LED vs HPS: Grow Lighting in 2024

[@jamesdarkride7588]

Hps is less efficient I’m sure but grows higher quality product. I’ve tried both ways many times to compare. I actually like a mixed spectrum of led and cmh, led’s by themselves just don’t do what a hps can, mix the two and see if you like the outcome

[@jimdough2018]

You miss an important factor: many strains have been selected and bred under HPS, some varieties just love HPS like Skunk genetics. Also many LED manufacturers try to compensate for the lack of far red photon output an HPS can deliver and UV that a CMH does deliver naturally. Consider mixing lights, adding a HPS in the last weeks does wonders for many varieties.

[@osho5996]

I think they're talking about growing veggies 🤣

[@justinmynatt896]

Question... If IR "does nothing for the plant and is of no benefit", then why are most modern LED manufacturers now adding IR specific diodes to their fixtures?

[@theomarvenzon]

cause they will say anything to make a sale...they say the same about uv but got uv add ons now...why buy separate light systems to match what hps already does...they say led is more efficient but buying whole new led lights cost more and utilize more natural resources to manufacture than replacing bulbs that can be recycled

[@MIGROLIGHT]

IR or Infra Red is 750nm or greater and is radiated heat. Far red is 700nm to 750nm and is somewhat photosynthetically active. However there is not a lot of evidence to backup adding Far red makes sense. It can cause stretching and is not as photosynthetically efficient as deep red at 660nm.

[@Alapahauk]

8-15 mins of far red at the end of 12/12, increases trichrome production.

[@theomarvenzon]

@@Alapahauk so it is simulating the very end of a warm autumn sunset...very interesting

[@RammaJamma3]

Am led but several big grows in U.S are going back to HPS or half and half led HPS. I’ve watched them talk about it they say walk outside stand in direct overhead sunlight do u feel how hot your getting their saying that has something to do with it

[@dantheman6698]

theyre right, the leaves get hit with sunlight that contains IR then have to lose water to cool down, this lost water is replaced by sucking it up from the soil and it sucks up nutrients with it. if they get hit with high levels of light but no IR then they dont lose water as fast and they run out of nutrients = sick plants. increasing ferts helps but its impossible to get it right.

I will slay any LED grow with HID. I’m not saying LED sucks because it doesn’t, at all. It’s great for many reasons. But, pound for pound, quality of buds from HID is superior.

Anyone who has eliminated HPS from their toolbelt has lost an important tool I grew cheese from Barney's Farm under LED three times I was never happy with the results -so I tried it under my old HPS Let me tell you it is a different animal, likely because it was developed under HPS Those who say HPS is useless, have not run enough strains 😊

[@Memflix]

as explained by many old time gurus of the world cannabis, most of the existing genetics are the children of those 4-5 genetics developed between the 80s and 2000s with exclusively HID technology, so today we probably still see a difference in plant development between LED and HID based on the genetics. I have been growing for 30 years, I have worked in the lighting sector for over a decade, I have frequented Holland for 20 years and I have seen many types of weed in all possible crops, but the best results, the plants with the best developed flowers I have seen only under a combination of HPS600W-LEP300W, that combo seems to emit a light particularly appreciated by plants! The CMH630W DE dual spectrum produce a light very similar to that combination, with 2 additional LED bars for UV and far red in my opinion we are close to perfection, without having to spend thousands of euros for a corresponding LED lamp.

[@deleqtronica8733]

No one says it's useless, but it's nowhere near as efficient. If you enjoy paying more for less, than keep doing whatever you're doing, no one is stopping you.

[@cjmarch30]

Efficiency don't grow buds. Why are the LED producers putting out IR/UV bars? Cause those are the parts of HPS environment they're STILL missing. Keep your efficiency- I run LED and HPS. Use what's proven best for each strain. Same to you, keep yours.

I still like HPS in January and February where I live. My house has electric base board heaters that are RIDICULOUSLY expensive to run. The HPS actually provides the perfect amount of heat for my grow room during those two months. Any other time,tho,I use LED lighting. Do NOT use digital ballasts for HPS. They’ll blow your bulbs. Digital MH are fine.

[@peckerpeter2078]

Incorrect, your digital ballast is blowing bulbs because you’re using the incorrect bulbs for your digital ballast…!!! Digital ballast are more efficient, then magnetic magnetic will last longer though .. HID digital ballast high-quality with the correct MH bulb for veg. These are not dimmable at all so Use 600 W bulb for 600 W setting etc etc… HPS is to be used in the second or third week of flower I wouldn’t recommend dimming that either you can dim, but it will degrade the lumens faster …. Problem is the manufactures put out great products but they never put out how to use or operate everything correctly which left a lot of operator error and then think the product was garbage because they didn’t use it correctly ….

I use digital hps since they came out. Zero problems. Run them full blast though.

Back in the hps days you could make it work because there was no dispos and u could make your money back still have flowers left for yourself and all worked out cuz u could make a few grand or more if u had the goods so that big huge electric bill evened out in the end. I wouldn’t have recommended any equitorial stuff back in the day with an hps. probably another reason everyone steered towards the broader leaf flowers shorter time so less expensive bill. I was always not a fan of that so it got expensive having a 16-25 weeker going after a 2-3 month plus vegative stage back when I was as into the gardening thing

MH/HPS anit going away, Great growers were getting 2-3lbs per 1,000w of Straight Dank. You can’t blame the light (blame the growers) when you don’t have a full 5ft x 5ft canopy 2-3ft deep. (Min 4ft x 4ft 2ft deep )Which is 1.36 Gpw For HPS, best LED with top growers getting 1.7gpw. LED diode always burn out been dealing with LEDs since the 2000s… You can look at these so-called LED growers with these LED lights and they’re already on their sixth or seventh different brand LED light claiming it’s still the best.. Mh/Hps produces the highest quality hands down with a competent grower. With efficiency SOP’s used, HPS would still be more efficient. Than LED’s (mainly not needing an extra dehumidifier.) Electricity prices are inflated, which makes it difficult to use HPS/MH and even LED as they pull about the same wattage to be equivalent to each other.

i had to go back to hps because led lights have a massive flaw, they dont have enough IR and the plants suffer nutrient deficiencies because they dont get warm leaves, transpire and suck up enough nutrients. led's are super good at making light that plants like and work the leaves very very hard but if they cant suck up nutrients to sustain it then it harms them. i watched so many different types of plants and trees suffer under led. a sunny day blasts plant leaves with IR, hps, mh, cmh, blast leaves with IR in a very similar fashion. led doesnt. shane is misleading people that IR is bad because he wants to sell led's. what shane should be doing is making his light fixtures have MORE IR leds, much much more, probably 50% of total wattage should be IR.

HPS is worse in every way possible.

Efficient? Ill double LED yeild with HPS, bigger better buds. It really is that simple. My shit will sell way faster, hands down. Side by side I used LED and HPS... HPS allowed closer to plant ( cool tubes) and bigger bud with greater yield. LED I still needed an AC unit, I also needed greater ceiling height. Plants grew great but I didn't get the 1 liter bottle size buds... Cost to operate the light wasn't much different maybe 2 amps. The entire set up needed all the same equipment. However, the LEDs did keep my plants shorter. I will use both. Don't forget folks there's an energy war going on. Also the lighting industry screws everyone. Remember when the LED light bulb came out? Lol whatever " "bro" Here buy my $1200 light ... Because its better. If it were better it would cost the same. These jokers are salesman. Just think about all the people that bought LEDs 5-8 years ago.... They're all shit now.

[@stangmann1521]

Check out GML LED lights & you can have both light spectrums / HPS by dialing in the light spectrum / You can adjust and change to any spectrum you like with use of Top- shelf best diodes available! ✌Best lights on the market IMO 💪

[@milkybaravenger]

It’s a no brainier in the EU already phased out t5,t8,cfl, halogen and metal hailed for LED and in two years they are phasing out HPS and the last fluorescents. No point in paying for a light that’s being phased out plus better efficiency and less heat it’s win win.

As Shane calculated, the more seriously one grows, the cheaper the led will be. But not everybody agrees with Shane - i do! Some are still convinced that hps can grow better flowers for ex, and if they mean by that much less leafy, i'd totally agree. But others would say that the flowers are more compact with led, and that those leaves are also valuable, and they'd be right too! For what is worth my "best" grow was under hps and a cheap magnetic ballast, it was a giant Zulu plant from Drakensberg, with huge internode, and i never reached smt comparable with led since - i heard that breeders can have the same issue but these are very specific

[@Hansen710]

all those factors are not the light its the inviroment if you are in a northern climate a led is not creating the heat needed for example everyone that is not blind can see a hid do have more natural light but that does not help if your inviroment gets worse just the fact that hid grows bigger buds under optimal conditions says everything, the plants feel better dont listen to anything shane says, all logic is out the window with that man he is shilling led and not selling facts just look at the old videos the led´s that was half as good as today was better then a hid according to him he removes people that commeent with facts to make his logic stick

[@britishgass6947]

Led does not save you money. Shorter lifespan of the fixture much more humidity to deal with and more fertiliser required just to name a few. And if you look at the fact the best indoor producers in the industry have been returning to hps or mixed spectrum rooms. No disrespect but asking a led salesman which is best you are going to get the sales pitch. Speke to growers who have real world experience of these things. I have ran next light mega 1 and 2, fluence spyder 1 and 2, all spectrum king range, hlg quantum boards, Lumatek zeus pro, maxi bright, gavita ct2000e and revolution micro avicci led’s not to mention the blurpels of 15 years ago. Led is good but not better and it is definitely not black and white like some people will have you believe

[@MoonWind32690]

Hoocho! I've loved your work for quite a few years. I finished a 4 year Horticultural Science degree and for my last two years I did hydroponics LED & PAR research projects for my projects. In doing so I figured out how to design and build my one grow lights. In the process I found research from Dr. Bruce Bugbee : kzbin.info/www/bejne/f3umfat5j5qkqKs His work is fundamental if you want to get into more of the complexity that Shane touches on! Dr. Bugbee does an amazing job of making complex subjects understandable and provides cutting edge information. University of Michigan also has a fantastic LED lab that has posted some great papers on tuned lighting for controlled plant life.

This is very old news. HPS are worse in EVERY MEASURABLE aspect. Hotter, more expensive, fire hazard, far more equipment(ballasts, hoods, ducting, fans), vastly shorter lifetime, ugly light that makes it hard to appreciate/diagnose plants, narrower spectrum, fewer features on the light itself, no progress in the technology in decades, etc....., etc....HPS is inferior with literally no benefits of any kind.

[@BudgetNugs]

Literally no benefit is a bit extreme. You right about LED being better in almost every way, but in very specific circumstances it's better to run HPS like in antarctica. The heat released would possibly save you money on heating.

[@diezelvh4133]

I'll put my quality hps dank up against led crap. I steal a customer from led growers and dispensaries every time they try it. 😊
