Bought a bestva 2000watt led grow light.

[Viceman666]

Cut that Kind to 5/8 the power it's using now & it may come close to the efficiency of a good fixture.
No, I wouldn't buy one when I was a new led user. Bought a Hudroponics Hut instead.
Put it up against a decent light & it got smashed.
My buddy bought one, it can all beat up w/ bad diodes. The comp. gave him a rash n a shit about it. Terrible warranty & service.
Do the new ones offer mostly wh/ w/ the option to enhance via controls w/ R's+B's?
If so, then dimming it down to 5/8 & selecting the right spectrum will do The job too. Just over a small area though.
Good luck.
Most of these guys are justvtryingvto help.
If your name is HoLightResearch, don't you think being more open minded will help w/ your research?

Ok fair already it makes more sense.. if you dim them 5/8.. but that means you loose 3/8 of power for probably not much more in efficiency which makes them even worst in terms of $/w

 

[HolyGhost23]

How do you arrive at that conclusion?

if it aint cree cobs or veros or citizien its garbage. or CMH or HPS.

Oh, they are terrible if comparing how much umol/j over an area, which is basically what efficiency is all about.
So, the $/J/w is not competitive nor delivering more light over an area per watt as HPS. So what's the point? Spectrum? Not if you compare results. Never mind the BS they may try to sell you on Burple being only what the plant needs. Sure, great supplementation to any white. But not a stand alone spectrum for flowering.

Please call then magenta from now on "What are you 3? Is that a color in your crayon box? Get some big boy crayons with magenta instead of burple."

I totally agree with you

Once enough people lost respect for the color magenta after being sold a promise that costed them allot more then they're light, the color became Burple.
You have to earn your respect as a spectrum & Magenta just hasn't.

re stock your shit and ill buy 2 driver kits off you. if you ship to Canada. ive been waiting for some citizen 1818 light engines for months. i dont want any of the drivers you have because there too soft

sure just email me with whatever drivers you want

as for the light engines they are built to order so if youre waiting for them to appear it isnt just gonna happen

clu048 engines go together quick

 

[CobKits]

Cut that Kind to 5/8 the power it's using now & it may come close to the efficiency of a good fixture.

when i had them i tested them at all level of power and output was linear with power input, which was unusual. in other words efficiency did not increase when current was lowered

Lets just stop the debate here on the "magenta" light.

It is full spectrum. 12 different wavelengths all individually tuneable.

think there has been enough proof in other thread to tell you otherwise..

The Kind is nothing like the cheap Chinese garbage. There is no proof in other threads. It does not exist.

If mono LEDs were not more efficient than a phosphor pumped LED then why would they exist?
You most efficient spectrum for absorption and action is deep red. It is very inefficient to get red out of phosphor driven by a blue LED.
The blue is more efficient because it does not lose photons in the phosphor.
Phosphor and monos are about equally efficient only in the amber wavelengths. Monos are more efficient in all other wavelengths.
It's not debatable, it's fact.

I think you are confusing top shelf colored LEDs with the cheap Chinese garbage sold on Amazon and eBay.

blue for veg and some red for flower.

Antiquated recipe. And you forgot seedlings, no red, blue and yellow.

So please provide me proof that playing with different spectrum will significantly change the quality/yield

Right. What world are you living in? You have to pay big bucks (hundreds of thousands minimum) for that information or do the research yourself.
I cannot talk about cannabis for legal reasons, but for example Driscolls spends millions on just strawberry flavor and aroma research.
Most research is not published. When a government agency (e.g. USDA) pays for the research then it is made public.

Do you think these guys leave their spectrum to chance?

if it aint cree...

Idiot. They use mostly Cree.

 

[GrowLightResearch]

spectrum & Magenta just hasn't.

Does no one read? Kind K5 is not blue and red. If you want white crank up the green.

You have to earn your respect as a spectrum & Magenta just hasn't.

Well if you use a Mars Hydro of course not. If you want top notch results you have to pay for it. It's pretty clear no one here wants to pay the price of admission they'd rather play with their child's play "burple" shit. Heliospectra has earned respect.

White LEDs are used becasue they are inexpensive. Not because it is great spectrum. Weed will grow well with nearly any spectrum.
I'm not putting down white. I have seen the photos of what you grow. You do very well.
I just find it annoying for guys to make poor assumptions about a product they obviously know nothing about.

I assume that those that have had bad experience with mono full spectrum lights did something wrong. Often these two words are a huge hint at what went wrong: mars and hydro.

You just nailed it. It would take 100's of thousand/millions of dollars to find the right spectrum if it exist - keep reading.. perfect spectrum may even vary between different strains and could vary within different pheno of the same strain as well..

Now lets just get our head out for a minute.. what someone would do with a kind led with adjustable spectrum when you dont know whats the best spectrum and will never know unless you spend 100's of thousand/millions of $$$ and time, time and more time.. which makes this a nice feature but also useless for most growers here. Most canabis commercial growers use hps not heliospectra - they do have different needs than home grower for liabilities reasons and insurance

Oh well was fun seeing you troll us all day long

Edit : Im not an expert but I looked at the datasheet of helio spectra and they use 5700k led + red diodes at different frequency (450nm, 660nm and 735nm), therefore playing with the spectrum is probably just a matter of playing with the intensity of those LED but not each led will have the same wavelength each has their own spectrum.. the same way ive seen people trying to play with the spectrum on remake of quantum boards or strips using some 2700k and some 4000k+ mix together to end up getting a different spectrum..

But at the end its anyone guess which spectrum is the best and this is why people trying different thing share they results on this forum so everyone can learn from it without spending millions of dollars.. this forum helps make all of us better growers

That is likely no longer true. What I am hearing from large scale growers is they have been moving away from HPS. Of course they are in competition and do not reveal what they are doing to their competitors. Heliospectra is making inroads in cannabis. Everybody that has one loves them. I even wrote a PHP app that uses the 9 channels of wavelengths as the bars on a graphic equalizer to play music to plants. Plays an MP3 with 20 millisecond response time.

I am not a big fan of Kind. I do not think they can be call horrible either. They are built very well and off high efficiency using top shelf components. They also have features that many grower do not need. Before someone calls a product horrible they should have solid evidence that what they are saying is true. @hybridway2 is the only one that backed what he said. I also have high regard for what he has to say. He know how to grow weed.

I would like to clarify I do not believe Blue and Red is the correct spectrum for cannabis. White is a safe spectrum as it covers all the bases. And it works very well.
Neither do I think white is the best. It is by far the most economical.

I took this picture a minute ago. This is my work in progress table. Notice white strips. The other stuff are custom tuneable 7 channel boards. Each channel can use any wavelength. The LEDs are on little PCBs that are screwed on to the main board. The intensity for each channel is programmable from 0 to 1023 where 1023 is 100%. The strips are for a personal project.

Fuck off, I do not troll. Everything I said I believe to be fact and if you cared enough you could confim waht I said on your own,

It's fucking rude to call someone a troll based on jack shit. Why did you find it necessary to be a fuckin' dick????????????
Goddamn sociopaths everywhere. I'm just a nice guy sharing 40+ years experience before I die.

That's life in the big city. Grow up.

Here's a public study that identifies what to look for if you have a GC Mass Spectrometer to analyze your weed.

 

[wietefras]

KIND led fixtures ARE horrible. When tested it had only 19% efficiency.

People with imaginary experience have only imaginary information to share.

:edit: Lol and then on the bottom of the page we get a KIND led commercial. "Gear of the year 2014". ROFL.

 

[SPLFreak808]

About half the efficiency of a 400w hps and half the output of a 400w hps lol, terrible imo.

*"[NEVER USED LEDS BEFORE]"*Bought it through Amazon, found a great deal on bestVA 2000 watt double chip led full spectrum grow light. Seen it on Amazon for cheap, and bought it on a whim. Figured if all else fails I can still use it for veg. My question is, I know you get what you paid for, and that's why I'm saving up for a "kind" k5 xl750. 850$!!!
But will this 2000 watt led be enough to start my girls with. My grow space is a tent, 5×5×7. Any tips or advice would be greatly appreciated. Thanks in advanced and keep growing them happy plants

Just curious, did you try the BestVa 2000? I bought one a couple months ago and am thinking I am going to like it from the results Im seeing....

 

[Aolelon]

Also dont trust those LED panels when they say they have UV spectrum. They are using a couple diodes that barely touch the 400-410 uva spectrum. That would be more in the blue spectrum if anything. I would hardly call that worth it. If you want added UV get a reptile t5 uva,uvb bulb. And cobs have enough light in the deep red and far red spectrum to cover it. No need to use IR
