I think additional treatment will still be necessary.

My thought on this is most high-quality LEDs already have chips on the boards for the light spectrum we need. If I was a commercial grow and Money Was No Object I would have no problem spending investors money on the best lights available. Since I am just a very small home grower I feel that there are many lights that will suit my needs perfectly without breaking the bank. With the cost of quantum boards, mean well drivers, heat sinks and wiring a person can build a very high-quality light and be into it for much less than most of the name brands that are using the same components. I just picked these up to start my next light build. I will have a 240 W LED light built for less than $150.

Not in things like cannabinoid content, potency, or yield.
Unless growing vertical maybe, i can’t think of a good reason you would turn your light away from plants?
We’ve already pointed out that this light is lower performing than others that are half the price. Hlg, chilled tech, fluence, timber, and probably many others are a better value.

Wall to wall, corner to corner in my 4x4. It wouldn’t change in a 5x5.
Scorpian Diablo with FGI UVA and Far Red 4ft stips.
All I’ll ever need!
I’ve never heard of this other company before today! LOL!
Go for the best and you won’t be disappointed.

There is so much taken out of context with your post. Just because people can and do add supplemental wavelengths to their leds doesn’t mean they have to.
I’ll post 2 pictures in argument to rest of your post
Eye hortilux super hps 1.25 umol/joule
Hlg scorpion diablo 3.2 umol/joule
Hps is absolutely cheaper to purchase. But it’s not cheaper to maintain same canopy intensity or maintain over life of ownership. And i definitely dont see the extra red or uv in the hps. If anything it has significantly less red light.

Great summerary above of course.
Efficiency is way better with led, be it boosted with uv or reds or far reds or not and fancier boards come with that all built in now (Infact kingbrites been doing this a while)
So that brings us to the heating issue, the cooling issue and then of course safety issue with HPS vs led.
Ontop of the spectrum and the cost over lifetime…
Then we have studies that show higher cabinoid profiles when using led vs HPS.
The only thing HPS wins at is up front cost, if HPS setups can be obtained freely then sure grow some bud with it but long term it’s better to run a led even if a supplemental space heater is needed.

I think it would be safe to say most don’t add it for no reason, so they think they need it. I have only seen great results out of Cree Cobb LEDs so far. The expense of a great led light especially if many think they must add additional red and uv light would be higher than alot of people’s yields here on two crops.
Hps needs air in summer but led needs heat in winter.
Most think they have to have led after reading forums but then they go buy a cheap Chinese light that no where near matches a HPS, go figure.
Don’t get me wrong if you got the money a led light can be had without the extra uv and red light, but with significant extra cost. I wonder if we will have to have more lights in the future or more uv to make the led better. Time will tell

If i was the type to make assumptions, i would say most add it because they read someone else posting about it on the internet lol. Everyone is going to qualify this type of information differently. If you’re going to claim anyone “needs” it, my rebuttal would be they think it will be an improvement. Either way, i posted current flagship light from horticulture lighting group and the most well known horticulture bulb available. Are you able to point to where the uv and red is in hps bulb that isn’t in the leds?
I think you’re smart person and talented grower, so leaves me to wonder where the disconnect is from post above to looking at actual spectral distribution graphs? To me, it comes from a lot of watching what people do and comparing to how and why they do it. I don’t think I’ve posted on here a single time suggesting everyone run out and buy uv bars or far red. People will ask questions and i’m usually pretty happy to share any info I have. But I’m not a believer that any of this additional light is needed to run a successful grow.

Also if you’re using a sealed hood with HID like the glass covered ones, that glass is significantly cutting UV from the bulb, from what I read on the internet!

Very true, but they don’t really have much for uv output to begin with. Uv is much more common in horticulture tuned metal halide.

Those are for rookies. Those that have no idea how to properly set a room up for cooling, to grow cannabis.
I see the specs on the chart but alot of people keep adding uv to led setups for some reason.

Because science Bro!
Very Likely: UV Can Increase The Production of Terpenes in Cannabis Plants. Like with human skin (i.e. sunburns), cannabis plants are damaged by exposure to UV light. However, if the plants only receive a small, tolerable amount of UV light it can trigger defense mechanisms that may be appealing to growers.Nov 17, 2021
It’s up for everyone to decide for themselves, and they will, but this is something I have personally seen happen with clones from the same mother, taken at the same time and one flowered under supplemental UV and the other not and the SCIENCE holds true - the UV exposed buds were much more resinous and sticky and much more potent.
I’m not trying to sell you on it, not to be rude but I’m the one smoking my weed so i want the best possible weed I can grow to smoke. I couldn’t care less what you smoke!
I’ve seen enough proof with my own two eyes to justify a one time expenditure that will be paid for by harvesting more than 1 ounce during my next grow!
But it’s better than that because on my next grow I’ll bag up enough dank stickiness to buy 20 + of them if I want! But I don’t need 'em, cause I already got 'em!
Everything in life is an anecdote until it happens to you.
