No. It’s not. You agreeing with facts doesn’t make facts your opinions. Lol

De hps has more plant useable light than any other fixture on the market afaik In a 5x5 space. Uv and ir have been proven to increase potency up to 20%. I don’t care what any of you bro sciencers think about your lights. Real facts and data are what I’m interested in and I have yet to see a single all white led panel do what a single 1k de hps or cmh bulb can. I run all These lighting types. I tested all of hlgs stuff in prototype. I actually have tried and tested all These, I don’t just go by what I read here. And I’m not talking about watt increasing efficiency because I don’t care about that. I want more light in my space and more weed that the most potent it can be. Maybe that’s where the difference lies. Most just care about what their plants look like. And white leds are a significant amount easier to keep plants healthy under than hids. I think if most guys could keep their plants healthy they’d understand generally light isn’t the limiting factor, but things like uv can change potency A LOT in weed, regardless of how pretty you grow it. Genetics are genetics.

Give it a rest big lad.
Show some manners Mr Warrior.
You need to smoke something stronger pal because you need to relax and also sort that shit as fuck attitude out.
The weed is not doing for you sweet pea.
Now, toddle off and really try to enjoy your day, stonees usually do so don't get it.
Geez.......... So sad
I totally agree but the fact remains that hps is a very narrow band it does have it but doesn't outperform quartz in that spectral range otherwise emerill would use hps instead of quartz which Sylvania currently runs best what a lot of people don't understand is there is a lot more money in lighting ballfields and such than there is lighting gardens this is why eye hortilux couldn't hold Philips, Samsung's or slyvania's jock strap I am not against his I just don't currently have a need for 550 to 650 nm got that covered

Ive grown with all sorts of lighting.. Including CFL, 1st gen Blurple LED, HPS, MH,CMH, and most recently LED COBs with supplemental deep and far red, and UVA & UVB and 365nm to boot. I vegged her for 6 months in a 3x3x7 and she is huge !!!
I used to swear by a 600w HPS...and to be fair they are still great...but LED means smaller fans, less noise, better spectrum and no need for expensive reflectors and ballasts that can take up a crap load of space...or need additional cooling.. For a fraction of the wattage / running cost .. I can get similar result from my current LED setup running 550w.. ..That only 50w less than the 600 but am running 19 seperat led fixtures as apposed to jus 1x HPS..
The plus side to HPS is the intensity...but if you dont care how messy or crouded an LED rig can get..and like me its purely personal smoke... Then you can arrange the LED lamps etc.. In a way that LED penetration is no longer an issue on bigger plants..
So LED gets my vote...but only new/next gen LED not blue purple chinese crap that kills your eyes and doesnt give good results at all...blurples suck imo..
I am interested in the progression of LED Horticultural lighting...when that intencity is increased...I am sure HPS and other HID lighting will become a thing of yesteryear..
As it stands though LED is my preference for a non commercial 3x3 grow - STELTHY

LED really shouldn't be compared to HPS HID it should be compared to CMH HID. They each have their pros/cons. If you buy the hortilux CMH you will get a decent amount of UV light. CMH provides a surprisingly full spectrum of light with only a 15% loss of light at 20,000hrs. I bought 2 on sale for about $120 and they should last me close to a decade just using them in flower.

900 grams under a 630w fixture in a 5x5 (4 plants) no C02 supplement.

Who uses glass on their lights in a big room? I use led hps and cmh. Hps yields most hands down. I mix cmh in for added uv.

In practice. De hps outperforms everything. Haven’t seen enough 1k de cmh to compare.

We use .
DE 1150w Gavita, Gavita 1700e LED, 1000w Hortilux HPS, D1000w Nanolux DE CMH.
IMHO the best one is the 1150w Gavita, but is extremely hot, and you have to have it at least 36-40 inches above the canopy. DE CMH also needs to be that far.
We also supply 2x 32w x 4ft Solacure UVA/B Flower Power in each 4 x 4 area. we use 3 for the Gavita, and 1000w CMH.
The Solacure is extremely powerful, and goes all the way down to 280nm.
Under the 1000w SE Hortilux, and Gavita 1700e we have them on 8 hours a day in veg, or flowering. We leave them on 12 hours in flowering for the Gavita 1150w,and 1000w CMH because they have to be kept farther away from the canopy.
We also use the UVA/B from seedlings -veg, do there is no transitional period, which can burn them to death if given to much, to soon.
We veg 24 hours but give the same amount of UVA/B as in flowering. There IS a notable difference in potency vs No UVA/B. Everyone that has smoked our weed agrees it better than when we didnt use them.
1000w Nanolux has 1688umol.
1000w Hortilux SE HID has 1600umol
1150w Gavita has 2100umol
Gavita 1700e has 1700umol
The 1150w Gavita has 20% more umol.
All the others are optimal for a 4 x 4. The 1150w Gavita will cover 5 x 5.

No way does HPS grow dank any more. White Led is the king dude, you haven't heard?

Thank you for the first hand testimonial that to some growers out there who care about what they are doing Plant Quality comes before electrical efficiency!

Its just the facts. 1150w Gavita has the most umol of any light. LED or otherwise.

Hey @jimihendrix1 , guess you haven't seen this light yet. A little more expensive than your Gavita 1700e , but it is a 1000 watt light with a total PPF of 2,450 µmoles.

Both ChilLED and Meanwell are sold out of 480H drivers until July so this light is now on backorder.
The light was released a little more than a month ago. I believe @Snob is growing under the DIY kit version of this light.

You should look into the Ushio 5003320 - 2400umole's

Yeah but its $1700. Ive had the 1700e for 7 months.
You could almost buy 2 HLG 650Rs for that price. I got my Gavita 1700e for $1100 on sale
I got my 1150w Gavita for $450.
Bulb for 1000w Hortilux HPS is $60. Whole set up for $350.
IMHO all of the best LED are way overpriced. Its one reason I didnt buy one for so long. For the money I still like the 1000w Hortilux. I can get 3200umol of light for $700 for a comple set up. And if you take of 10% initial light loss, thats still 2900umol
Phillips makes a Toplight Compact that draws 630w, and puts out 1800umol, but they will only sell them in lots of 40, for $32,000. $800 each if ya got $32,000.
Nothing beats HID for the $$$$$

De Spectrum is much better than traditional hps as well. I think a lot think hps tech isn’t also moving along with led and metal halide. I’m still pretty sure a lot of people get a good led panel and see what healthy plants actually look like and assume it’s the leds, not the spectrums affect on how efficiently the plants take up nutrients, easier to manage heat levels, etc, that make mj Easier to keep healthy, and home environments easier to manage in height or heat restricted areas.
A light is a light just because it less efficient doesn't mean we don't compare hps does have many advantages it has just been passed up just like all are leds now will be I just don't see why everyone with the exact same goal can argue so much over an industry that really doesn't care about us and all products are tested and output is recorded I a side note an hps has a lifespan of one or two grows cost 100 bucks approximately same as a Diablo in process of having a high dollar heat sink made with a proper thermal interface we are going to see what Samsung is made of at this price point I will melt those LEDs right to the board lol
