The 4k qbs with added reds works out nice. But 3k anand 35k have nice 660nm bump in the spectrum.
Supplemental red lighting
- Thread starter budman410
- Start date
I have 12 4K an boards I was using for veg, the boards I ordered I could make half 4K they didn’t ship out yet. What do you think? I still wanted to to use the reds for Emerson.
That kind of driver is that, I need a low powered drivers just ordered some 120s. I’m thinking I want them pulling 30 watts max from the wall
Are they from rapid? Cost of setup?
Interesting. If I have all QB 3K boards 4x 260W at the moment - what do you think would be a worthy addition to aid flower? Is deep red out of the question when it comes to 3k?

No but the 3ks have a nice 660nm hit in them. You can throw some UV in with it. And some blues like 450nm if you're running a stretchy strain. I'm no expert by any means. Jus what I've flowered with over time. But when I run lanky OGs I run blues in with it. And keeps them short and stacked.
This below is an original 1995 OG kush gifted to me by s ling time family friend of my dad. He bought a bunch of packs back in the day. He gifted me 7 beans. I got 2 females. This is the keeper I kept. First run was typical lanky OG structure. Small golf ball nugs. This was second run. Run under f series gen 3s. In 3k. With 120w of 450nm royal blues from cree. And it completely changed the bud structure to stack like single cola Afghanis. Yielded almost 1 1/4 zips more than previous run without blues. So any time I run this cut. I throw my 150w royal blue bar in right in the center. Right at the onset of flower. And run it for the last 6hrs of the 12hr day cycle. I was amazed.
Doesnt look like OG Kush does it.....

Nice. That's
How I built my royal blue bar. 44" ling but its 4inches thick with 12 fins. So it dissipates heat fast so I loaded it down. Looks like a light saber lol
Sure. So the whole "adding 660nm" with a 3K is a bit waste of power or? Are the 450nm beneficial thru both veg and flower? Then I don't know
I hear 2700k QB aren't as efficient as 3000k, so I'm also holding off on that. Just wondering if there's anything I can add, even if more light is always preferable, the little things low watt would make more sense to me as I think I've reached my personal limit of wattage Just trying to optimize things further - and I think the Far Red is quite too little documented yet still that I wanna dive into it - a lot of lights are being sold with far red, but there's no actual guidance on using them really.. I'd like to know the real benefit of far red when used right..

It all comes down to the spectrum, type of strain and how you grow. There are alot of options now days, one of the big things that hold people back is money, the other is understanding what does what and why, one of the big ones that effects what people buy is motivation. Some people are motivated to get the best results and others can't be fucked playing around with spectrums to get the best results, they simply want to hang a light and go smoke a bowl.Sure.

Hey if you have any things I should read please reference them as I love to learn, I tried to search everything Far Red and Deep Red I could and ended up here

You have to try things out, I have had people do alot of grows under different spectrums and I really can't give a good answer, what I do know is that a broad spectrum works best across the range, some plants love heavy red spectrums and others don't. I have had very good feedback on FR for EOD. I am working on some new things to try out but so far that's where I am upto. I know that there is not one spectrum that suits all apart from sunlight.Hey if you have any things I should read please reference them as I love to learn, I tried to search everything Far Red and Deep Red I could and ended up here
Sure. Well I thought about the HLG 35 / QB18 6 Red, 8 Deep Red and 4 Far Red for instance. There must be a reason they chose Osram 120 SSL Deep Red and a mix of FR, Red and Deep Red here, thats what I'm thinking - and purposed to general use maybe? There are similar lights like this, but whether it's just blur I can't tell..

Usually people mix around 30% FR to 660nm. I am going to try something completely new for the next main test and do 120% FR to 660nm, but the entire spectrum will be quite different. It takes me a long time to get tests done here, would be easier if I was in a country that was allowed to grow it. I have given up on playing around to get the highest efficiency, I have done it and it's not important to me anymore. I am focusing on spectrum now because it's very clear to me that everyone has been missing something for decades with all this horticulture lighting, I think I know what it is but I want to be sure of it.

Yes the 3ks are better than the 27s. If you go with 3k QBs. Get you some blues to run along side it. And some FR for emmerson to shave a few days off. And try different methods. Like run the reds and blues for the first 15 mins or so. And find out which flowers better. Which controls stretch better. Which has better trich production. So forth and so on. I run 27s and 3ks mixed. 660nm and 672nm during first 10-15mins then kick off the reds. Kick on blues with my whites for the 6hrs. Then whites only for the last 5 hrs 45mins. Then reds only last 15.Sure. So the whole "adding 660nm" with a 3K is a bit waste of power or? Are the 450nm beneficial thru both veg and flower? Then I don't know

You are one of the people that play around to achieve the best results and you will get better and better at it, you know yourself that it's more complicated than simply hanging a light, it's difficult to get people to understand they need to think more like you though.

I appreciate it. I'm super stoked for all the info on the j series. My strip order of 100 count is suppose to ship today. Im ready to get building these monsters.

I'm gonna build half sized light for my personal and wanna send it to you to get actual testing. Jus tryna decide which way I wanna go with it.

I'm glad it's finally on its way, I think it will be a monster build. Cutter took too long to get them to you for whatever reason, one thing is the price is very good, I have seen the specs on the 5630 leds and it maybe a good option for a bit more efficiency once they have that board going.
