The spectrum graphs indicate no gaps, put all the bands and luminescent coatings and there are gaps. I've said every way possible for you to work this out. Let's back to those graphs, the sun's spectrum has lots of tiny gaps if we look on a spectrograph, do your now saying LEDs have more...

Again the charts don't show band gaps, even when they improve leds how can they improve what looks to be an already perfect emmision of every wavelength under the sun! Don't bother I understand a lot of this goes over your heads, those charts were the same before improvements were made which...

It's one point GML made, even when others said he was wrong on results he simply argued them down and showed his useless data. RIU seems like that, I have the best plant, this led chart is fuller than this hps chart.

Those charts don't show band gaps just a continuous spectral emission which is not a full picture. Like make peaks join the dots and you get a similar problem describing a technical aspect of light. It's why leds use luminescent coatings but I have already explained.

Because led is limited to it's gap wavelengths and hps has more wavelengths. I did say hps wasn't balanced like an led and led generate more efficiency which is why they are the best light for growing.

Too late your original comment did just that, too bad you don't know the limitations of your luminescent coatings and what appears to be anything about band gaps but someone said there's an ignore button so maybe press it and you won't get in the situation of describing a hps light in the same...

Shit and there's me thinking you would type up the limitations of luminescent coatings, band gap diagrams on spectral emissions and give some real truths. How does white with 2% blue have fuller spectrum, please HPS has fuller spectrum in many areas not just there, apart from uv it kicks your...

LEDs omitted a lot of the spectrum, focused more on blue red and slimmer peaks. Don't know anything, what's the width of each band on a real light bar chart then? I'll wait since you like putting everyone down and think your the know it all.

Shouldn't you have seen this coming? If you have a special place for RIU why not say before this went nuclear in all that time? You could have kept him happy without the 10% it's bad business for you. Moving forward are we going to get more testing and better standards? The guy trashed...

Sodiums are a good mix of gasses, cmh even better when looking at line spectral emission chart. Much fuller but led has better balance. I'm not expecting you to know the ins and outs of light to this level of detail. It's why the sun has the best emerson effect being a ball of gas. Led...

I'm not comparing sodiums as better just how led manipulated data and made sodiums a lesser product. Sodiums would be better if they could spread that out more even, it has obvious flaws. I own leds so even I'm bias towards them.

Well he suggested it Im not a light company so I can say it without being Olympian.

By either manipulating spheres in house as he said or by choosing diodes that were giving certain spectrums which on a light chart gives higher light output. Sodium has a fuller spectrum than led it's not as balanced, it gives more colours or bars on a spectrum and LEDs are more hitting a few...

Companies manipulated sphere tests and spectrums to give best figures, companies selected the top bin and spectrums to manipulate tests, companies attacked any one or other companies that pointed this out or got different results on light tests. Looks like fraud was committed by most companies...

Wow Jesus, pretty cool.

I have no opinion it looks fantastic, just wanted to get your take but seems just natural height then.

Pulling up a seat, most interesting grow here. One question, why so tall?

There are enough bases in soils to neutralise any acids from water and nutrients, fertilizer is also a play of acids and bases. Let's face it you don't need to pH in soil unless your acid ppm is way of the chart crazy high and that's not going to be tap water is it. Hydro is more a question of...

2gram a watt is low for any light with good growers, the point is about the difference being an honest number not who is the best. Still seems to be a dispute and then gml comes over with how most led companies are shilling us.....

But most who caused dispute had led in one room sodium in another and the difference wasn't as advertised. Then I commented on a Mars as thread where they were saying sodium was monochromatic but my reply that led was closer to monochromatic than sodium. Then they add on ir and you get %5 for...
