Quantum Boards Grow

Damn bro you just follow led threads around talking shit. Don't you get bored of that? How bout you buy some leds and do a grow journal so you can prove how bad they are I would love to see a terrible grow your always talking about
18 oz harvest(500+ grams dried buds) from 400w of LEDs i know what i am talking about i been using LEDs for 4 years. I know your new to the forum but maybe you should look around before shit talking. These quantum boards are old tech, they are a PCB light without lenses. Don't expect much intensity from them without proper optics. Even with proper optics these lights are still old tech and won't have great intensity, they will need to be hung 12 inches or closer. I noticed you never posted a picture of a plant , do you grow buds? Bet you just here to talk shit .

1.2 GPW sounds less than most get with LED. id call that about the minimum a relatively meticulous new grower should expect.

saying lights need to be hung at a certain distance without doing at least a napkin calc on par from the light vs area is erroneous. these are literally no different from a cob putting out the same wattage. same or better efficiency, with better thermal management and light distribution

Whats wrong with higher efficiency"old tech" of course you need optics for penetration thanks for stating the obvious. My point was you don't need to talk shit on lights that work if used correctly

Your canopy management sucks and your light distribution needs work.

You could be getting .5gpw more than you are with just these changes.

I guess we'll see who's right about COB LED and these new boards.

After all, you've been wrong before...

Often.

How would he know? He doesn't use the ones he has worth a damn!

Never said i was perfect and i would agree, the area i need to improve the most is canopy training. But getting over a pound per plant in a 4x4 is a pretty decent haul. And i never said anything bad about COBs i like them, i said quantum boards are old tech that lack intensity, they are basically an all white led like an area 51 W100 or apache tech all white but without optics and smaller diodes.

Again, people are getting confused with penetration.
No matter how bright your light, it ain't going to go through any leaf matter and producing enough light for the leaf underneath. It's about light coming in at different angles which gives better penetration.
The more sources of light, the better the penetration of light into the canopy, so in theory, these are better than COBS. And these being DIY'able makes it very appealing.

That's not really true, depending on the spectrum some light can penetrate(green goes the furthest), and due to the law of the inverse square a multi diode light will be much less intense than a single point light with equal wattage(the lower the wattage per diode the faster the intensity fades from distance [ it is a linear chart like x^2 ]), what it boils down to is you will need to keep these lights really close to your plants and another under the top won't get shit for light.

These all use that PCB board glued to a heat sink concept not a new technology. Basically these are a step in the wrong direction, COB LEDs were a step in the right direction. We want more powerful diodes not multiple weak ones.

Gosh it's amazing how much you know about these old chips, that have only been on the market for less than a year!

So do you have a degree in engineering or physics that would allow you to substantiate your claims?

BWAHAHAHA!

New chips are being made every day, that doesnt mean they will work well for growing big weed plants, this is old technology with new chips in it, doesn't mean it's better than new technology with new chips in it. It's like if i take my area 51 light and upgrade it to the best mono diode crees on the market, it will be an upgrade, but will it be as good as cob lights? i think not.

These board type lights will always suffer from the same problems that the original blurple ones did, lack of intensity, they kill the ratings in a sphere but who grows weed in a sphere. I been trying to explain this to you LED users, biggest problem with LEDs is lack of coverage due to lack of intensity which makes you have to run the LEDs close, COBs kinda helped fix this cause they are much more powerful than a mono diode fixture.

Good luck getting that type of penetration with any light. Here's a shot at the Aussie sun here at the moment way brighter than my LED could ever get.
HID lights penetrate good because the initial value is higher so you can place them higher, a 1000w gavita run on 1150 watts should be no lower than 10 feet high. The sun where i live is super intense, i live at 6500+ ft altitude so i hear you on the bright intense sun.

Speak for yourself. I want more low power lights, not fewer strong ones.

My track record would support my assertions far better than yours... cuz you can't even back up your bullshit.

Look man, stop with the arrogant know it all act. we've all totally seen right thru it. You need to actually get an education instead of playing asshole on threads that have nothing to do with you.

You lie, you make shit up, you pull stupid shit out of your ass and you play with obsolete equipment and then try to extrapolate with no knowledge base.

No one here respects your opinion- they'd have made themselves known by now!

You really need to go back to basics. I'd start with trying to grow an even canopy, lol

Oh Gawd, look! Yet MORE bro science bullshit! But you KNOW cuz you saw it on a thread! lol

You're the LED village idiot.

How is that true when everyone has experienced better penetration with COBS? Which are only a small fraction of the power of HID?
Anyway, my last post about this and back to my gardening

Untrue, cobs are to be hung 12-18 inches from canopy, HID lights are to be hung 2-3 feet above. I think i am done trying to teach you guys, it's a lost cause you guys rather fight the truth than learn. Have a good night.
