DIY with Quantum Boards

[Humple]

Agreed but I am just a simple man on a limited budget



Now I am lost, and not sure what you mean, because I did run the test in the same tent, same meter, clearly I have missed something here, or I am just fried and have missed something here

Think you missed that he was talking to CCCmints. Fry on, brother!

Not strange at all. Tent reflectivity can vary considerably. Even a quality PAR meter like yours can vary +/- 5% easy between meters. The true test is an independent PPF reading from a sphere. That withstanding, same tent, same meter would have been a much better comparison test. That's all I'm saying.

The problem with that is, the value doesn't take into account how well the light spreads over a given space.

Yeah, and the other difference is that I actually compared an HLG to an HID, where is your direct comparison?



Clearly, you missed the bit about the test being relative, as in I compared the HLG directly against HID, what about you?16 points is more than enough to see how the light is spreading, I find it seriously funny, that there you are, over there sitting on your high horse when your methodology is flawed.

But best of all, you killed it with your uniformity blag

At this point, I realize you are one of those shit talkers who is always right even when are wrong, and instead of just admitting it, you come up with some next level BS in order to keep your ego intact.

On that note, I can see you really do not have a clue or anything useful to offer the community, so I am going to jog on, and leave you and your funny graphs to it

.

Your comparison is worthless. Post a picture of your test, I'll post mine, and then we can talk about why there is an important difference in having 16 points vs 49 points. I tested 1000w HPS properly, you did not. My data should be fine for HLG since they've provided it. Unless you're saying your quantum boards are performing better than they're advertised, then I'll assume their data is accurate.

What is a "uniformity blag"

What is BS? I know it probably isn't good news for you, but none of this is BS. Those 'funny graphs' are actual representations of what these products do. I see this evoked an emotional response, and I understand that since you've spent your money already.

You should just be happy there's more to consider in terms of optimal replacements for 1000w HPS. Surely you can't think quantum boards are some type of revolutionary product that can't be topped.

I'm still waiting for one of you guys to use HLG's provided data to make a graph on your own so you can see that I didn't just type random numbers into a graph generator.

Just look at the sphere #s (umol/j system level) and actual wattage draw from the wall ; you'll have the answer. Remember though, that one suffers from faster depreciation & reflector losses=especially when dirty and oxidized.

Slow your roll there, hoss. You come in telling people that have replaced HPS with QBs (and seen the results) that they're swallowing bullshit, because of your test. Lots of other people have tested these lights, and plenty of them disagree with you. One nameless dude on a forum shouldn't expect to garner the consideration that you apparently feel is due. While I agree with your statement on uniformity, I also know that there are real-life examples of the 550 outperforming SE HPS. Now you can say that those HPS must have been cheap, shitty bulbs, or that those people just didn't know how to use HPS, but again - your word isn't gospel. Congrats on your COB fixture, but you need to chill with the hostility, arrogance, and insults.

I’ll chime in on this. While I have never ran a 1000w hid or a 550 I have run 400w hps and 250w of hid and now own a QB 260 kit some 120s and some 96s. I will say this, I’m not going back to hid unless I need a heater and then I just use a heater. My 260 kit set at 180w blew away 250w of hid and did better then my 400w hps. You don’t use quantum boards the same way at the same height as hid. They really helped me with my space and height restrictions. I was able to try new methods of growing and not have to worry about rotating plants. Not to mention less heat and less ac and also running my grow warmer meaning even less ac. I like what they do I had to change my way of growing but in the end it’s better for me. I’m now a qb lifer even tho I gave up growing cannabis but having the quantum’s make me want to still at least grow vegetables and anything else that won’t get me arrested just for the fun on growing with them. Never wanted to do that with hid.

I meant a 4-foot x 4-foot (120cm x 120cm) tent

Ok cool just checking it's annoying how many tent companies oversize their tents

An HLG-550 is just 4 quantum boards. I think my point can be easily surmised…Are HLG-550s not quantum boards? Semantics…

If that's true, then the only difference between your light and the PLC-6 is semantics. You are just intentionally avoiding the obvious point that a custom light made of 4 or more quantum boards(or of F series strips for that matter) would have done the same job for a similar amount of money using less watts than your custom cob build.

Its not an obvious point. Quantum board's light uniformity is trash, especially in comparison to my fixture. Go ahead and plop HLG's data into a graph generator and see for yourself. If it makes you feel better to believe my data is fake, that's fine with me. But if you assume its real, and compare it to your HLG-550 graph, you'll see the obvious difference.

To be fair, you're avoiding frigginwizard's main point entirely - that you are comparing an "off the shelf" light to your custom designed COB setup. *Obviously* yours is going to be better - just like it would be better than a PLC-6. I agree that the uniformity of the HLG-550 is not very good - but that's not a flaw of Quantum Boards in general - its a flaw of the HLG-550's layout. If you were to take 4 QB-288 boards, put them on separate heatsinks and put them in the corners of a 36-40 inch square frame so each board is centered in a quadrant (of a 4x4 tent), the uniformity issue is greatly improved.

I will concede to that point. Its not fair to speak as if quantum boards in general are the same as the HLG-550. More boards in a better configuration should provide great results. I'd like to see how a 6 quantum board design performs. From my tests, I've concluded that the LED:HPS ratio is optimal at 750:1000, so 6 quantum boards would be interesting. I might look into putting one together and post the data here for everyone.

I look forward to seeing your results.

So what was your last yield on a 1000 watt hps?

 

[CCCmints]

So what was your last yield on a 1000 watt hps?

about a pound

 

[standupRIU]

Hi currently using a 260W QB kit in a 2x4 tent with 2 plants in vege
Currently at 190W and 18-24" away from top of both plants, was abit much @ 250W. Reading 22k lux at 24" and 32k lux @ 18" from my phone
Should I be able to lower the watts much further?

 

[WeedSexWeightsShakes]

about a pound

So with a ballast that pulls like 1100 watts, yeah?
Just wondering cause my last grow I had around 1100 watts of qbs.

 

[WeedSexWeightsShakes]

I get a pound from a 600w hps.

I’d hope so.
Pound from 1000 watts sounds pretty bad.

 

[Yodaweed]

I’d hope so.
Pound from 1000 watts sounds pretty bad.

meh, still decent weight, pretty sure it should cover his growing expenses, even with prices dropping so low

 

[ANC]

From my tests, I've concluded that the LED:HPS ratio is optimal at 750:1000

That is correct, as that is basically the difference in photon output.

This run I will keep simple, strips spread evenly over tray delivering the light evenly and from multiple angles.
In a later run, I will move the strips together in a single, high lumens bar. Which would need to be hung higher and will have a deeper optimum light level zone.

For latest gen stuff the tables should be something like
300W - 320Wover 4x2 or 3x3
450W to replace a 600W in 4x4
and 750 for a 1kW HID in 4x6 or 5x5

I don't care what HLG says, 550 is not enough for a 1kW replacement.
Each of the boards is a 288 diode board, just like a Samsung type F.

Now I use 3 of those over 4x2, they use four 288 diode boards on a 5x5.
Maybe I'm missing the finer details on something.

No, the true test is what you grow with what you've got. Isn't that the reason we've gone to Qb boards? People can spout numbers all day long, plants could care less! QBs must be doing something right because more than one person here has spanked the production output of whatever HPS you want to name. When I see buds at the base of my plant LOOK like buds non popcorn, and are hard and stinky, THAT tells me the value of my light.
I also have COB lighting, no sense replacing them with QBs, they work and work well also. But 2 tents and two cabinets all run QB lights. QB style lights are also cheaper to build than multi-cob lights driven at low power and weigh much less.

And I laugh every time someone brings up HPS, its dead technology. NO? Then why has Gavita bailed on HPS to go LED?

no, it is, you're just intentionally playing stupid because you know I'm right.

or more boards, it isnt like his custom COB rig is only 6 COBS like the PLC-6. Hes just pretending not to get my point, because then he has to admit that maybe his new light isn't quite the modern marvel he thinks it is, but is in fact a minor step backwards in efficiency.
