Light Quantity vs Light Quality Evidence ... Just for 4 u gg lol!

Your comment here is a case in point with regards to spectrum see below:

Look at the lack of Blue/Green/Far Red, and the ratio of Red/Blue it is way too high and the ratio of Blue/FR/Red is way too low for vegging and if someone was to veg under such a spectrum they are always going to end up with stunted plants... The tallness probably comes from shade avoidance response in the plant hence it elongates

This spectrum is clearly lacking in Blue and Far Red the ratios are out of whack, that is what I see as the problem.

Funny, everything I ran under such a spectrum grew like mad, whether in veg or not. Mine were 3000K but that's not much different.

Since I started using the Cloak they've since switched to 28k as I recommended for flower. They use 6k for veg & it does excellent.

The cri's not changing throughout the day, the K-temp is.

Ok then how well does a Red render under 8,000k - 12,000k blue sky surely it will render much better under 5000k?

This scenario makes much more sense, all I am saying is if you chucked more Blue and FR in there it would be even better.

Funny, everything I ran under such a spectrum grew like mad, whether in veg or not. Mine were 3000K but that's not much different.

You'd be surprised how much of a difference 200k can make, I see 2800 as a near end of flower spectrum.

Not sure I understand your question?
5k is your average daylight temp.
Mind you, they're not like wh/ led temps. Much fuller.

CRI is a theoretical scale, the theory being that sunlight in the middle of the day gives a CRI of 100 but this metric is subjective if you think about it, because does the midday sun look the same everywhere around the world?

Also you can have 2 sources of exact same CCT with different CRI's.

CRI is just a theoretical metric of how close each colour renders to a theoretically perfect source, e.g the sun at midday, not sunset, nor sunrise which would produce different CCT and hence not all colours will render the same as they would of the theoretical perfect sunlight at midday = Different CRI.

a perferct source?........how many times are you gonna call people names when they correct you?

If a light source displays these 14 colors perfectly the corresponding CRI would equal 100. If the light source did not display any color correctly its CRI would be 0 (zero). This is the R(a) standard for those who want to dig further, past hyberbole. The new standard CRI r96 has not been utilized yet......

The Color Rendering Index (CRI) is a rating system that measures the accuracy of how well a light source makes colors of an object look.

R9 or strong red is one of 14 test colors used to calculate a color rendering index. The higher the R9 number, the more accurate and vivid the illumination (perceived color of the object).

fyi cri is based on Visible light, not the sun, which contains HUGE amounts of IR.....derp.

 

[Abiqua]

Not trying to be rude but that thread is not impressive(tall and spindly plants with weak stems that look like they wanted more light), you could have vegged stouter plants with a way cheaper light and they would yield way more and been much healthier.

That suncloak is more of a novelty item than a real growing tool.

and if Hybridway or anyone else wants to put in here.....lets get the bins on the Cloak. Hybrid you have one, and have NEVER said what the specific bin is, just that they are "top".
and I can't get an email back from the company, politiely asking what the bin is on these lights....going on 5 months....all of the cheaper well known lights, don't advertise their diodes on purpose.....are we on the verge of adding the suncloak to that mix???

In this day and age, NO specs, No selects.....But maybe there is a glimmer out there, Randomblame?

Lets put up a bin code and judge them for their real worth....please....

Haha well well if it isn't my favourite troll come to do what he does best LOL

You have got a thing about correcting people haven't you?... unfortunately for you, I have yet to see the evidence where you have corrected anyone ROFL!

Another thing seems you have trouble reading and understanding context don't you, here let me see if I can give your brain a jolt.

You know these R thingy's above do they have a corresponding value 100 being perfect (except this isn't necessary so I mean what about HSV) or did that part slip your radar?

Speaking of slipping your radar, are you trying to tell me these artificial indices called CRI and CQS for that matter do not have Solar Sunny roots... If not then please explain to everyone, what the people who developed CRI used as a reference point?

Look forward to your replies

It's comments like this that make me feel like this

1) Please point out where I mentioned IR & CRI in the same sentence?

2) Does the sun contain visible light LOL?

3) Does incandescent lighting contain large amounts of IR, yet how come that too scores a perfect 100 why is that?

4) You know this idea of the visible spectrum and wavelengths, when were they discovered?... And by whom?.... And what was he studying?

5) Back on point is CRI a good metric to use with regards to horticultural lighting?

Deeeerrrrrp

Ps seem to remember you getting run off another thread for doing what you do best... aka Trolling lol!

I just don't have energy to respond....I think the comment was that I couldn't calculate someingthing for m^2.....but it is literally in my sig, the calc, so I just keep keeping on....No trolling.


Tell us newbies who don't know better how CRI is something about the sun at noon? Then I will quantify some of your remarks if you want....lets start there.....hmmm?

The other stuff is a straw man. Again, not surprising. I just hate the spread of terrible anecdotal evidence

 

[Johnnycannaseed1]

Abiqua your failure to answer my questions proves my point and the fact you cannot keep it on point, instead, you are using lame "Troll" tactics of try and attack the poster rather than the content.

When you are ready to answer the questions feel free to let me know... Ahh yes that's right you do not have the energy ROFL, yet miraculously you have got the energy to post nothing of substance funny that LOL.

Nice one and nice swerve, your dodge and unwillingness to engage in Q&A calls you out for what you are TROLL

Nuff said I'm out Peeeaaace

Im ready to answer the questions!

I just don't find it relevant, if you concede to making up your interpretation of CRI, how can I answer questions about made up scenarios?

Honestly....and again please direct any and all attacks to the subject matter, anything else is just trending towards the bottom of the pyramid, aim upwards:

@Heil Tweetler my gripe with your style is that you use the wrong part of this pyramid. I have a feeling that we might have a more meaningful discussion of you used the top more than the bottom.

The central point here appears to rely on the belief that your "gripes" and "feelings", what you consider "meaningful", concern me. They don't. I regard your opinions, interpretations, judgments not at all.

A lacuna in the "pyramid": syntax and grammar errors reveal a thoughtless approach which fatally detracts from any imagined conquest or basic ascension of this rhetorical summit.
