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.
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
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.
@ Do you have any specific “lab reports” you would like to share? I have a feeling that all you would produce is energy efficiency and rack system specific studies. I would love to be proven wrong though.
@ErgoCogita look up HPS vs LED by Debacco University on youtube. THC-A is much more abundant in a side by side grow (HPS and LED) when grown under LED. That's one I can think of off the top of my head that's easily accessible.

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 😊
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.
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.
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.
@@cjmarch30 lol when will you dinosaurs learn? It doesn't matter how much you throw a tantrum about it, it's never going to be true no matter how much you lie to yourself. What you said makes absolutely zero sense btw.
Dinosaurs have YEARS of experience that you should learn to respect. Just cause something goes over YOUR head, doesn't make it nonsense- just for you it doesn't . 😂
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?
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
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.
Shane am led but people trying grow best weed and for their self is not worried about efficacy. Now their is several big grows in US going back to HPS and some have went atleast led and HPS
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
yah leds do weird shit to the plants .. first of all .. ALL LEDs that use white light are blue diodes with a yellow (phos. coating) .. but HPS is plasma .. same as the sun .. the spectrum is off sure but i think its just the photons are more "natural" if you will .. almost as if it doesent shock the plants like leds do
@@THEREALTICKLEMYELMO you on point...leds are a waste of time money and medicinal value...its missing uv ir and wave lengths...leds are just tiny spotlights beaming down while hps are waves of light...thats the reason they need a vpd while they could take way more hps light
Really great to have this insight from Shane. Was so impressed with the previous video that I decided to buy the par meter from his website hooch buckets from yours and have it all shipped to the UAE.
HPS=Quality flower LED=Mids. If your growing cactuss or daisy's go led. If you want the best dank money can buy use HPS. Of course shane(Owner of Migro led) would say led is better lool
Hps will alwas be better to me. I compare led to hps and theres little comparison. The light produced is closest to the suns spectrum. The incandescent bulb was designed specifically with this in mind, over decades.
What are you talking about? It's extremely off the sun's spectrum. If you looked outside (and not living in some kind of Mexico themed movie) you'd see we get a pretty full spectrum from the sun while HPS are basically only red/yellow.
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.
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 ….
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.
Huh I got 2.8 on my last run, hitting 2.5 is incredibly easy with lm301h and osram reds lol All you have to do is look at a par map - you know a real physical measurement
@@John-w7g6n really? CMH is the closest to sunlight spectrum you can get get I’ve had great results with it and considering going back to it. I’m currently using a lumatek zeus 600w pro 2.9 and it’s ok but for me CMH is the best I’ve used and that’s comparing to HPS and all different kinds of led lights I’ve used. I actually still have a 600w HPS but don’t like the heat they give off, even in the winter it gets to hot in my 5x5 tent.
Well that is nice to hear. Was second guessing my decision to just use ordinary LED strips for my first system but Shane confirms I should just try it at 17:55. Awesome!
Yeah as he says tho red will give a boost to it can get super cheap led boxes now i used to use grow lush but think they don't exist anymore but can still get there lights cost me 120 aud to get a 600w equivelant led ( used around 150-200w) and had terrific results easily 1-2 grams a watt or havn't tried them yet but hear terrific results about spider farmer leds they are properly tested and really cheap can get some of theirs lights for under 100 aud and they have some really awesome automatic fan combos

I gust got a 660 watt light for 150 shipped on sale. Its not a bar style but still a insane deal. Medic grow has 800 and 1000 watt bar style lights for 300-500 depending on the model. They have great build quality and customer service too.
So how would this save you money then...? 😊 Just use a 1000 watt hps. A 1000watt led is going to roast your plants on full. So why buy something that powerful to begin with?
I will say that HPS used for supplementing light in a greenhouse in a cooler climate can actually make sense. If you need heat and light than it makes sense, but honestly you need 240v and a space big enough to justify the infostructure.
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.
I had a buddy (passed away 3 years ago) that made a living for over 30 years growing. He was a master at his craft. He was dead set against LED. I think if he would have got a chance to see the scorpion Diablo v2 he might have changed his mind.
theres a scientist on youtube here who studies cannabis .. your friend is right .. HPS still has better quality of buds and dense -ness lol but its not so much these days about quality of bud when picking lights ... its more about your elect. bill .. but also i got an entire HPS setup for 250 thats a 1000w setup and a 700w output led is needed leds per lumen or w.e its 70% the energy .. but that 700W led is 2000 canadian .. so for me not even remotely worth it .. if the led loses diodes most people cannot fix it .. hps bulb dies .. i change it lol
@@THEREALTICKLEMYELMO I'm having a easier go at it using LED than I did using HPS. I couldn't manage the heat from the HPS in my grow area. So far the plants are responding amazingly under the scorpion Diablo. Maybe one day I'll have a different grow area I can control the environment better.
@@THEREALTICKLEMYELMO we also had shane saying from the beginnig led was way better then hid and the other day he made a video about they was worse i remember shane when led was half as good as they was now and he was speaking aboout it as it was as effective as it is today shane is a scammer dont believe everything that comes out of his mouth i cant comment on his channel, he only have posetive comments on his channel we cant discuss what he is saying if we dont agree do doubt a hid can still compete with led in a northern climate, often alot of heating is needed for led and the hid also got rid of more moist in the air and no doubt hid have a more natural spectrum, its like comparing a old household bulb with a led. its a very limited spectrum and if you combine that with stuff like chemical fertilizer you get something with half the taste if anyone thinks their plants smell better with led they probetly just got a better growing inviroment. and one can see a led gives a less natural light with a limited spectrum. it is better then it was in thee start, but we still have a long way to go
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.
Wait I’m half way in, you missed the point. Can you grow faster with HPS? That’s all the HPS people care about. Every one understands efficiency and safety bla bla bla. Remove all the external stuff and just do a test LED vs HPS with basil.
Great collab, Dr. Bruce, MiGro, and growmau5 proved this many moons ago.. and i have bought hundreds of hortilux hps bulbs in my commercial travels coast to coast.. never again.
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 💪
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
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
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 : th-cam.com/video/IJCLxCZ5qrI/w-d-xo.html 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.
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
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.
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.
@@Generalumbongo i was just going to say this, cmh and hps still have their place in colder climates. I really have no dog in this fight and its a bit disturbing how fan boyish some of you are.
Shane aka migro has the best advice... and growmau5 who pioneered led lights here before anyone for the herbs... i know the topic well and educate people here 18 years 😅 samsung lm301b diode is what made it 700 watts to replace a hortilux 1000 hps.. i grow commercially so i know the topic years ago 😅
look at shanes old videos about thee old gen led that was half as good as the ones today he was shilling theem like every other scammer shane reemovs all the questions about th things he do. so much bullshit the other day he was showing people how to burn down their home while giving the plants toxic fumes (creating co2 with a candle light ) just to get a little co2 that would have to be vented out with the toxic fumes
No, 315 solo.. also cmh by philips. I talk lights for 15 years here, before migro.. which is likely the guy at the start lol... yep of course ha.. double cmh is too close, i used them 2016 and it grows the same veg as a 8 bulb t5 which uses 110 more watts... for growth it does add uvb which helps resin (for the plants they were made for hemp etc) the first pioneer is growmau5, who proved samsung lm301b diodes beat hps... its all documented so thats undeniable
@@marcussmart3275 I know a lot of 'premium growers', they threw their hps bulbs away years ago, some build their own led matrixes, some use off the shelf. None have ever even thought of going back

Shane am led but people trying grow best weed and for their self is not worried about efficacy. Now their is several big grows in US going back to HPS and some have went atleast led and HPS
shane is so full of crap
he removes peoples comments when they dont agree with his nonsense
LED is better, HPS sucks!
@AdolfoMussolini-wx4yk is that a challenge? You post yours, and I'll post mine. Prepare your cry closet.
Use what ever works for you best period ✌️
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
I use both style of lights. LEDs have won me over. My plants just do better overall.
I’ve been using led for years have tried loads of different ones and currently using a lumatek zeus 600w pro 2.9 and none of them compare to cmh.
Since i started growing under LEDs, my main ojective thing i took away is that i started to get Cal/Mg problems like never bevore.
yah leds do weird shit to the plants .. first of all .. ALL LEDs that use white light are blue diodes with a yellow (phos. coating) .. but HPS is plasma .. same as the sun .. the spectrum is off sure but i think its just the photons are more "natural" if you will .. almost as if it doesent shock the plants like leds do
Not to mention hps bulbs come with added blue spectrum...
@@diezelvh4133 And just enough uv if there is no glass between the bulb and the plants
@@THEREALTICKLEMYELMO you on point...leds are a waste of time money and medicinal value...its missing uv ir and wave lengths...leds are just tiny spotlights beaming down while hps are waves of light...thats the reason they need a vpd while they could take way more hps light
Really great to have this insight from Shane. Was so impressed with the previous video that I decided to buy the par meter from his website hooch buckets from yours and have it all shipped to the UAE.
Good decision 🎉
HPS=Quality flower LED=Mids. If your growing cactuss or daisy's go led. If you want the best dank money can buy use HPS. Of course shane(Owner of Migro led) would say led is better lool
You can not come close to 1000w hps. It's not possible... YET
Hps will alwas be better to me. I compare led to hps and theres little comparison. The light produced is closest to the suns spectrum. The incandescent bulb was designed specifically with this in mind, over decades.
I don't trust any information from someone selling led lighting.
What are you talking about? It's extremely off the sun's spectrum. If you looked outside (and not living in some kind of Mexico themed movie) you'd see we get a pretty full spectrum from the sun while HPS are basically only red/yellow.
You don't understand anything. LED > HPS
@@noxiusobvious4239hps have added blue. They have for a long time. Sun is red/orange going into fall. Hint hint
Does the outside look like a sepia filter to you?
Great talk.
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.
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.
Efficient or better? In terms of health and quality of plant growth?
Both! and better in any other way possible.
@@AdolfoMussolini-wx4yk wrong
@@ALEXZANDERMEJ Yes it is.
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.
Huh I got 2.8 on my last run, hitting 2.5 is incredibly easy with lm301h and osram reds lol

LED grown bud has less smell and is less sticky, basically low quality bud, I been growing for almost 30 years, DE HPS is still the best, 💯 facts !
Nope CMH is the best grow light hands down.
I tried cmh, good quality, slightly better than HPS, but much smaller buds
@@John-w7g6n really? CMH is the closest to sunlight spectrum you can get get I’ve had great results with it and considering going back to it. I’m currently using a lumatek zeus 600w pro 2.9 and it’s ok but for me CMH is the best I’ve used and that’s comparing to HPS and all different kinds of led lights I’ve used. I actually still have a 600w HPS but don’t like the heat they give off, even in the winter it gets to hot in my 5x5 tent.
HPS is not good for a tent, I use them in controlled sealed rooms with air conditioning, for personal usage I would use cmh
Great conversation boys, well done.
I can imagine the light bill every month , LED is better all the way around especially powered by offgrid solar
That's the next thing I'm trying to get into. Solar powered tent fully controlled
if you go solar there is no reason for led
CMH is the best grow light.
Well that is nice to hear. Was second guessing my decision to just use ordinary LED strips for my first system but Shane confirms I should just try it at 17:55. Awesome!
Yeah as he says tho red will give a boost to it can get super cheap led boxes now i used to use grow lush but think they don't exist anymore but can still get there lights cost me 120 aud to get a 600w equivelant led ( used around 150-200w) and had terrific results easily 1-2 grams a watt or havn't tried them yet but hear terrific results about spider farmer leds they are properly tested and really cheap can get some of theirs lights for under 100 aud and they have some really awesome automatic fan combos
I'm currently running 2 1,000 watt hps in a 10x10 room with awesome yields. I'm very interested in going led, but hesitate to make the leap.
LED flower looks better/good, but it's weaker. Only last 30 minutes. I'm converting back to HID.

I’ve grown with full spectrum LEDs and I’ve had statins test at 35.04%
Wow so much goes into growing lavender, no wonder it's so expensive
I gust got a 660 watt light for 150 shipped on sale. Its not a bar style but still a insane deal. Medic grow has 800 and 1000 watt bar style lights for 300-500 depending on the model. They have great build quality and customer service too.
So how would this save you money then...? 😊 Just use a 1000 watt hps. A 1000watt led is going to roast your plants on full. So why buy something that powerful to begin with?
I will say that HPS used for supplementing light in a greenhouse in a cooler climate can actually make sense.
If you need heat and light than it makes sense, but honestly you need 240v and a space big enough to justify the infostructure.
This dudes obviously never seen 6 giant tomatoe trees under 6 1000w hps....😂
This dude can be working for the government trying to kick hps out the market.
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.
Plants like heat.

I had a buddy (passed away 3 years ago) that made a living for over 30 years growing. He was a master at his craft. He was dead set against LED. I think if he would have got a chance to see the scorpion Diablo v2 he might have changed his mind.
theres a scientist on youtube here who studies cannabis .. your friend is right .. HPS still has better quality of buds and dense -ness lol but its not so much these days about quality of bud when picking lights ... its more about your elect. bill .. but also i got an entire HPS setup for 250 thats a 1000w setup and a 700w output led is needed leds per lumen or w.e its 70% the energy .. but that 700W led is 2000 canadian .. so for me not even remotely worth it .. if the led loses diodes most people cannot fix it .. hps bulb dies .. i change it lol
@@THEREALTICKLEMYELMO I'm having a easier go at it using LED than I did using HPS. I couldn't manage the heat from the HPS in my grow area. So far the plants are responding amazingly under the scorpion Diablo. Maybe one day I'll have a different grow area I can control the environment better.
@@THEREALTICKLEMYELMO we also had shane saying from the beginnig led was way better then hid
and the other day he made a video about they was worse
i remember shane when led was half as good as they was now and he was speaking aboout it as it was as effective as it is today
shane is a scammer dont believe everything that comes out of his mouth
i cant comment on his channel, he only have posetive comments on his channel
we cant discuss what he is saying if we dont agree
do doubt a hid can still compete with led in a northern climate, often alot of heating is needed for led and the hid also got rid of more moist in the air
and no doubt hid have a more natural spectrum, its like comparing a old household bulb with a led.
its a very limited spectrum
and if you combine that with stuff like chemical fertilizer you get something with half the taste
if anyone thinks their plants smell better with led they probetly just got a better growing inviroment.
and one can see a led gives a less natural light with a limited spectrum.
it is better then it was in thee start, but we still have a long way to go
LED is straight up better. Everything about them is better.
@@AdolfoMussolini-wx4yknope. High is generic and synthetic. Hps is super sticky, smelly, tasty, and a better quality high.
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.
Wait I’m half way in, you missed the point. Can you grow faster with HPS? That’s all the HPS people care about. Every one understands efficiency and safety bla bla bla. Remove all the external stuff and just do a test LED vs HPS with basil.
HPS is worse in every way possible.

Great video and very interesting topic...cheers
Great collab, Dr. Bruce, MiGro, and growmau5 proved this many moons ago.. and i have bought hundreds of hortilux hps bulbs in my commercial travels coast to coast.. never again.
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 💪
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
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
:)
LED bud is not good, HPS bud is much better, been growing for 30 years, last 2 years with LED, there all going in the garbage.
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 : th-cam.com/video/IJCLxCZ5qrI/w-d-xo.html
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.
HPS is way better than led because it is very intense and not for children!
Mitchell ay😂
Hoochoo handsome~
Hps are clunky, super hot, costs fortunes to run and the set up is crazy, an LED is hung up plugged in and done, if you have to take down lively, 😂
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
💯💯💯💯💯👌
1st
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.
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.
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. 😊
@@diezelvh4133 Just cause dispo weed sucks doesn't mean HPS is better. A lot of legacy dispos still run HPS.
You are incorrect. All the best growers use a mixed spectrum of HPS and LED
@@Generalumbongo i was just going to say this, cmh and hps still have their place in colder climates. I really have no dog in this fight and its a bit disturbing how fan boyish some of you are.
Shane aka migro has the best advice... and growmau5 who pioneered led lights here before anyone for the herbs... i know the topic well and educate people here 18 years 😅
samsung lm301b diode is what made it 700 watts to replace a hortilux 1000 hps.. i grow commercially so i know the topic years ago 😅
look at shanes old videos about thee old gen led that was half as good as the ones today
he was shilling theem like every other scammer
shane reemovs all the questions about th things he do.
so much bullshit
the other day he was showing people how to burn down their home while giving the plants toxic fumes (creating co2 with a candle light )
just to get a little co2 that would have to be vented out with the toxic fumes
You can get a good 600 W LED lighting system for under 400 bucks
630 de cmh is the best
It would be cool if you tested one
No, 315 solo.. also cmh by philips. I talk lights for 15 years here, before migro.. which is likely the guy at the start lol... yep of course ha.. double cmh is too close, i used them 2016 and it grows the same veg as a 8 bulb t5 which uses 110 more watts... for growth it does add uvb which helps resin (for the plants they were made for hemp etc) the first pioneer is growmau5, who proved samsung lm301b diodes beat hps... its all documented so thats undeniable
the best is led by scynceled, ragingkush2, with a single 315 philips cmh... i study this on a commercial level for 20 years.
We're fighting about 2 different things. Led packs on weight, sure. Hps gives sticky, quality results.
LEDs are crap
Laughably wrong... for years
"Frankly ridiculous"

Agreed, I know a premier grower that only uses hps. There's much more to it than just yield. It also makes a more diverse profile.
@@marcussmart3275 I know a lot of 'premium growers', they threw their hps bulbs away years ago, some build their own led matrixes, some use off the shelf. None have ever even thought of going back
