem is also green, and therefore contains chlorophyl, but that doesnt mean yield is enhanced by stripping the plant back to the stem. The leaves arent only the major power factory for the plant, but also provide a place for essential gass exchanges to happen. These are essential for photosynthesis to occur. The buds are essentially a housing for wouldbe seeds, and while they are basically leaf material, they arent designed to be super leaves in hiding, waiting to be exposed for nature switch its turbo boosters on. If the plant didn't need leaves, then they wouldnt spend the resources on building them.

buds do actually grow bigger with direct sunlight. a couple of fan leaves shading a bud will slow it a hell of alot.
remove some if you think that bud will actually grow alot better and its nearer the top of the plant.

no it won't. maybe inside a grow room. not outside under the sun. the sun's rays go right through that fan leaf. as someone has already said that fan leaf is acting as a solar panel.

With outdoor plants you can without any problem remove the big fanleaves once a are about halfway flowering or in the final weeks.

it will actually cause the buds to become a lot bigger cuz there is much more light.

Outdoor plants usually have literally too many leaves

In most cases your right, but bigger buds i have not noticed, another thing when outdoors is the fact that humidity plays a big part and the more air circulation the better....hence compact plants and bud have a fair chance for mold attacks :2cents:

anyone ever do a side by side of the same clones and removed the fan leafs off 1 and left the other alone?

from a different thread:

better light penetration and distribution. let's go with the solar panel analogy... <br />
<br />
if you had a whole bunch of solar panels overlapping one another randomly and competing for space, do you think they would be as efficient as a single solar panel occupying the same space? or an array of panels that covered the space perfectly? my feeling (I said <i>feeling</i>, so if you're a botanist and think I am wrong, your science probably trumps my feeling) is that its the same with the ganja plants. <br />
<br />
I prune fans so that there is as little competition for light as possible, but also that as much surface area as possible is covered with leaf, but only on one plane... I usually take off the oldest fans first, which usually un-shades a cluster of newer, more vibrant (and maybe more efficient?) leaves beneath it... if any of those new leaves are competing for space or restricting airflow (I refer to this as a clusterfuck) i take one or two of them out until I feel that what I have left behind is the most efficient.<br />
<br />
Indicas seem to need a lot more of this than the haze x's I am growing. I have heard people complaining that they can't get some strains to get huge. In my garden, multiple people have said this about the Grape Ape... <br />
<br />
The guy I got the cut from was over last week.... I mentioned this to him and he was like "Mine is 10 feet tall..." Obviously, my next words are something like "How the fuck...?"He tells me that almost all strains have a training/pruning technique that will turn them into monsters. For the grape Ape, she wants to have all the long-stemmed droopy fan leaves removed... DURING VEG!!! This was unthinkable to me, but you can't argue with his ten foot monsters. You could, but they would make you their bitch.
<br />
<br />

If light penetration were unlimited in its power, it would simply burn through the leaves like a laser beam. If, as one poster stated, half the light gets thru a leaf, how many leaves before this half life renders the light useless?

What about popcorn? The more light you get to the bottom and inside of your plant, the more substantial the lower buds.

I think that the reason your fans start to die at this point is because your plants have stopped using them as solar panels because they are old and inefficient... they just suck the nutrition out of em and use the healthier, more efficient parts of the plant for photosynthesis. While I have not done an plant vs plant comparison, I did successfully eliminate most of my popcorn on my last *and first* harvest by letting more light in.

The whole idea of leaving your ganja plants alone to do things on their own is just laughable. No offense to whoever said that, but the art of growing good ganja is exactly that.... our selecting, training, feeding, pruning, supporting and loving is everything to these plants.

I believe that if I just left my plants to do their own thing every time I thought I might be able to help in some way, I would not have the thriving plants that I have today.

Also, trimming fans increases airflow which lowers the odds of mold. Mold can eat more of your crop in one overnight than a 10% inbcrease in photosynthetic efficiency would increase it. So even if I am totally wrong about the light, its not a bad idea to keep your plants trimmed just enough to encourage better airflow.
