LED yield results from the rui community, Refuge from HGL threads

[boilingoil]

Ok, now this thread is producing some useful information. As @boilingoil has stated it is about the the ratio of R : Far Red. @rkymtnman needs to somehow factor in the reds that are already in his base white led's.

This brings us to the heavy science part. If I have say 500W of the below spectrum, how would I determine the quantity of Far Red to add to get to the proper ratio?

Your more than welcome to contribute to this thread. To do the math for it requires a lot more data than just the SPD. Play with this for awhile and we can discuss it some more later. https://www.waveformlighting.com/led-spectrum-simulator.
I'm heavy into my veggy garden planting right now.

Right now in bloom I have GG4 and Grease Monkey, and I have some more Grease Monkey, GG4 going into bloom as soon as my other room is finished hopefully by the end of the week along with Forbidden Fruit and Gelato. I've not flowered out Forbidden Fruit or Grease Monkey yet so I don't know how good they are but the GG4 and Gelato are spectacular. And I have a shit ton of seed going too lol.

I thought grease monkey wasn't available anymore? I remember someone showing it a year or so ago and it was just pure frost.
Is it from cut? If from seed where did you get them?

So why are so many companies trying then to re-create sunlight?

Because the sun has proven to be the only thing that every species of plant performs properly under.
I do agree that with led the focus needs to be on researching what it is specifically in sunlight that allows plants to utilize it the way they do and focus on those aspects while trimming out those of no importance.
This whole "species specific" lighting thing is all fine for growing in the lab in test tubes but in the real world growers want a light that can literally grow anything they hang it over

That's true they aren't available anymore but Exotic did re-release them this year but he didn't use the same exact male, he used a cookies n' cream F2 male vs the original. But what I am growing is a cut of it from someone that grew the original, I also have around 30 selfed seeds from a keeper pheno from a good friend. I did grow out 2 packs at one time and I remember opening up my tent one day and I felt my heart drop into my stomach because I thought I had PM.. I had 2 phenos from those 2 packs that were unbelievably frosty, it was something you'd have to see to believe and pictures didn't do it justice.. The cut I have now I am not overly impressed with yet, but there is still 3-4 weeks to go..

I remember when I saw it on the frostiest buds thread, I was in shock, but then heard it was prone to herm and discontinued.
I can only imagine the joy of opening the tent and seeing it in person.

Will have to keep an eye out for your grow man.

Plus I have a lot of beans en route so if you ever fancy doing some swapsies give me a hola.

I see where others here are able to like posts but I only have the option to reply. Was trying to send a like your way. Any insight into why I can’t like your post or anyone else?

Maybe not enough posts?

Eventually all plants have the ability to adapt to their given environment. Look where all base vegetables come from different climates from all over the world but have been modified over time and to some extent genomic engineering to grow in less than optimal climates.

slow down with all this knowledge you're dropping on us. lol.

i think i fried my brain trying to use that spectrum simulator you put up a few posts ago. hahaha.

did you see that photon 2000 light they make? it seems pretty well made and not too expensive. i've never heard of it on this forum as anybody growing with it though.

The problem with the simulator is it needs to be narrowed down to actual chips wavelengths then be able to overlay the base spectrum for comparison and adjust from their.

it is definitely not user friendly for a newbie that's for sure. i was able to get close to a 4K white chart just by hit and miss. but in the right hands, it's probably useful as hell.

 

[coreywebster]

There was a big time fanboy over on the Exotic thread saying anyone that gets hermies from Exotic is either lying or doesn't know how to grow lol. I could inbox you with what seed I have if you want?

lol I can imagine!!
Yeah man send me a DM man.

the key spectrum addition is cyan

can't be that vague on this thread.

elaborate por favor.

Just something GrowMau5 said a couple years ago on a podcast, he said Cyan is the missing spectrum in most lights, and adding to your rig if possible, would be very beneficial. 480-510 target nm. Not sure of a recipe for addition, or watts per foot print. Maybe fall in line with maybe 50% of the Far-red values ( 730nm ) ..

I run luminus, and i can tell ya, I have almost none of it. I plan to make a Far-Red bar using monos and lenses, and going to incorporate cyan in it myself. I have to go back and find the pod-cast, but i think it doesnt exist anymore when utube did the wipe last year.

thanks. i've seen cyan diodes but never thought twice about using them. i thought they were maybe aquarium specific.

seems like a lot of us could use strips or a bar with either/or deep, far or maybe cyan to supplement our QBs. hell, even chuck a uvb diode or 2 on it.

Pics please

I'll try and get some posted up tomorrow.

Cyan is the missing spectrum in blue-based diodes, but UV-based white phosphors have higher levels of it, and that's part of the reason we used them in the High Light boards, to fill in the gaps and extend the spectrum into the near-UV/UVA range.

Here's a comparison of typical blue pump LEDs compared to Nichia's Optisolis (420nm pump) from their spec sheet (Optisolis 5000K spectrum in red):


Here's a Seoul Semiconductor (410nm) 6500K:


Here's a gif of Yuji LED's VTC range (400-405nm):

sounds great. im tempted by the Gelato, smoked some at Spannabis that was right up my street.

Well, good luck with everything, dude. please let us know if you journal it, im sure most here would love to see it. cheers!

yeap, there it is, thanks for the post and reference.
