LED vs H.I.D

I think both yes and no on the wide spectrum. If this was true then all outdoor weed would be superior to indoors and fetch a higher market price which is not quite true.

I’m going to have to disagree with you on the wide sun-like spectrum. Filling the cyan/green gap that is lacking from most traditional LED spectrums, is something that I’m working on right now and plant response is great so far. But when I was referring to broadening both ends of the spectrum, I was referring to blue/violet/UV nanometers and also deep red/Far Red nanometers. Like 365nm- 437nm & 660nm - 730nm, that are typically missing or minimally present in most standard LED spectrums.

I should also clarify when I’m talking about quality of plants grown under sunlight vs artificial light, I’m personally referring to indoor vs greenhouse grown, not just “outdoor” grown. Which don’t get me wrong, I’ve had excellent outdoor and excellent indoor herb. Outdoor grown is at the mercy of Mother Nature though. So if you don’t live in an ideal climate/environment, your end quality is likely to suffer some.
But, consistently the very best I’ve ever had has always come from soil grown greenhouse weed grown under the Sun, and it’s not even a close competition. The terpenes are so much more diverse and pronounced, the flavor seems to almost always translate through the smoke, and the high seems to last hours longer than indoor herb.
I’ve even seen cuts that myself and buddies ran for years indoors under different types of lighting look, smell, taste and feel very different and better in every way when grown in living soil in a greenhouse, under sunlight. It was unrecognizable and amazing (707 Headband). I’ve seen it personally a number times, and studies support what I’ve personally experienced.
Market pricing has nothing to do with how good the weed actually is unfortunately, at least in the States. Pricing is based on bag appeal, test #’s and the hype of the strain and that’s literally it. Not the nose or the taste or the quality of the smoke differentiates pricing. Here in the US, weed is legal to some degree in a majority of the populated states, but we are flooded with so much boof herb that I can’t take $1000 around town hitting up dispensaries or dealers and find good weed. There almost is no good weed on the market, just check the forums and see what older heads think. The market will buy what’s being provided, and currently that is mostly boof, but it’s priced as if it were actually good. I guess a majority of consumers may not actually know the difference between meh bud and outstanding bud.

Regarding your lighting tests, it would be cool to see the broad red from the last spectrum mixed with the double blue peak from the first spectrum. I’m hoping to be doing something similar in the next few months, but utilizing a number of different strips. Please keep us posted as you go!

Agree with everything here, only i dont consider the gap to include green (550ish), its always high in white phosphor diodes, but cyan 475nm should definitely have a place in supplementation its just that it is impossible to find efficient diodes.
I have 4 triple red supp versions im testing against eachother (if all goes well) for more clarity in how i like to manage red supp: 640/660/680 in different mixes with triple 660 as a baseline. But all of these strips made to have a separate blue/uv channel.
The first strip with 405 supplemented would actually be the broadest spectrum, 405 + 680 with narrowband phosphor for the rest otf the peaks. All of these are 90 cri spectrums which come with a slight efficiency deficit to the standard 80 cris but speced at 35-40w per sq foot, and with a more flower centric spectrum i doubt that it will matter much.

I use 2 of them, with a 1000w HID, for each 4 x 4 area, at 24 inches, and slowly build up the duration to 4 hours per day, but also still watch at the reaction the plants have to it. I also use often use a Blue Heavy Hortilux Blue or similar type of bulb for flowering, with a 6000k-6500k spectrum. Which the Halides, also release 280nm of light. All the way to 2400nm+. I use the Solacure, to intensify the lowest spectrum. I also find it useful with 1000w HPS-Hortilux to enhance the lowest spectrum.
Also at 280nm, it has been shown that it will reduce/eliminate powdery mildew. 280nm, is the line of UVB/UVC.

I used a Hortilux-Super Blue MH for Veg and flowering

Since the 80s, even today this bulb is used in professional horticulture across the board.
250.00 bulb. Ballast doesn't cost much, I've used the same bulb for years, I'd say every 3 years replace one. You can find the bulb 178.00

Simple reason why professional use them, plant health diagnosis, in any other light source deficiency will hide longer than the Hortilux-Super Blue.

Meaning You can see flaws better under this unique lights.
Terps explode strong, you'll get an exact replica of an outdoor grown plant.

The actual goal for a Cannabis plant. High and low K value stretch and shorter height, which for HPS this can shorten the stretch.

With the MH bulb. I reduce the stretch and get a more dense product. Even with color that HPS doesn't exhibit in the final product.

Since the 80s the HSB bulb is the greatest light source other than the sun.
I Super cropped a 2 limb plant day 1 flowering, the mains are on the left and right outside, the middle is the lower. This is penetration i would image what the description says about HID
1000000528.jpg

Then there's diffused light, MH in flowering, big buds everywhere, lots of lights spaced out, instead of packed in.

Have you ever seen the power of the right HID system?
How about a 8000k MH last week of flowering? 10,000K last days?

Weed was better back in the day, because it was grown better indoors than it is today.

The carbon footprint was way lower and a very efficient solution to Cannabis not grown under the sun.

Overfeeding will ruin potency and taste. Cannabis will never be easy to grow, but it's like printing your own money, and being in full control of your medical needs.

I haven't proof read above , my pancakes are ready.

If the Hortilux Super Blue really was the pinnacle of flowering quality, you'd still see them in use by winners of Emerald Cup or Spannabis. But most of them have gone LED, even the old-school breeders are switching over.

Most recent Cannabis Cup winners (2019–2024) increasingly use high-end full-spectrum LEDs

Some legacy winners from the 2010s did use CMH or HPS, often combined with heavy CO₂ and environmental control, but rarely MH or dual-arc bulbs like the Hortilux Super Blue.
Masonic Smoker, Compound Genetics, Jungle Boys, and Connected Cannabis Co. — known for top-tier flower — have either switched to LEDs or hybrid LED/CMH setups in recent years.

According to the 2023 State of the Cannabis Lighting Market report by Cannabis Business Times, LED lighting has become the predominant choice among commercial cannabis growers:

- 73% of commercial cultivators reported using LEDs for flowering in 2023, up from 15% in 2016.
- 62% of growers cited "crop quality" as the primary reason for adopting LED technology, surpassing considerations like yield (16%) and energy efficiency (12%).

DogHouse Supreme Cannabis, a five-time Dope Cup award winner, has transitioned to using Sunscape LED lighting systems. The cultivator reported significant benefits, including up to a 70% reduction in electricity usage and enhanced terpene production, particularly during the final two weeks of flowering .
 
Hortilux Blue really "Shined" as a Veg lamp.
Had certain circumstance gone a different direction on a global scale I am sure the conversation would be different at this point.
Just a few things I could have seen making a difference in the way tech has shifted - energy prices would have had to remain constant or go down (fantasy land), Lamps would have had to become cheaper to offset replacement costs vs lifespan of led technologies.
I love HID lamps myself and led's.
Only a foolish grower would ignore their wallet and when Hortilux shut down that was a nail in the HID coffin as far as I am concerned.
Sure there are some HID lamps still floating around in warehouses and grow shops out there but that supply will inevitably dry up.
Just look at the limited selection of HID fixtures available compared to years past. :peace:
 
This flower was grown under Hortilux Blue MH. No doubt the quality was supreme.
You would need more watts of the MH to match the ppfd of HPS and especially modern LED's.
Them Damn Utility Bills!!!

Very nice, the main quality a SB gives is outdoor quality flowers. Diffused light from Mylar and big hoods help overall to lower cost and raise yield.

The HORTILUX™ Super Blue lamp is environmentally friendly in that it passes EPA, TCLP test criteria as non hazardous waste. We did test with 12,000 K MH and increased potency and trichomes the last 8 days.

You can use a 10,000 K too.

I like 4600 to 4800 K MH in flowering. It's like holding and smoking an outdoor grown bud.

But for practical sense with the state of energy costs unfortunately Metal Halide is from a Bye Gone Era. :(
Trust me, I also held on till the end with HID.
Hortilux throwing in the towel and stopping production of all of those lamps was the tell tale sign where the industry is headed :peace:

Hortilux-Super blue bulbs, specifically metal halide (MH) lamps, are used by professionals in plant physiological research and the biotechnology/pharmacology industries.

They are also utilized by individuals in indoor plant growing who want to replicate the benefits of natural sunlight.
Why i use them for an exact replica of an outdoor plant grown indoors.

These bulbs are favored for their ability to provide a balanced light spectrum, optimizing plant growth and yield, especially during the vegetative stage.

Plant Physiology Research:
Hortilux-Blue lamps are used in scientific research to study plant responses to light, photosynthesis, and other plant processes.
Biotechnology/Pharmacology:

These lamps are also employed in biotechnology and pharmacology to grow plants for research, medicinal applications, or for the extraction of compounds.

The Hortilux-Super Blue will never go away, they haven't thrown the towel in yet.

Bulb and Ballast are very affordable compared to other methods. I get about 4 to 5 years of use from one.

About 300 and you get a great light system. I've tried LED , but I use a 4 foot 5000 K LED shop light to raise plants in veg. With reflective material mylar or Aluminum foil dull side out.

I save a lot of money and the plants look better than any method I try. Including HID and big LED light.

4 to 5 inches of soil in pots, this one is in the transplant stage, now I can put the plant into the garden or transplant into a bigger pot.

Sometimes I just add more dirt below, pull the plant up and add it below, They grew super fast this method.

I had 2 1000 watt HID and the heat going for the home from winter and the bill was 300 dollars a month.

I dont see hardly a difference in my bill using them.

"Eye Hortilux, a division of EYE Lighting International, ceased operations in mid-2023. The company announced it would wind down due to supply chain issues, rising costs, and a shift toward LED products, which made continuing their HID lamp business unsustainable. They stopped accepting orders for assembled items and focused on selling off remaining inventory of Eye Lighting and Hortilux branded products.However, there are conflicting indications from some sources. For instance, Hortilux's website (hortilux.com) and related social media presence suggest ongoing activity in providing LED, HPS, and hybrid grow light solutions, particularly in international horticulture and indoor farming. Additionally, products branded as Eye Hortilux are still available for purchase through various retailers like Amazon, eBay, and hydroponics suppliers, though these could be from existing stock.Given the closure announcement from reliable sources in 2023, it’s likely that Eye Hortilux’s U.S. operations have shut down, but the brand or its products may still be active through international divisions or remaining inventory. For definitive confirmation, you could contact Hortilux directly via their website or at 877-905-2562."

Maybe you have some insider info that the rest of us are unaware of regarding Hortilux lamps still being produced?
If so, please do shed some Light on it! :peace:
