Is it risky to remove fan leaves 5 weeks into flower?

Hello All,
Can the plants get stressed if I remove the fan leaves that cover bud zones that are developing? Is this a risky procedure? I have been bending them back out of the way so they do not block light shining on buds.

Is it better to bend fan leaves even if they fall off later because the fan leaves aren't getting light. Would be better then just breaking them off during flower? Or have I lost my window of opportunity to defoliate because veg stage has past?

Opinions Appreciated.

Beyond what has been stated above, the plant can also draw stored nutrients from leaves that may not be getting much light if it isn't getting enough of what it needs. There just isn't a good reason to cut leaves off unless they are already completely dead.

Sweet baby Jesus so much misinformation with no backing, I shall instead point you towards proof. http://www.growweedeasy.com/marijuana-defoliation-tutorial

Rule of thumb and I have done it personally, remove no more than 3-5 blocking leaves a day after week 3-4. I go as far as removing weak @ss lower branches aka popcorns and see no I'll effects the plants just keep on growing.

MOST IMPORTANTLY your plants must be healthy to do this. No nutebruned to hell, sick or starving.

Bull shit.

Without proper technique this will cause more harm than good.


Defoilation is only helpful in certain situations and reccomending to a new grower is not advised.

I will say if the op tries it, it would be smart to trim one and leave one. Look and see the difference.

About the only time I cut a leaf is in thick canopies and mold is a risk or the leaf is dead already.

Unless it is a a scrog or other training with very thick canopy there is no need.


A pic would really help to see if it even needs it.

That's not proof either. Its one mans opinion.

He did show pics but with no control plant. No way to tell if it actually improved yield.

I agree with nanogadget. The cannabis grow world is full of silly myths.

Cannabis is a plant like any other. Keep it happy and healthy and yield will follow.

Calm down there space cadet, both of you showed zero proof of your words, have either of you done it? There are literally dozens of pages of people lol popping and defoililating and gaining success, there are NO pages showing the opposite.

I have done it, I know people that have done it, but none of them have failed. Please show me proof I love to learn not spout useless information.

acording to the research i have done. There are major grow ops that swear by defoalation but even they say results vary by strain. I agree with white though. Not recomended for beginners. If you have to ask then dont do it. I have been growing the same strane for 2 years. Thc bomb and like bob i only remove from an over dence canopy to improve air flow. I strip everything under the top 2 feet. I dont have to wory abought fan leaves blocking tops necause they are trained to have 10 tops each all within an inch of height

depending on your expectation of diminished yields, open plant wounds, less photosynthesis, less vigor etc...no its not risky just plain dumb

im assuming you know this from extensive testing and research and it isnt just an "educated guess" i have seen deer totaly destroy a plant and that thing come back ant dwarf its neighbors. every comerical grow i have ever seen the plants are loplypoped. again not a fan of deleafing colas myself, but im also not a fan guess work being presented as fact

Yes I've done it.

Its basic botany dude.

Show me a controlled grow with several sets of clones.

of course. if there were tricks for growing marijuana they wouldnt be called tricks they'd just be the way we do it.
op is questioning "removing the fan leaves half way through flower, not in veg. We all know that we can cut a vegging plant right down to the dirt and watch it grow right back up. but not so in flower aye.

be design the plant is programmed to succeed in bringing an optimal amount photosynthesis to the plant so it can be the healthiest it can be producing the best flowers it can in order to support the best seeds that it can. Removing leaves in flower negates this photosynthesis as there is no time to regrow new leaves for a recovery. Less energy is less energy.

almost surprised marijuana outdoors doesnt shed all its fan leaves before flower production...tehe

Tomatoes dont shed there suckers but pruning them has shown to increase yeald. Just sayen lol. Again just passen time playen devils advocate.

We are not talking about cutting suckers off.

I break the suckers off my corn.

I might cut a few smaller lower limbs here and there. Only on certain strains and if it looks like it needs it.

The op is talking about cutting fan leaves off. The very thing that drives the plant.

Its not rocket science. Its basic horticulture and botany.
