yer i agree

but i think we have a problem how we talk about "blue" light in an led reference frame, 99 times out of 100 we are talking about a very narrow but quite intense band of blue right at 450nm. but all the surrounding "blue"nm are barely represented, massive gap at around 470,480,490nm and very little bellow 450nm you get a touch of 440 then it drops of a cliff, forget about anything around 400nm and bellow.

these missing blue nm are present in other grow lights in varying quantitys - cmh, metal hialide, t5 flourescents the sun ect...but none in standard led spectrums...we are missing a trick.

most white led diodes are based on the 450nm pump because its the most efficiant way of producing light... but im not sure its the best way for:leaf:

And now we have the Samsung mints at 435. I’m thinking it will help round out the blue some in lower doses.

Agreed. By saying 450nm is blue and 660 is red and focusing on them primarily is one if the main reasons today's grow lights do not perform nearly to their potential. I've broadened my spd, focused on filling the gaps and reducing overabundances. Now my plants are healthier, yeild more and are of much higher quality. Face it growers, none of the popular light companies are providing you with spectral content that is specifically tested for horticulture. Either find and use the one that does or Attempt to diy using the less then accurate Information they want you to believe. I feel terribly sorry for everyone using these seriously lacking spectrums with absolutely no guidance on how, when or why. Ive sbs'd anything that they call efficient and despite the efficiency differences my lights destroy these of higher umol/j. Why? Spectrum and delivery, that's it. Very simple stuff and completely common sense but only If youre willing to forget n let go all the false Information spouted by Bruce, Shane and these fake manufacturers of grow lights.

I'm thinking?
The sun with its huge wide spectrum of colours doesn't equate to bigger/better buds.

No it does not, especially in an artificial source. The burple fiasco wasn't entirely BS & either is the white. Both making valid points. Now if manufacturers would use common sense and spend at least one grow on research then maybe growers wouldn't have to depend on the false Information spouted. I use a spds that use the correct monos with only so much white. That's why patients buy my material over all other options.

The company I use has done this and I'm actually glad others have not. That's why patients buy my material over all other options.

I'm always open to learning, why don't you show me why it is people come to you?
A picture says a lot.

The only way to see is direct side by side pictures and i don't have any on hand. Labs show it and yeild differences line up with the cost of the light. I'm not trying to convince anyone, Simply inform them. It's all common sense grower. Allot of it can be ascertained by combining information on white & burple, weeding out the bs and focusing on what makes sense.

Just a hunch, but I assume youd suggest amare lights?

Like I said, I read his work, know the man, follow his advice and that of the company for all my leds, not just there's. Now I do allot better with all my lights. Come to find out none of the manufacturers were providing me with the proper Instructions on how to use their lights. Saying grow 6" - 12" at full blast n not having a clue how to use there afterthought additional cost, much needed supplemental rigs.
Coming off hps,cmh+Mh this was very frustrating and I almost quite leds and went back to the bulbs. Thank God I didn't. Now I love leds and the ones that weren't right to begin with I've since supplemented and use according to his recommendations. So hate the guy all you want, I owe him and the company my success. Which seriously has changed my life and financial situation to bigger n better things. Thank you Hybridway if you ever read this!

And brands come to mind you’d suggest?

I don't suggest. What, do you think I want other companies to copy their innovations so by the time they come back out with all new gear other companies have already reverse engineered it and found out the bulk of the answers by prying into their growers heads. Now, I'm straight. Goodluck tho.
My bad, I suggest Fhose, HLG, And everything on Shane's list, just from back to front. Lol!

The main goal for company’s to do is say there lights are better and get a fan club. Put pot leaf stickers on them and they will sell I’d say. Theres really something missing in most lights out today. Chlorophyll a and b are not compleat. It’s focused at 450 and 660. There’s very little 430 and 640 most absent is 430. So it would seem these would be more payed attention to as well. That and being able to adjust the red and blue spectrum to where the plant is in life. Some of the old blurple lights had 430/50 630/40 plus far red

Premature sent. And 660. They just didn’t have the full spectrum chip to round everything out. Anyway put it all together and that would make a good light with adjustable spectrum.

All good, I wish you successful grows from here til the end of times. I'll refrain from commenting on your posts in the future, but it's awkward trying to take your input seriously when you can't even own up to talking about yourself in the third person..

Nobody hates the guy.
But I don't remember his grows being anything special, or even on par with any average Joe on here.

So if your results are so much better there's only one way to show that and its not with words.
Show the evidence. Pictures, The lab reports, the yields.
The science doesn't mean anything without the evidence.
