LED and BUD QUALITY

Has anyone determined if full spectrum is best?? MH is very blue and HPS is very red. Always thought that was best way to grow instead of using same light for everything. Surprised LED makers are not making separate lights for veg and flower.
From what I have seen in LED's full spectrum is white, a combination of all colors, but visually white to the eye.
My Spectrum King were supposed to be full Spectrum so were my Mars Cobs Everything I grew under them looked defficient and yellowed prematurely, and produced slighted buds with higher leaf to flower ratio, just my experience.
And yes they do make led for veg and flower usually now on the same fixture with a flip of the switch. I tried all grow just blue and white Led looking very Blue, my plants were just Ok.
Under the blue red heavy combo galaxy's, great every step of the way. so not looking back.

My Purple line grown under red heavy Galaxyhydro now Roleadro, proof is in the nugs!
And no they don't lack for anything in quality.
P.S. These ladies are 5 feet tall without the pots and are actually potted at a 45 degree angle or would be over my head.
These are probably the biggest plants I have grown under these lights.

Can you please stop posting pics and get back to the discussion?

The same topic got discussed a couple weeks back on the IG account from Seedjunky - and quite a few commercial producers chimed in and are switching back/staying with HPS.
Pretty interesting to read their arguments.

Nobody ever said that LEDs can't produce picture-perfect plants.
It's about the resin quality they produce, why is this so hard to understand?

You can post your pics all day long in the picture forum or start a growreport, it is out of place here.
If you want to chat, use private messages.

It's a shame what happened to ICMAG, and it is even more so that you get more civilized and on topic discussions on Instagram than you get here.
Well done, people.

Good quality of resin is implied when posting pics in this thread, unless otherwise stated.

i printed the diode chart, did the ratio's and then colorized to get an idea of the symmetry.

thanks to vermontmans input i now know for sure for the first time what drives both mass building and high cannabinoid and terpene levels.

and they are not mutually exclusive.

also, the pics help us see and understand the differences in morphology in relation to differing spectra.

this light has demonstrated something i've read in papers and experienced personally using different frequencies of light

or at least one part of it, the visual part. we can't know the chemical outcome without usings COA's.

looking at the 200 diodes we see that 152 of them are red 630, which comes out to 76% of this light's output.

another 8% is 660nm so that means we have a light that is 84% red or 85% red if you count the 2 740nm diodes.

this is very close to the philips green power hps bulb that i have grown monstrously heavy plants with.

These percentages are off because almost certainly the different wavelength diodes produce different amounts of light. Would need to know diode models or better yet have spectrometer measurements for exact numbers but looking at some random diode specs on Aliexpress (same model, same manufacturer, same power consumption, different wavelength) 430nm produce a lot more light than 630nm, which in turn produce more light than 660nm.

Maybe add something then instead of referencing a public social media platform that anyone in a non legal place will never use to promote their illegal products.

LEDs produce quality product if you know how to grow with them, not much of a discussion. No one’s saying they’re better than other lights, they’re just new and different. You can shit on progress or you can figure out how to improve it. There’s a lot of people in this site that have and continue to contribute to that, coming in a thread and making a blanket statement then not backing it up with evidence or photos doesn’t fly.

Quality can mean so many things. I do not care about yield, terpenes, or looks. I want spacy upper type effects from the heirloom sativas I grow. So no red/yellow lights as that is not what happens in the equator regions they are from. White light and high Kelvin.

My strains are typically larfy and not sexy to look at. I am using LED as they are cheap and easy to use. I may try a metal halide at some point but then I have to change the bulb each year and use a ballast, some other problems with them. Going from flourescent to LED I noticed no drop in quality.

but i do care about yield, terpenes, and looks. but i also care equally about cannabinoid content.

I'm not done here yet! i will present some very interesting stuff later in the day.

everyone here including me has a set of personal experiences that they think proves their points.

we have all been wrong! some have been more or less wrong and some really wrong but no one, including me, has been really right.

yes, but i was just looking at the distribution of them. not relative power. but still, because of the distribution they are heavily red. and that is the point i'm trying to make. vermontmann's flowers were massively heavy for the light source and power. and i now know why.

here are a few pics of some of the plants i grew at my facility in oregon. i used sunlight supply DE's with the Philip greenpower bulb. i just showed the distribution graph.

Please notice that there is just one stem under each.

you can see that the bud structure i got here is eerily similar to vermontmann's. what does this show? the value of photographs? just joking!

it shows that the spectral distribution is similar.

@snakedope, buddy, this is why you see the differences you think you see!

there is a big difference though, between vermontmann's pics and mine. i use a better camera? no, that's not it!

he acheived those huge flowers with a cheap ass amazon light and i got mine with $600 dollar fixtures.

of course my plants are heavier overall because of the sheer size and light power.

also, i had 49 of these lights and because of that, i had to run 225,000 btu of cooling.

which is 4591 btu each.

even if he gangbanged 5 of his lights together to equal one of mine i bet he wouldn't use more than about 2500 btu's of cooling.

that's why LEDS!

Please my man why are you disturbing LED growers solid 100% proof lights... Don't embarrass them, you won't get out easy from this ;)

Well done, people.
Let them post their pics, they feel fine with it, bashing people, posting irrelevant info, they are masters at this work, on the subject at hand they all stay mute and cant take it in slowly
They buy 600$ worth of lights and fail, then buy 100$ of light and succeed, it's really voodoo magic those LEDs, make sure you cast the right spell when turning them on.
And on a serious note, don't expect a meaningful debate or subject related info as they are too busy finding excuses for their high priced vegging machines.

Well it looks like it's a 43 page discussion, so you are wrong about the quality, just wrong. if you accept LEDs grows as high quality the problem might be you, who knows ?
Go invest a 1000$ and learn how to improve it by buying a 1500$ system a month later.

LEDs are a joke, people who praise them just forgot real science and like to believe sales pitch more then logic.

Vermont man, your buds looks great by looks, it really do, but it's medicore weed, Im willing to bet on it.

The whole reason LEDs get such a push in every aspect of our life is cuz they are sponsored tech, go read research about this light and what it causes to your eyes, your dna, your ability to metabolize,
And guess what, you are not so different from plants.

Now think logic, think about the real science behind resin and trichome production
The 2 most important things, are light intensity and heat, both LEDs don't have.
Now let that sink in... Your light arrays don't have the 2 most important thing for the MEDS we look for...
Starting to recognize a pattern yet ?
No ? Well maybe you are just a Sheep.

They don't want you to grow good effective meds, they want you to grow beautiful plants with no medicine on them.
And if you don't believe this, youreally haven't researched nothing in the LEDs field and your opinion is not worth the time reading it.

jesus fucking a christ! snakedope, did you not read any of the above?

Delta, I respect you as a man and a grower, and you are right about less heat, less power expanse, etc
But please keep in mind that everything in life is balance, LEDs don't have this balance.
So you have less heat and less power consumption but when you give something more, you take from the other,
Your advantages are the meds disadvantages.
If you refuse to understand that this is the truth about those light you just live in denial.
Again, LEDs can grow awesome plants and very beautiful, they can't grow good meds.
So if beautiful plants are your go to then grow bananas or papaya or some, cuz meds are not growing on those beautiful plants.

below is the approx spectral distribution of common led screw-in household bulbs.

the 2700k color temp is pretty close to a philips greenpower.

i'm using 2700k and 5000k bulbs in various ratios experimentally.

in the grow experiment i'm doing now i started with all 5000k bulbs,

at 2 weeks i went to 38% 2700k.

at the flip i went to 66% 2700k.

now i'm nearing the end of stretch and i think i'll bring the red ratio up to about 75-80%.

more to come later!
