Anyonone finish a grow with the emerald green spectrum yet? Just ordered the 880w and a controller. Apparently just in time because they just raised the price of the light. Anyways, been growing a while with a homemade 8 bar light, just trying to step my game up a bit. I’m curious to see what difference the spectrum will make. I have mac1 caps cut midway through flower now. Hopefully I’ll have the light by the time she’s done, so I should be able to make a good comparison.

Im not convinced that more green light is a home run in flower. In our test grow we didnt see much effect of adding UV on green heavy spectrums but we did see an improvement in smell/quality when adding UV to a red heavy spectrum. But id need to see several runs like that to draw solid conclusions.

The light does not come with any uv. My homemade rig is a mix of 3k and 3500, some 660, 630, 2 royal blue and 4 uva diodes. At only 4 diodes for uv, I don’t think I’ll notice any difference in that respect. At any rate, I’ll be able to blast whatever I’m growing with plenty if light.

From what I understand, the Mammoth, are closer to the spectrum of the sun vs other LED. Mammoth is 4800k-5000k. The SUN, is 5800k.
The SUN, is Green Heavy. And while the Mammoths do have a great deal of Blue, and Green, they also also heavy, on the Red, and Far Red-720nm.
I bought 2 of the 880w Mammoths, but havent used them yet. I gave them to my partner, and he hasnt used them. Yet.
We are still on the HID/1000w train, and have such good success with it, we are hesitant, to change.

The Hortilux Blue, is the closest thing to the sun out there, at 5500k. Plus the spectrum goes under 400nm, and more than 2000nm. LED is 400nm-720nm, at best. Really. Spectrum Wise, LED arent in the same ballpark, as Hortilux BLUE, or any HID for that matter.

HID also go all the way past 2000nm, as LED, only go to 720nm-750nm tops. Plus the Blue, puts out some UV, and Infrared. Plants see way more than the spectrum, that LED can provide. Im still convinced the HID, has a superior spectrum. Especially the 1000w Hortilux Blue.

Its true Red heavy spectrum, will grow bigger plants, and theyve known this since the early 90s. Bigger, doesnt always mean better, and its also theorized, you will get more genetic expressions out of HID vs LED.

I once saw a program on PBS, about growing plants, in this case flowers, in greenhouses, in Israel, who are one of, if not the leaders in Hydro/Horticulture, as they grow an insane amount of veggies, in greenhouses.

But they did an experiment where the infused the Filon, or whatever material the greenhouse was made of, with Red.

The used all thee same Tissue Cultured Flowers from Holland. One greenhouse, had red infusion, the other didnt.

The Red Infused, grew 3-4 times bigger, in the same amount of time. This is true. But also consider, they were still getting the full spectrum, and not mainly visible light, which LED are mainly. And Bigger, doesnt always mean better. Ive also read experiments that say plants grown under HID/UVA/B vs LED, have different chemical ratios in the plants. Ive seen PRO, and CON, but for me, anything that is closer to the sun, is automatically headed towards the front of the line. Its to me, only common sense that if one is trying to grow plants, the closer one can get to the full spectrum, of the sun,its a no brainer its going to produce the results, NATURE, intended for the plant to have.

I bet theres not 1 person on this forum, that grows, that would give almost anything, to have a small globe in your grow room, that was a real sun, emitting all the same spectrum, as it would produce in the atmosphere, without the heat of the sun, of course. Say the same as a 1000w HID, but the full penetration power of the sun, and the same Umol as the sun. As far as Im concerned, others MMV. But for me, the ultimate goal, for a grow light, regardless of technology used, is to replicate as closely as possible, the spectrum of the sun, in the earths atmosphere.

HID goes way more, into the nonvisible spectrum, and its a proven fact, that the spectrum we cant see, is very important to the plant. ALL HID, and he SUN, have the 800nm-2000nm spectrum.

But, I do believe, the Mammoth, especially for the money, is the best, most cost effective LED out there.

Also consider this??

1800umol, and NO CO2 ENRICHMENT??

The SUN, at its brightest, is 2100umol.

CO2,,,,, right now, is the highest its been in 20 million years. Current CO2 PPM in the atmosphere, was 421PPM, last time I looked.

Before the start of the Industrial Revolution, the PPM of CO2, was about 180ppm.

So why did weed grow just fine, before the industrial revolution, when CO2 ppm were a lowly 180ppm, and the SUN, was still 2100umol??? HHHHMMMMMM????

What little logical sense I have, tells me, the thing that allows high light levels, and low PPM CO2, is CONSTANT FRESH AIR FLOW/EXCHANGE, and theres so much of it outside, the plant cant use all of it, even though PPM is low, the constant refreshment, more than makes up for low ppm.

Ive used a 1000w HID, as close as 12 inches from the plant, and no light stress. I promise you, a 1000w HID, is extremely powerful, especially at 12 inches. BUT, I have extremely good, fresh air exchange. and all of the plants, are constantly moving. I start seedlings under 1000w HID, and have since they came out with HID in 1977-78. At 24 inches, and let them grow towards the light. Sometimes, I may lower it to 20 inches, if I want them to be more compact. I usually keep the light a bit higher for Indicas, and closer, for more sativa oriented plants.

We also use 2x 32w Solacure UVA/B Bulbs at 24 inches, in a 4 x 4 area, and a 1000w HID.

Years ago, I read an experiment where they took Columbian Gold, that was normally grown in the mountains, and brought it down to sea level, and it ddnt even look like the same plant as grown at altitude. One thing that may be is less CO2/Oxygen, and stronger Sun, and UVA/B. Ive seen experiments that have said UV, can inhibit vertical growth, and I believe it. But, that may be what it takes, for certain plants, from certain places on earth, to make their original genetic expressions known. And its also true, that environment, can make the same clone, express different genetic traits, depending on environment, Light Type. Medium, Temps, Air flow. One persons Chem91skva clone, may look, smell ect, totally different than the same clone grown by a different person, under a different environment.

"The sun spectrum" doesn't exist. I mean look at the sky at dawn and convince me that is 5000 K (ish).

Talking about colour temperature is rather pointless. Unless it is black body radiation you can have wildly different spectrum and have the same colour temperature. UV or far red can he added at will and do 0 to change that metric but are very important to plants.

And no, I dont want a perfect replica of "the sun spectrum" in my grow. It's too much heat and the UV degrades all equipment in sight.

based on what you wrote
i can tell that
you are obviously growing some extremely good cannabis indoors,

my brother used to grow with solis tek ballast's, 1000w hortilux hps bulbs, and 400/600w 10k solis tek metal halides(vertical bare bulbs) and his pot was fire lmfao

but

what i learned is that LED is far superior too HPS...

so screw talking about spectrums and colors and bla bla bla

plants have receptors, you have chlorophyll a n b receptors and UVR8 receptors.

the job of a chlorophyll a n b receptor is to turn photons into electrons.

UVR8 receptors dont turn photons into electrons, you emit UVB/UVA onto your plants foliage and this stimulates the UVR8 receptors and when you stimulate UVR8 receptors you get a increase in cannabinoids and terpenes.

with all this being said a 1000w LED light will emit more photons than a 1000w hps light thus allowing your plants chlorophyll receptors too turn more photons into electrons end of story.

and all you gotta do is find some lights like the solarcure you mentioned too stimulate UVR8 receptors and off too the races.

i will never go back too HID ever. screw CMH, screw HPS, LED is king.

Metal Halide, specifically a Hortilux Blue -6500k, and a DE 1000w Halide-5500k, both have wider spectrum than any LED, and its a fact, plants use a great deal of light, that cant be seen. LED only produces visible light. Metal Halide, goes all the way to 2000nm+ and down to 350nm, plus infrared, which some may consider wasted energy, but, the sun, produces a great deal of infrared.

Technically when you say LED is giving more photons, youre leaving out the photons below 437nm, and above 720nm-750nm. Metal Halide, and HPS BOTH produce very strong invisible light below 437nm, and above 750nm.
Ive also never smoked any weed, as good as I was growing in the 90s, under Halide, but the FBI got the strain.

Ive been smoking since 1967, and this suff was as good as anything Ive ever seen. And we have a verified Chem91skva cut, which has been measured at 32%+ THC, though that doesnt tell the whole story. But the stuff I had in the 90s, was so potent, it ran many of my customers off. It was grown under Halide, and Ive seen NOTHING grown under LED, or any other type lighting for that matter.

So, I know, for 100% for sure, Metal Halide, can grow as potent of weed, as any light source.

And the guy at MassMEdicalStrains also agrees, and he says he has experimented, and finds that more true expressions, like would take place outside, are better, under HID, and he spent 10s-1000s $$$$ on LED, and went back to HID.
He also says its strain dependent. And I agree. Just like some weed responds better to the Solacure bullbs, than others. Plants that come from higher UVA/B levels, respond better, than those that have not adapted to extremely high light/UVA/B levels.

Metal Halide, also gives off UVA/B, and does stimulate the UV8 receptor. Just dont use a glass shield in the reflector. The Solacure, is the most efficient/powerful.

While it doesnt show it, MH flatlines all the way to 2000nm+.

But the stuff I had in the 90s, was so potent, it ran many of my customers off. It was grown under Halide, and Ive seen NOTHING grown under LED, or any other type lighting for that matter.

So, I know, for 100% for sure, Metal Halide, can grow as potent of weed, as any light source.

And the guy at MassMEdicalStrains also agrees, and he says he has experimented, and finds that more true expressions, like would take place outside, are better, under HID, and he spent 10s-1000s $$$$ on LED, and went back to HID.
He also says its strain dependent. And I agree. Just like some weed responds better to the Solacure bullbs, than others. Plants that come from higher UVA/B levels, respond better, than those that have not adapted to extremely high light/UVA/B levels.

Metal Halide, also gives off UVA/B, and does stimulate the UV8 receptor. Just dont use a glass shield in the reflector. The Solacure, is the most efficient/powerful.

While it doesnt show it, MH flatlines all the way to 2000nm+.

Thanks for the info. Not an led vs cmh vs hps post though. Looking for people that have flowered with the mammoth emerald green spectrum.

i have never flowered under the emerald green mammoths but imho there are a gimick. "normal" led's already have ample green i the spectrum, there is nothing to be gained by adding more.
Even hlgs new Diablo is using mint green evo diodes. There has to be something to it.

They are more efficient than standard whites. Also you need something "new" to get their marketing spinning.

They use a photon pump with a lower wavelength. The phosphor converted white from it is shifted to lower wavelengths, e.g. greener. To get a certain colour temperature they require less phosphor, thus less conversion loss, thus higher efficiency. The disadvantage is that it is *a lot* of blue light.

Sounds like a good veg light.
