Buds quality LEDs VS HPS ?

Recommended Posts

Hello all grower around the world big up to Opengrow.

I just want know the buds quality under cob LEDs VS HPS ?

I can read a member say than LEDs buds is not very good,perlaps it have an other problem ?

If cob led user can say what's they think about it?

It's possible to found analysis off LEDs buds ?

Thanks before for your help friendly Olsqueak

Don't know about white LEDs. I quit buying green light 7 years ago.

But Leds that hit the absorption peaks do a wonderful job.

They rival tropical sunlight.

With half the running cost of HPS.

 

Posted pictures but was told .JPG is not allowed. WTF!

Check my media for LED bud porn.

I am using Platinum LEDs, which don't produce the white light. But they produce a spectrum of light designed to match sunlight. I have never grown with anything but this. I am very pleased with the yield and quality.

LED's are better, absolutely, no question. In fact, lots of info out there that suggests a GOOD LED increases THC content by 3-5% over an HPS.

 

I've used both, and will never go back to HPS, just a lot of wasted horsepower. My plants finish faster, growth is more compact, buds are MUCH frostier, and my electric bill is cut in half.

 

Today's LEDs have literally hundreds of excellent options and configurations. I use a Platinum 450 and 600, both are fricking awesome.

Okay first and foremost it's the environment.

 

But before I go into a big old thing HPS is still King for commercial seconded and coming in fast is the ceramic metal halide lamps. CMH.

 

Not all LEDs are the same so I am only going to speak about full spectrum LED.

 

Cost-wise I would recommend to CMH lamp as your temperatures are going to be relatively similar to an LED lamp regarding the wattage that you are using.

 

Since it's about the environment it is generally easier to cool an area with LEDs and/or CMH lights compared to HPS.

 

Quality-wise I like to see CMH lamp and the high-end LED lamp however we are talking a minor difference and yield is not as great compared with the HPS. However for home Growers this is a small difference.

 

I have seen HPS and those lamps run side-by-side in HPS is the winner if you're able to manage your environment. However you should factor in the cost of managing the environment when using HPS.

 

Your environment is more important then the light and nutrition your environment is what enables the capabilities of your light and plant nutrition.

 

I personally preferred LEDs in the veg room

 

CMH and HPS side by side it's the best of both worlds.

 

NAW did a test grow with cob LEDs which they no longer use in flowering as I understand.

 

I am not saying LEDs do not produce but I am saying it may not be the best option for the money spent and with light deterioration overtime it is simply not the Wonder light that some has believed it to be. In addition LEDs footprint in penetration generally not an equal.

 

Due to light deterioration over time is one of the reasons I prefer CMH lights as the Bulb has a longer longevity than HPS and cost a similar to an LED light. In the spectrum's our ideal.

 

Way too much information on light

Sorry Papalag I think you caught me in a edit. I'm on the phone right now and not with my normal stuff.

 

I'm not taking away from what LEDs can do I'm just speaking from a bigger picture.

No question hempy it is all about the environment but once you’re dialed in I feel leds do out preform hps

 

I’ll never go back

I say, if it works ..don't fix it..

I use MH for veg and also use a blue MH for the last 10 days or so to increase the trics...

 

friend of mine told me a few years ago and I can see the difference..

 

Hempy knows his shit..

Thanks, Hempy, for the environmental reminder. I blew probably six months of grow when I changed to LED due to environment nmrntal factors. Looking back, most issues were not enough cal mag or phosphorus, couldn't figure it out. The LED s really drive a plant hard, they are so efficient. I switched in winter, too, and even had to use a space heater, to keep temps up.

 

Regarding the original question, LEDs are known to increase THC 3-4%, primarily because of uva uvb spectrums. My experience certainly backs that up.

 

All in all, I like the ease of LEDs and the heat/environmental problems they eliminate.

Honestly, all that aside, just make sure to get some reptisun 10.0 bulbs for UV and your quality will go up regardless of HPS vs LED. Neither LEDs nor HPS will produce any appreciable amounts of UV

 

I've always been biased against HIDs, even when they were the only name in the hat. It's great in a commercial scale where overlap keeps things consistent, but a single HID is so fricken variable without a perfect hood, it's a bitch to try and get a whole tent lit evenly. Indicans got the right idea getting rid of the hood altogether, as it gets everyone the same distance from the bulb.

I had to stop running vertical bulbs as the occasional glimpse of a bulb over the rim of your sunglasses literally burns holes in your retina. No exaggeration.

 

There are LEDs right now putting out 200 lumens / watt tho, with crazy longevity. The spread can be compacted and extended to fit the space, and dimming is standard.

 

Really tho, the deciding factor for me is price, and right now the price isn't so different anymore.

Using high end LEDs in a DIY can get you >400w for $500, and life expectancy matches if not exceeds the best DE HPS money can buy.

 

Hempyfan is right, in that HPS is still king of the hill, but LEDs are not all the same scam sales that they were five years ago. Just gotta do your research into how much light you actually get for your money.

 

So now that you're thinking, "wtf does that have to do with bud quality?"

Uneven light in your tent from an HID can affect quality, as will a crappy spectrum. If you get a shitty HPS bulb you'll get big buds but no trichomes.

If you get a crappy spectrum LED like those 3band, 7band blurple lights, you're again going to get lower than perfect quality.

The tests we did with LED were all very disappointing.. product and yield look great, but the leds change the mental effect of the endproduct, in a very negative/undesirable way.

I have literally trashed entire jars full of great looking weed, because it wasnt worth smoking compared to hps grown weed.

 

The last of the fixtures I made is at LBH's place atm, he came up with a couple of ideas on modifications which should make the led-weed be at least equal or better, but until that project is succesfull no led-weed for us.. first results on those test will probably be in sometime around end of february.

Hello,HPS is very hot and air become Dry,not good for grow period.

When I use HPS I have some problems when days coming more hot Outdoor.I think with Leds COB Cree cxb3590 3500K I think I can keep a good temp in my box and have better results than HPS.

For the quality I can say when I have my first smoke test.

I think HPS buds and leds buds can be good if the plants is well finish.

I had issues with heat

Hps & mh are way too hot

In my old place heat wasn’t an issue but that change with the move

 

It did take me some time to dial in on the new environment but once I figured it out it gets better each grow

Peace

What leds did you use scirocco?

Change in mental effect should be consequence of different cannabinoid and terpene production.

I believe massive/regular selections under hps can make plants unfit for other lights, including sunshine.

 

Cheers

We at NAW believe the same, and we tested a lot already....medical value on selected HPS strains is zero under led.

We tried going the cree cxb way, with a very diverse collection of genetics, nutes, temperatures, lightpressures and so on.

Testresults were great, or even incredible... until you smoke the product.

The first few times with really fresh product you are impressed, but after a week or so you find theres something missing, and the more you smoke the more the difference shows.

 

We suspect theres something missing from the lightspectrum, in the new testruns we will add some new stuff to the fixtures to see if we can improve the product without losing too much yield.

(That was after all the entire reason of going led.. improve yield, cut powerusage and heatemmissions, and reduce risk of fire and chance of policedetection WITHOUT LOSING MEDICAL VALUE)

 

I'm still convinced that yields over 2gpw are pretty easy to accomplish, in normal 2 month grows.

If/when we get the product to not loose all its medical power I will do a new large-scale grow to see by how much we can beat 2gpw.

Interesting,

i only grow outdoors and indoors under leds(cxb3590), never under hid lamps.

I find my indoor buds much better than outdoors, better overall in all ways.

Only thing i believe outdoor buds have a bit more all around terpene production, indoor have more pronounced some terpenes, some less. Maybe it's same with cannabinoids, i think leds may produce less cbd. All in all the indoor bud may lack something but I like it a lot.

 

Cheers

A debate that I believe will never end. Mostly because it is personal preference. Just like everyone prefers a different strain. Just like some prefer organic soil over hydro grown weed. Both claim the benefits of their method out ways the benefits of the others method.

 

The only solution? Grow outdoors, in octopots, supplemented MH, HPS, and every spectrum of LED you can get your hands on. Lol

With all due respect, it's simply not true LEDs don't offer UVA/UVB spectrums. The good ones are designed with UV diodes in the array, the designers know this, and are competing to sell equipment. The natural affinity for HPS IS fading In commercial grows.

 

Being said, UV coverage rocks. I began using Eye Hortilux Power Veg with HPS specifically for their UV spectrum, with noticeable results.

 

I've divested myself from the us vs them arguements of HPS vs LED. Both work great, if environment is properly managed. My experience and research has led me to prefer the new LEDs in my personal grow space.

I agree with you Dieseldog381, it is no competition but i guess some growers feel obliged for some kind of misplaced reason to choose sides. But who are they really voting for huh?

Lighting is a tool and understanding each light as a tool will help better place to correctly for each type of situation

 

It should not be an emotional thing Nori pissing contest

 

However when using a tool incorrectly or if there is perhaps a better tool to use in a certain situation it is merited to explain that.

Well said, as always! Boy, I so recall the pissing matches of even five years ago over led vs HPS. BUT, consider what's happened in that time!!! Pots become legal in what, 4-5 states recreationally, and it's not a kids game anymore for hobby growers, it's a mean, aggressive, "I'm going to get mine" entrepreneurs game amounting to billions. Money is the mother of invention, and there is enormous capital chasing the cannabis market. Business sense demands reducing production costs, and the largest recurring cost is POWER!

 

The issue driving lighting innovation is power consumption! I'm in Colorado, a lot, and communities are having power grids taxed to the max from 5000 plant HPS grow ups, and 50 grand per month power bills, which can't continue. The innovations in lighting technology have been rapid, necessary, and impressive. All environmental control expenses decrease when heats no longer a factor, too.

 

Why, in another year, they'll have 60 watt incandescent bulbs that equal 1000 HPS setups! (Ok, that might be my Holy Princess talking there, lol).

 

Happy Thanksgiving to everyone!

I'm considering buying a few 300W LEDs to replace my HPS/MH. I like the possibility of controlling for less heat and less energy consumption. I remember when I thought LEDs would never compete, but it looks like the time has come to give them a shot.

Why? Interesting points, but what mental aspects are you speaking of? I've grown Sannies Jack under both, same with Apollo 11, several times, and found the led bud more flavorful, compact, and noticeably frostier. The HID buds were very similar, taller and looser, but I didn't notice a difference in the high, except a bit stronger with the led buds, perhaps.

 

With Jack as my benchmark, I actually prefer the LED bud to HID, all things being equal otherwise.
