Defoliation: Hi-Yield Technique?

aside from the fact your pictures suck looks ok.

Try side shots, closer even. gives far better perspective than above looking down at a pin.

Ok so my plants are getting to be the 6-8" tall and ready for their first defoilation.

I can see the normal fan leaves that shoot down to the main stem & know I am supposed to remove those, but the fan leaves that meet the stem & have a bud site growing out of it I want to leave alone correct? Or so I want to remove the fan leave but leave the bud site?

Does anyone have any good pics or was a video ever produced? I'm new to growing cannabis in general, so there's a bit of a learning curve.

I should also "Top" them now correct?

Also for someone who has never did any type of LST or anything, what would you guys suggest to do? Bend the main stem? Super crop the main stem?

Thanks.

js topping at the second true node will give you 4 mainstems

been doing this for a year now.

Apparently once the plants are done stretching, the fan leaves for the most part have done their job,

I dont remove the leaves from the buds or near the buds, basically any fan leaves that dont show any trichomes...

Ill update this thread with pics once we do this in the next week on our current run. So far, I just think it allows more light to penetrate the plant, controversial topic, but Ive seen no health related or yield comprimising results other than good things...

This is Day 29 of my grow & I just switched them to veg on Monday.

Well I gave a solid attempt at Defoilation & Topping/FIMing:

I only took the fan leaves off, even though I took them close to the bud sites. I hope all is well.

js did you mean switched to flower?

lookin good and healthy

No we just switched to veg. We started from seeds & kind of had a slow start.

I cut off all fan leaves, including the ones that were directly by bud sites - I made sure to be careful around the bud sites, but was it ok to cut these off too?

I obviously left some fan leaves, the smaller, more undeveloped ones.
 
Exactly, you want to allow that leaf to trich-up for processing for it's keef content...and to support the buds growth.

and concur on the LIFE... LOOKS REAL GOOD MAN!

Ahh shit, after taking these leaves off I find this post. Is it really bad I removed fan leaves from the bud sites? I just switched to veg earlier this week, so I'm hoping they will bounce back and be ok...

Can't wait to see... did my last removals about 4 weeks into flower. This was done mainly to give more light to bus sites directly covered by a higher fan leaf. I like the idea of removing everything but the sugar leaf.

Hello!
i defoliate all the time in flower, when stop stretch and must say realy works.
From last round chronic 27 plants i get 1g/pw. when seeds germ i veged 1 week and flip 12/12.

Now i have critical+ and i was defoliate and after one week youst cant belive how looks the lower buds to.......but infortunly i get hermies all orund! from 47 plants are 4 not hermies!
so how possible is i get hermie beacuse defoliate?

Things have been going great, the plants couldn't look any healthier. They have finally bounced back from defoilation & topping.

My mate is kind of mad I topped so early as he said they haven't grown much taller since because of it. They have realistically probably grown about 6" in the last two weeks, which is slow. They should start getting taller soon right?

I assume defoliating & topping stunts their growth a bit right? But it should dramatically increase yields, so I say it's worth it. I want to top them again so I have 4 tops total, when would you suggest this?

Here are some new pics, as you can see they have really grown in since defoilation.

When do you think they are ready for a 2nd round of defoilation?

look nice! you can defoliate again!
I think the best time for cut is after two or three weeks (in my couse, after 2weeks), when stop streching! I think this is the best time so the bud sites/branch can establish!
But...if you defoliate first time in flower and have some more sensitive strain and you didnt prepare for defoliation in veg time you could get some hermies! like i did:)

Hey Johnny your plants look real good and i like your vert style!
but has it really been since end of dec that they only this size now?

I had some slow plants recently but that was due to the temps getting to cold at night along with my water (hydro wilmas) but thats since been sorted and they only just show good now,

I been growing some uk cheese, out of 20 seeds i got about 4 very nice keepers( better get some cutting as i already got some but dont know which plants which!)

, i am 3 weeks into flower and am going to trim up a couple of crap looking plants and see how it affects them,
Damage control for next round!
What size light you using there and when are you going to switch to 12/12?
cheers an good luck
 
Hay killa420 I looked at your grow and seems to me you should get those fan leaves off.... Yep all of em.. Looked like you took clones from the bottoms but I didnt see any defoil happenings? Those big stem fan leaves with no bud sites should be removed, you said you removed (defoiled) the lower part of the plant to let light through but I dont think your light is positioned under your plants.... Mabey it is... But usually they are installed over top.... Not trying to be rude buddy but you might want to take a look back at the beginning of the thread on the removal... Just have faith and pull of the fans at the top and bottom of the plant... Your in veg they will come back, train your plants a bit more horizontal... good luck and no worries...one love
 
Yo bro thanks for the council. I am switching to flower today so I was recommended to do the bottom
Third and wait three days. Naw dude ur not rude that's y I posted the pic to get advice. Yea I was a bit weary of pulling them off as u know this is a well debated subject. Should I still pluck my upper leaves? How about the smaller ones as well. If so then I think I will do one N not the other. Tunis again bro

hmm, i tried defoliation, did it in veg (in flowering i just tucked the few fanleaves out of the way)

i like the growth pattern this creates, but the plant hermied, i see others have the same problem.

i dont find the growth pattern that appealing, i´ll probably just lst in the future lol :)

The bottom third that you pulled is a process of training to get bigger colas at the top of the bud for grows where as the light doesn't reach to the bottom of the plant with end result of fluff or pop corn imo... With defol you want to keep those buddies on the plant while removing only the shade leaves which in turn creates a compact branching skinny looking plant that by end of flower is a full bud on every branch and quality nugs on the bottom and top. I pluck all fan leaves knowing in two weeks I'm going to pluck again and then again until its really too sticky.. Large fans always the first to be removed...then pluck the medium sized ones and if I seea tiny leaf that is going to be a fan some day consider it gone as long as I don't hurt thr bud sites or waste any if my sugar leaf.. I think most people prepare the plants with a longer veg time to ensure the plants stay healthy and don't hermie from stress, and others see no stress from plucking in flower only. The best way for your particular set up is really developed by you... Defoil works great for me with a small legal plant count with a small flower area. But I've seen awesome tree grows, super scrog grows and small cab grows like pipedreams 150w.. My recommendation is follow k33fertrees says to defoil then make it work for your set up... One love this plant was 8wk hindu kush plucked all veg and flower until about wk4-5..

In veg you say you plucked and in flower you tucked, but if you plucked in veg it was sort of a waste not to do it in flower too imo, but I was wondering did you like the growth pattern it creates or did you find it unappealing? Lst+defoil is a great option....if you liked the growth pattern...but if you don't find it appealing mabey not...:comfort:

no idea of its name :) and yes, its possible that its genetic, not the technique and its also possible some strains might be more sensitive to the technique.


maybe ill try again later, this was a very bushy strain, i dont have anything that really needs this now.

oh and it did not hermy to shit, maybe 20% hermy. maybe less, possible 10% (its still flowering, the only one im flowering at the moment and like i said, it wasnt that much hermying.)

but usually, i have run very hermy strains (100% hermy for others)

and gotten them down to 5% hermies (about 1 seed per bud or less, down from mostly seeds and little bud (the guy i got the plant from))
