Grandmaster Level - HLG Quantum Boards vs 1000w HPS side by side (youtube)

[lukio]

give GML a par meter and get that uniformity on point @Stephenj37826

his first grow with led and he encountered the usual teething problems...no biggie. he knows what went wrong and ive no doubt he'll correct it next grow. Not to mention his health, anyone see the vid of his scarring? fuck that. mad props for even growing while going through all that

There you go, smart move. Seriously that isn't a joke or being sarcastic either.

Leave the science to those who are qualified, the rest of the bunch are just critics.

Unless your room is the exact same as theirs it's really just a piece of study imo. Your room with the same light will run different then my room the same light. I could pull 1 gpw you could pull 1.7 gpw. I say run them both and see what preformed better in YOUR room.

Wow the ignorance is strong in this one.

You don't think that a proper research project comparing multiple light sources would not determine the maximum yields for area?

Dam 'gro bros' and their lack of understanding.

No I'm not saying it means nothing jack ass. I'm simply saying just because your researcher did 1.7 gpw don't mean you will to. Every room is different so unless you mimic the room that they are using it won't be the same. Some situations hps will be better some situations leds some situations it wont matter.

Researchers would hardly do something so foolish as to use gpw as a valid measurement. Grams per watt mean nothing, it is yield per area that matters.

Dam 'gro bros' and their lack of understanding normal science. They can't figure out the right way to properly calculate gpw even if it was useful.

Answer me this. Is your room going to perform the same as theirs? If they say they yield 3 pounds from a 5x5 does that mean you will produce just as much?

Answer me this, do you not see that it is a direct comparison of two different light sources?

Maths are hard.

Still same situation. Just because what they do means you will do the same? I don't need a study to show me what works for my situation. Maybe you should do some growing and test your own shit dummy. Don't depend on the next person to do what you can't.

Go on 'gro bro' tell us how you really feel.

I don't care about the room, learn to see how your plants communicate.
They speak sentences every day once your eyes and nose know what they say.
I'm too hot, I will be really thirsty in a while, I've had enough light today, you know, I really feel like I need to stretch with the light level so low, etc.... Shit, my roots, I'm choking!
My favorite one is, 'look how much I grew', at lights on time.

What went wrong, is GML was paying someone else to do his growing for him. End of story.

The notion that "something went wrong" is complete BS.....
The run may not have been "perfect" for either light source but GML crushed what most growers on this forum are capable of anyways.
So to me it is telling that all this "gpw" talk is nonsense and and there is a lot of building false hopes end expectations in this community.
As @Slinging PAR stated, if we are just talking light source against light source in a "equal" space, HPS crushed led by like 2 LB's.
No I am not hating led, I like led and just want to see truth to the discussion and honest observations without everybody getting their feelings hurt...

From the results, it looks more along the lines that it was this particular LED that failed to deliver.

Better LED vs HPS different story.

Having said that, better to give stephen the benefit of the doubt and have him run another test before being conclusive. That's fair.

g/W is the only useful metric in a test like this. Yield should be about the same on both sides. Because in a proper test you create equal environments on both sides as much as possible, which at the very least means the same average light intensity on both sides. Which should also give you about the same total yield (if done properly) on both sides.

Dam 'gro bros' and their lack of understanding normal science.

You're really the only "gro bro" here. Well you pretend to be one when we all know you have never grown a single plant. Everybody knows you have no clue whatsoever. Stop pretending and trolling.

I believe HLG is using about as top end diodes as available are they not?
Now spectrum is a totally different story. Not sold on single K temp phosphor led personally

Me neither. Haven't had good luck under all white led once except the Cloak.
I see people do it kindve. On here in bits in pieces. Big plants under all white LEDs are a tough win for me.

 

[ANC]

Well, I am doing alright.

Who knows. Maybe it was a bad batch. Maybe they got damaged in shipping or weren't set correctly. Many things could be the reason which is why if he can find some researchers close to him he can address them fairly quickly.

>>white light rocks as far as i can see [from a couple years experience]
...screwing around with nutes all the time doesn't help bro..
regardless hybrid you are a cool guy

as for the hps vs..qb.......isn't this second cycle grown good enough?

by" next round" you mean this current one that was getting finished huh..?

For sure. I haven't done much to help the situation by not nailing down a line by now. Had a whole yr w/ double the plant count to figure it out. By my going back to work I also couldn't put in the time I used to.
Idk why but I just have a tough time under the all white.
I've sunk my best veg plants into all white leds for flower & each time they took the worst beating. Sometimes Not making it to the end. I'm starting to think lower intensity when using all white along w/ nutrient adjustments.
IDK but have been side by siding in a rough grow environment w/ all plants getting the same treatment & notice myself having a harder time under 800umol+ white led.

 

[hybridway2]

I get that you want proof of which light actually is top dog. But you need to take into account plant health. I personally would not take this comparison very serious as the plants on the hps side were more dialed in compared to the led side

Prob because they Hps plants were allot easier to care for. I believe it's totally relevant & coinsides w/ my experience thus far.
