Fan Leaves Removal During Flowering

[tomatoesarecooltoo]

schwazzing weed then running it through shredders and claiming that makes your weed top shelf? All done with way overcrowded clones. Yield would be better in standard sog. I urge everyone to do there own side by side comparison.

Yeah never got great vibes from the 3 a light guys, never tried their product so I cannot comment on the quality. But I have nothing but respect for Green Gene and Miami Mango who both kill it with this method, and both will admit that heavy defoliation is not the right choice for every garden.

Here’s a few of mine. Not the best. I removed a TON of leaves and feel it screwed me in the end. Not gonna do that next time. Maybe strategically removing the giant ones that are blocking the others. But only a few. Not 200 fan leaves at a time.

Fan leaves are an important part of the cycle of life of a marijuana plant.
the only time they should be stripped of fan leaves are at the end of week 7-9 or 10 depending onthe strains finishing cycle.
this plant is in week 7 and 5 days.
I will strip all the fan leaves starting tomorrow.
This plant should produce close to 1# when finished.

What strain? Looks delicious

Yeah, at that point you're just paying to light up the floor. The idea the fan leaves "block" bud sites is kinda suspect. That would mean the plant does not share its collected energy as a system and that each fan leaf is assigned a specific part of the plant... I don't really think that's how it goes

Well I asked on here and couldn’t get an answer as to what’s more important to get light. Bud sites or fan leaves

also. Regarding 1lb per plant. We need wayyyyyy more info lol. Single plant in a 50gal hydro setup vegged for 4 months under a 1000hps light I’m going to assume lol.

Part of my defoliation was aphid control too. Learned lots that’s for sure.

The answer to that is all of the above.
The energy you want going to the buds comes from all the leaves.
The more leaves the more energy to the buds.
(Photosynthesis) :)

Some of y'all don't watch Dr Bruce Bugbee and it shows

Well this is right now... plants look happy and not stressed after the heavy defo i did.

Well gee. Where were you with your grade 2 pictures when I posted this very valid question that no one seemed to know the answer to.

Am I ok to remove these leaves?

What’s a priority here as far as light goes for a plant that’s in 4/8 weeks of veg... fan leaf surface area or bud sites? the LST plants have seem trimming. And defoliation. And are smaller the other two have only been topped and very little defoliation... they’re huge. Maybe I’m onto...

My grade 2 picture points have a purpose.
Plants need leaves for photosynthesis, the more the better for bloom growth and the health of the plant.

Photosynthesis | Definition, Formula, Process, Diagram, Reactants, Products, & Facts | Britannica

Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

25 gallon pot in soil, clones were takin September 3, veged under 315w CMHs
Flowering under 1000W gavita DE, CO2 at 1500ppm in a sealed room 10x14 with 10 foot ceilings. 4 ton A/C temps at 72-76F in flower weeks 1-6 temps dropped to 66-68F to finish week 7-8. Gavitas upped to 1150W last 2 weeks of flower.

Is that 1000 wt per plant?

Ever notice how your stickiest, best tasting buds are always under the huge shade leaves?

my yields were also shit.

can you not think of any reasons why?

just by simply looking back through your posts. you've over fertilized, put your lights too low, had to upgrade your lights, had light burn, been battling aphids for most of the grow, topped numerous times, done heavy defoliation and lst multiple times during veg, had ph issues, temperature issues....

l'd suggest your low yeild was because of a multitude problems and not necessarily relevant to what the OP is asking.

 

[1diesel1]

Is that 1000 wt per plant?

4-1000w gavita DE in a 10x14 foot print evenly spaced for maximum light exposure.
with these dimensions each light overlaps the next approximately1-1.5 feet with the wider hoods.

Over fertilized how?? First grow I used double the amount (recirculating) and had no problems. Tinyyyy bit of tip burn but that’s about it. Second grow I used half the nutrients (drain to waste program) so how exactly was I over fertilizing when I fed them about 700ppm once per week. They were starved if anything.

lights too low? When? Where? Where was the light bleaching and damage showing that??? Where’s the light burn? I had them too high at one point (60cm) and then lowered the (30-40cm). I seriously think you got me confused with someone else

it all worked fine for my first grow. The light that apparently needed upgrading, the over fertilized plants. Etc. My first grow went great with all that stuff. The second grow was absolute shit and I feel it’s because of the major major defoliation that I did. Since when is basic LST responsible for hurting yields when I vegged for 2 months

where were my ph issues? I was at 5.75 to 6 the entire grow? So was I over feeding or under feeding due to my ph issues???

The only major, possibly negative thing I did different between grow 1 (3.5 oz per plant) and grow 2 (2 oz per plant) was major defoliation. Absolutely relevant to what the op is asking

I feel like defoliation and stripping the plant to nothing except a bud site is what caused my shit yields because I didn’t really overly struggle or fail at any other areas. I made a mistake or two and had a problem or two yeah. But the biggest, most significant one, I feel, was defoliation about 200 leaves at once, several times throughout the cycle with no recovery time. I tried asking and getting an answer here but not a single soul knew that very basic and apparently obvious knowledge. Learned that one myself the hard way over a period of 6 months. Awesome.

Gotta love forums and sharing knowledge so mistakes like that don’t happen and basic questions like that can be answered and not just ignored. Awesome communication we got here
