Fan Leafs. Blockers of Light Or Energy Producers???

you cant grow plants that big under a 600w shits for brainses

what you talkin' bout pimpin?

We did get played with the 600 watt lamps, I use mine
for vegging. Fux got the nerve to charge more money for them also.

Inverse sq rule, waaaaaaait for it

willis, this is what i be talking about. plants can only be like a foot tall under a 600. people dont have good lights and they dont lst so they cut their leaves its bafflement

Do you guys even own a light meter, because obviously you have no idea what your talking about. The fan leaves I was talking about are near the top of the canopy anyway, where there's 7000+ foot candles. The shaded leaf is not even centimeter below, and I can see an obvious shaded leaf shaped yellowed area.

Every grower does what he/she does....There ain't just one way....
And lights passes thru leaves...I don't know to what extent, but you can find that anywhere with a quick search.
I googled...."Does light pass thru cannabis leaves".
The first thing that popped up is Ed Rosenthal....I think I have 3 of his books. Atleast 2.

<-Is this not fate for tonight?! I've have SUCH A GOOD DAMN DAY and here we go....
A link from an OG.

And I can't cosign for plants needing to be a foot tall under a 600w lamp..Not nearly.Every grower creates their own art.

Peep that link tho...

I didn't come across is before I said anything that I have prior to all this..
But it sure sounds familar

this guy needs to take nitrogen 101 again

my six hundred shines down through about a foot of vegetation, no more. these are basically small plants. bigger than that, yeah shaded leaves, get a bigger light or grow a smaller plant that fits ur light

The extent of how far the light travels though leafs is my area of study now, I know different colors travel farther than others.

also the amount nitrogen available effects the leaves transmittance ability.

Transmittance zzzzz zzzzzz mmmmm traaaaansmittance ( that's me dreaming)

Defoliation involves removing some of those larger too, so that you can get some light to those budsites.
And OG says 85% passes thru the leaves...So removing the scraps at the bottom makes since..
Unless you have supplemental lighting there...Then we're talking a diff. ball game..

Just my opinion...Ain't claiming fact
Maybe I come across something tomorrow that sway my mind. But until then......

Respect your elders people... UB might not be the most patient person around, however, he is giving his experiences of growing for FREE... Not trying to make you pay for it like any "normal" "nice" hypocrite person.... There is a price to pray and is to listen after a million of oboe including myself ask and state the same stupid shit over and over claiming that we are re creating the wheel again.. Like the old say goes... The young can do but doesn't know how... While the old know how but can't do...

No, patience is not my virtue, I'll admit, especially when folks do not have a grasp on the difference between topping the tip out and topping cannabis to transition it from one to 4 main colas.

Noobs.....there is a difference. LEARN it.

So after 20 years of growing (by your admission) and the fact that your dad has been growing since the 70's, which makes you a little munchkin, you're just now discovering what?

Posers come and go around these parts.

For me, in due time. Unless your "Uncle Bens topping" thread gets deleted, I'll be utilizing the methods that you employ.

You are wrong again, he is correct. R and FR light transmit through leaf tissue.

This is from green mans page :

200 - 280 nm UVC ultraviolet range which is extremely harmful to plants because it is highly toxic.


280 - 315 nm Includes harmful UVB ultraviolet light which causes plants colors to fade.


315 - 380 nm Range of UVA ultraviolet light which is neither harmful nor beneficial to plant growth.


380 - 400 nm Start of visible light spectrum. Process of chlorophyll absorption begins. UV protected plastics ideally block out any light below this range.


400 - 520 nm This range includes violet, blue, and green bands. Peak absorption by chlorophyll occurs, and a strong influence on photosynthesis. (promotes vegetative growth)


520 - 610 nm This range includes the green, yellow, and orange bands and has less absorption by pigments.


610 - 720 nm This is the red band. Large amount of absorption by chlorophyll occurs, and most significant influence on photosynthesis. (promotes flowering and budding)


720 - 1000 nm There is little absorption by chlorophyll here. Flowering and germination is influenced. At the high end of the band is infrared, which is heat.

It's true. You know who else did that? Jorge Cervantes, aka George Van Patton.

I was born in 1973, so perhaps to an old man I am still a munchkin, but my two kids think I'm god.

I grew my plant first ganja plant 20 years ago and had several outdoor harvests between then and now. I didn't say I had twenty years of growing ganja now did I? I have taken several college level horticulture classes in that time, but have not grown weed every year. I just started growing indoor in the past couple years, so yes I'm just trying leaf removal now. Doing it for outdoor grows would be somewhat pointless IMO.
