Black dog led vs kind led

not all blurples are horrible- most use at least some white now and the targeted spectrums really pack a punch. if i had to take 1.75 umol/j of white light vs targeted reds (assuming rest of spectra is somewhat full) if probably take the targeted spectra

heres an HQ one not on your list:

California Lightworks Solarsystem 275 = 1.75µmols/j @ $489.00 MSRP
Watts = 200W
Good efficiency for monos and one of the better blurple spectrums, high quality build with excellent resistance to water/moisture and has programmable timer and 3 spectral bands. available in larger 400 and 800W units at similar efficiency and cost per watt

also id disagree with Gavita spectrum being "below average"

by industry standards it is the very definition of average with CMH and white phosphor LED being "above average"

Aww, here in lies "the rub" I use a 10 k finishing bulb in 1 of my gavitas. the bulb also claims to have UV.

White LED spectrum is below average, it's too narrow of a spectrum to be considered on the same level with CMH spectrum without any UV and IR it's just not that desirable.

And those targeted spectrum lights you are talking about cause deficiencies because they push metabolic rate the wrong way.

There's a whole thread dedicated to blurples causing deficiency, just look it up. I'm not making anything up.

Here i found it for you

Yeah that you can get deficiencies based on parameters of your grow is the only thing in that whole post that makes any sense :roll:.

Yet your claim that this is caused by the "metabolic rate being pushed the wrong way" is beyond ridiculous. How do you even come up with nonsense like that? It sounds like something from one of those Star Trek bullshit sentence generators. As is the rest of that post about "spectrum quality".

You will see different uptake based on a lot of parameters. So what? That doesn't mean it's "bad". It's just something to take notice of and correct for. In this case it's obviously not the color of the light which is causing the problem, it's the lack of radiated heat (ie less wasted electricity with leds). Which is easily compensated for by dosing the calcium a bit higher. Big deal.

Most indoor nutrients will be catered to HPS light and the heat they radiate onto the plants. So either add some calcium or use nutrients with more calcium in it as standard. I switched to Yara Kristalon powdered nutrients and haven't had to add any calcium or magnesium since.

What what? I make my own nutrients and compost, never have a problem unless i run my plants under shitty blurples than i get cal/mg problems, pretty sure it's the lack of spectrum that makes them do this as many others have said. I think you just looking to argue and troll like 99.9% of users of this forum.


Even my outdoor plants never have issues and it's really harsh out here in colorado. The sun is super intense during the height of the day and it's very arid and windy still no issues.

So .... you ad some calcium or use nutes with higher dose of calcium. As I said before .... big deal

Ehm, looks more like that applies to you, but I do tend to react when I read bullshit. I see myself more as Bullshit Man who corrects bullshit wherever he sees it:

UV/IR are overrated wavelengths.
Just look at the Mccree Curve.
Then look at the countless examples of dank buds being grown entirely without UV/IR.
My buds turn out just as good with or without.

I had a Hortilux Rep tell me that THC production in resin glands is controlled by UV-B receptors.
I called bullshit and his response was "some scientific studies just proved it so... I'll send you over the reports." Still waiting on those...

How are these inferior white phosphor LED spectrums growing dank buds???

for indoor farming UV are usefull only the 2/3 last weeks... before or from start to the end = skinny leaves and buds... it's only my own experience

I bought a Phytomax 400 from Black Dog LED and completed one grow with it. Here's what I can say:
Blurple lights (which includes black dog and kind) are outdated by the newer COB fixtures. Black dogs are some of the highest priced blurple lights on the market, but comes with good build quality, a great warranty, and is plug and play. Black dog is certainly superior to Kind LEDs though in build quality and performance, however, I don't recommend anyone buys blurple lights in 2017+; it is no longer necessary.

Up until recently, most of the COB fixtures were DIY. They would be shipped in pieces and have to be assembled. I bought a black dog to avoid having to do any DIY. I really liked having the reliability of the black dog combined with the plug and play ease of use.

Nowadays, a few companies make plug and play COB fixtures (such as pacific light concepts). If I could do it over, I would have purchased one of those fixtures as they will give you the best gram per watt performance, far superior to any quality of blurple.

Keep in mind, the black dog did pay for itself ($1200) in the first grow with one plant. I'll be using it for once final grow and then replacing it with a COB fixture, reserving the black dog for only vegging.

Its not the Blurple, its the diodes!

How many times is this going to be repeated Ad Nauseum. Wisen up, these diodes are pushing 15 years old in production life. Full spectrum diodes from the same, would also suck balls, compared to todays Bins.

I prefer Plue anways......:peace:

Agreed. By now there are super efficient royal blue and photo red diodes on the market too. I guess they could even beat a COB on overall efficiency?

It's a lot of work creating a light from those smd leds yourself though, but then I'm surprised no one is really trying the new burple COBs out. I would assume they are more efficient than the warm white ones most of us now use. If you follow McCree's chart at least, purple should perform somewhat better. I saw some talk about these when they came out, but haven't seen any actual builds with them.

I remember when Stardust was proposing different versions of how he would "re-color" some of the cob options, but is it necessary? I find the wave boards interesting from PhotonFantom....and I personally still want some IR to finagle with.....:peace:
