HLG vs HGL Side By Side Take 2

[hybridway2]

That is one thing I gotta give her props on and something you definitely don't see many other "box" led fixture sellers doing -

https://www.hydrogrowparts.com[/QUOTE
Yup! Specifically designed to upgrade.

That's 15 watts per light fixture....correct? So, 60 watts going to cooling for 4 HGL fixtures compared to 0 watts going to cooling for the HLG Trinity?

@hybridway2 Yes, I agree....I don't think this contest is going to produce vastly different plant-growth results between the two fixtures....because the plants only care about photons they can use. And it doesn't matter what kind of light produces those photons. It can be anything from the highest technology lights to a bunch of incandescent bulbs in an aluminum foil lined closet -as long as there are enough photons and rest of the growing conditions are accounted for, of course.

I think the results are going to be close! I wouldn't base my pick on the results of the plant growth. I'd make my choice between these two lights based on almost every other factor -like the durability, electrical safety, ease-of use, simplicity, weight and lack of moving parts.

You wouldn't base ur pic of light to own?, based on the outcome of the grow?
N.O. but i think ur missing the point HGL is trying to prove.
We all know she's going to upgrade her fixtures & change the design in the near future. She made that clear admitting her tech or way of light dispersion is now played out.
The reason she's so cocky throwing a decade old design using Epis up against whatever she could find to be the baddest Ass, voted n all. Is because of the spectrum & science used to make it that has been ignored since bad burples blatantly beat us up.
Example: i remember being haggled on my Amare thread a few yrs ago by a guy whom asked me for links supporting evidence that "Amares'" enhanced white (they are not all the same & its noticeable when growing) spectrum is better then the plain white. After a few chuckles cuz i don't do links n computer stuff much, my response was: yeah, just look at any of the 1000's of Chlorophyll Peak Charts that have been available forever. He did not respond.
Its messed up because of the fact that shitty Burple lights using crappy components sold by shady fly by nighters caused such shit results people just totally disregarded all the previous scientific Data supporting specific Nanometers.
Now, with the slightest of common sense, seeing results ur satisfied with that r prob better then ur hps (sad part is many never even used the hps but think they can compare their leds) using inexpensive white DIY rigs. Why wouldn't that person think if white does so good & Burple used to & has data supporting it, then Obviously the White that is targeting Chloro Peaks in its SPD is better?
Yeah, its that Capt. Obvious shit they didn't get, ya know. Just Mooooing along, following the herd. This test here tho, scientific Cammi Data or not is not the same as comparing white to enhanced white. She prob sees it that way like i did then & i'm/we're the cows mooooing along. But if that was the case then you're really gonna tell me 12 yrs have gone by that youve been making loud claims & selling the Penetrators but one of the most knowledgeable forums available has no clue & nobody else has tried ur 10/15/75 ratio thats been made public a decade ago??? I just dont see how something so special slipped through the cracks like that?
Sure, u were banned & erased. But no one else saw the same study n decided to build led grow lights?
Why does Advanced, Plat, Mars, CLW, BlckDg, all use allot more then 10% blue?
And why is it that when Hortrilux ran 10% blue it was so desired to have more so they added more?
Terpins n Trichlomes
Now here we have HGL saying if its white phosphor at all as the base then its gonna be sub-par to her older models even.
Soooo, now we find out the truth.
I do hope everyone can agree now tho that properly enhanced white is better horticultural lighting then Wharehouse lighting.

6 watts per fan, total draw she claimed was 140 watts for your fixture total.

@hybridway2 If the light is enhanced especially for plant growth, then that's all good, too -as long as the plants which are grown under that spectrum have been allowed to reproduce under it for at least one generation. Most commercial seed stock that people can buy, have been grown under HID lighting, so, when you take those seeds and grow them under LED light, the genetically-imprinted expectations (for lack of a better term) of that seed will need time to adjust and re-tune itself to the LED. And the same goes for all the other growing conditions, too. Subsequent generations would be the only real way to tell.

I also think that chlorophyll peaks may be slightly off-goal when it comes to marijuana. I believe that things like terpenes and volatile esters could be variable under different spectrums regardless of how much chlorophyll a plant is producing. I have no science to link for this belief -(other than my first-hand witnessing of some of the stinkiest and tastiest weed I've ever smoked), that was grown under fluorescent shop lights -and grown under them for countless generations with little-to-no variance. Lot's of cool, white/blue light sitting low onto the tops of extremely manifolded plants....wow! It works!

It's my belief that a plant will adapt to its light source, if allowed. It just takes time, growing style/knowledge....and also selecting a good male to pollinate the females under those conditions, so that the seed will have that environmental-imprint.

I think this contest will prove to be very even between the two companies -as long as the photon energy is equal.

 

[whytewidow]

Yeah i think it was something like that. She actually was saying that keeping leds cooler helps them run more efficiently (which is true) so in the end that 15w was not being wasted.

But the hlg has no cooling and is more efficient than the LEDs with a fan keeping them cool. So it's actually double the waste of electric.

 

[crimsonecho]

But the hlg has no cooling and is more efficient than the LEDs with a fan keeping them cool. So it's actually double the waste of electric.

Now thats her claim. The relative efficiency of the fixture is not based on a comparison between it and the rivaling fixtures. Its a comparison between the same fixture with fans or without fans. And seeing leds can have serious output differences based on the temperature, its plausible but i understand your angle too.

Results of to much high intensity lighting via following recommendations.
View attachment 4331811 View attachment 4331812 See the purple/red vein? Thats an indication of a serious problem about to occur if i do not nurse her back immediately. FYI this happened from starting at 12" & moving up to 18" via instructions/rules/demands from HGL. If i do not follow all these "recomendations" then i am told i will have to return the lights after all my hard work. View attachment 4331813
IME this issue is a real PITA as its very hard to reverse. I usually use the MH DaylightBlue in weak intensity to cure this problem but do not have that luxury here.
So, i backed the lights up quite a bit for recovery. Wish HGL & Me luck pls. Ultimately I'm the only one who suffers if these plants Croak.

rec·om·men·da·tion

noun: recommendation; plural noun: recommendations

1. a suggestion or proposal as to the best course of action, especially one put forward by an authoritative body.
   "the committee put forward forty recommendations for change"
   synonyms: advice, counsel, guidance, direction, exhortation, enjoinder, advocacy;More
   suggestion, proposal, submission;
   rider
   "the government accepted the advisory group's recommendations"
   • the action of recommending something or someone.
     "he selected his staff by personal recommendation"

Funny thing about recomendation is that it does NOT always apply to every situation. Only the plants can truly recomend or Demand shat they want. Not a person 1000's of miles away whom simply does not grow my plants.

HLG on the other hand recommends 30-36" at any wattage that makes the plants happy. So Basically, Stephen recommends i do what's best for my plants.
Here it shows the beginnings of light stress that took place the 2 days i had the Trinity on full blast (525w). 8 hrs of 32" was enough for me to see i had to raise the fixture. Raising to 4' did not help so after 2 days i lowered the wattage & dropped it to 36". They should quickly heal up now & are already showing signs of improvement . View attachment 4331820 View attachment 4331821 Here you can see the purp vein started to take place but i backed off & they should get better now. View attachment 4331823
The Smaller plant used to show the leaves in these photos are the big Cola plant (HDF x ST) that i had high hopes for as being the competing plant if only one fits. Shame.

So guys I’m new and hate to butt in but are you guys saying that the intensity of the light will cause purple veins ...

Before they are ready, especially in coco with led, YES. They require or enjoy certain par levels at certain ages . Spectrum also plays a role in this hence the issue more so with led. Once adjusted & prepared they fair better but it is what it is. Gotta keep them happy. Strain dependent as well.
Unhappy for to long 7nder anylightsource will lead to damage.

 

[Ryante55]

The ONLY "problem" I've ever had with HLG is that, whenever I have been ready to order one of their panels, I find out there is a newer panel, with even more features I want, a few months away from release....so I wait for that one to come out and then when it does, the same thing happens over and over again! I know that when I finally commit to buying one in the future, it's going to bug me when the next model comes out a few months after that. Same thing with several other companies, too.

I'm curious as to how much of the actual power draw from the wall goes to powering the fans on that array of HGL fixtures.....? Also, it would be nice to know how much heat is generated by each setup. I realize your space isn't aligned for that in this test, but it IS a concern for tent growers or growers who have to deal with temperature issues. I would imagine that 16 fans running is generating some noise, as well. None of this has anything to do with this "white vs purple" spectrum comparison, but, as a potential customer, I'm making my own comparisons while observing this test, as well.

Heat generated is 3.41 btu per watt you can do the math on any fixture

 

[Axion42]

Are those the new 301h diodes on the trinity? You allowed to talk specs yet?

 

[Hempire828]

Looks like you fade ur plants like I do.
Seems to be purpling in the majority of the pics. No expert but maybe they want some N or P.

thanks bro.. man it has become challenging.. I’m In loco coco... more studying to come!!

When you have purple stems that are not due to genetics it is always a good idea to rule out magnesium deficiency.

Are you knew to led growing? Are you having issues?
Good news is you're in CoCo-LoCo right? FoxFarms product.
Thats not CoCo n doesn't even have enough in it to justify that name, which throws many new growers off.
Its soil with enough perlite n coco to dry within 2-3 days.
I ran it for a few yrs 60/40% Coco/CocoLoco. Shit is awesome. Just don't make the same mistake i did when switching nutes to experiment. Dont run a CoCo Base Nutrient & treat it like CoCo. Your run-off will explain why. My good results using that mix was when i used a nute line that the Bases could be used on any style or medium,water.
Growers in soil rarely have the led problems COCo growers have. Hydro is safer too.
Hey, im a few yrs in with led & just putting all this together now. Trail & Error &Error & Error & talking to others finally has got me feeling allot better.

Rule it out? Hu?
You mean something else caused the problem that lead to the mag deff.?

Not talking about your plant.
Mg def is a common cause of purple stems correct?
He is asking about purple stems and says he needs to study.
In general I am letting him know he should research Mg def and purple stems and make sure it is not his problem if I read his post correctly.
Could be I'm stoned and read it wrong.

^^^ what he said. i made the switch from soil moms to coco(great on budget and nute control). Then hid to led. Never looking back. Didn’t even wait for yield results from harvest. I would have to do atleast 3-4 cycles to have a definite answer. But what I do know. Electric bill lower, I can cover way more plants in veg and flower. My main grow style being sog on flood tables is perfect for how I run these boards. I have extra boards I haven’t setup yet and when my final veg room is finished I plan on throwing autos in there just to make up for my yield difference with my learning curve I’m going through. Also made the switch over to jacks hydro

Yeah, i know im stoned. Just smoked .6 off my party cup. Oh my!
Yeah, sounds missunderstood on our parts. Ha! We on the same page now.

 

[Hempire828]

I started with some blurples.. reading grow weed easy.. convinced myself I could make it with the galaxyhydro 300 x 2 did well.. now I have to 315w Vivosun.. plants growing like crazy.. however I did add soil.. after reading up , I mixed a batch of loco and ocean forest cut with perlite.. I go 6.2- 6.4 ph wise..I mainly use rainwater if I can..all organic OMRI label.. kelp and big bloom and feeding soil with Alaskan fish feet... eliminated grow big and tiger bloom..

Ok, that was a little funny

 

[Fake stoker]

Very interesting. Want to see a comparison between HLG and Mars SP light.
Both are affordable for normal growers. Want to see which is better.

Yes, i was also surprised. So i bought one SP250 without hesitation.
