DIY 4x12 3500K/5000k lm561c two channel board

[Dave455]

I have been running a 200w GrowGreen board on a 240h driver at full power that is 230w 2 amps since these boards were designed and fabricated.

The boards work fine provide great light low heat are electrically efficient, uses a small led driver 185h- c1050a low amperage high power.

The detractors can say anything they have not used a GrowGreen board or even touched one but they already know everything about the boards except they work great replace four cob 200w unit all day long with lower powered drivers and less heat. These are facts.

Like some more info on boards ? web page, ?

If we're supposed to wire the channels in series for a single board, I'd recommend on the next iteration flipping the positive and negative side on on channel that way the channels line up as follows:

C1 C2
+ -
. .
. .
. .
. .
- +

For ease of connection. Otherwise great board, cheers! Out of curiosity, what are these connectors called on the pos and neg?

They call them solderless or wago style. Go figure. Thanks for the kind words.
The way the diodes lay they all face the same direction so positive on the board is also positive on the string for users and manufacturing.

I am asked on a regular basis why I mix 5000K diodes with 3000K diodes on one pcb and two channels.

I chose to go this route as it is a more cost effective manner to add more 460nm - 475nm light spectrum from the 5000K diodes and add the 650-700nm Deep Red in the 3000k diodes for a great growth combination.

460-475nm Royal Blue is considered for the ability to reduce stretch in plant growth. That is one aspect, but there is a more important aspect to using 460-475nm light spectrum throughout the growth cycle of cannabis and all plants, that being 460-475nm light spectrum provides an energy boost to the plants growth process. There is another aspect to this light spectrum, as well, is it adds flavor and aroma of flowers during the flowering stage.

In daylight, there is 460-475nm light spectrum in the light all day long, all year long.

650-700nm Deep Red is mostly considered for adding stretch to plants during flower phase, but there is much at work. 650nm -700nm allows peak chlorophyll's and photosynthesis , already well known. Perhaps lesser known is the ability of 650-700nm to increase antioxidants and improve flavor of flowers.

So both light spectrum work together to enhance flavors, size, taste and aroma. All that is left is the THC development, UVA, another discussion.

One method to provide The necessary 460-475nm light is to add a channel with Royal Blue diodes at 460-475nm as other's have done, or to add the 5000K to the main spectrum available, which peaks at the 460-475nm spectrum, great for adding that additional light spectrum at a less expensive cost and still get plenty of "white" light and watts.

The same is true for the 650-700nm using the existing in the 3000K light spectrum. The 2700K light spectrum will provide a little more additional 650-700nm and the 460-475nm will provide the additional energy needed to take advantage of the 650-700nm light spectrum enhancing growth during vegetative and flowering phases.

Hmm!
Why not adding 4000°k for more light blue/cyan instead of 5000°k?
It has about 6% more blue in the 460-475nm range?
And BTW,
all white LED's have their blue peak at ~450nm, which is called royal blue, but 475nm(light blue) is always the lowest part between the blue and green part of the spectrum. Seems you have twisted something...

Apart from this I'm curious to see gen.2 in action. These multi LED boards are really underestimated for it's capabillities.

Here is my Kitchen garden with two no till earth boxes sips containers on season two. We have micro greens kale cabbage collards spinach and many others under a GrowGreen 20pw board driven at 50% or 100w and 30 inches above the garden with no stretch.
This is a 5000k/3000k mix spectrum board.
PPFD numbers have been posted prior.
Enjoy

Look how your cheekily maracuja* loves your ggboards...
Soon she'll hang horizontally under the board, if thats keeps growing....

*is'nt it?

the tomatoes love the light,and the mint fights for first rights.I love having a kitchen garden with fresh herbs and greens. I use a ITEAD Sonoff to control time schedule. I just wire into the power cord and pair it with my wifi and I can turn the lights on and off with schedule and manually.
thanks for checking in.

I have some new companion boards being manufactured to go with GrowGreen boards or any white light diode setup.

One is a two channel Red/Blue Sunplus 20 2:1 ration Red:Blue using an MW lpc-60-C1050 driver for each channel for 75w total power
The Second is a Far Red and 385 UVA using Sunplus and a choice UVA diode of my choosing that is high power using an MW lpc-60-C1050 driver for each channel for 75w total power

I will have these available on my web site very soon. The diodes I used for the prototype I built, I bought diodes from Stevesleds on sale at $2/diode for 36 diodes $72 plus soldering, solder, heat sink, etc.
peace

How big are these blurple strips/boards? More than 2ft.?
I did not find any info about the dimensions on your website, but they sounds interesting.

I'm looking for 2ft. strips using SunPlus20 (12,5:87,5%, pinkish) or their freshmeat/1900°k SMD3010 diodes but did not find any and since I need only a few of them It is not worth having them made. But found a "fresh-meat tube" using 1850°k smd5630 diodes made by Sanan, 60pcs per 2 ft. tube.(12s5p) I'll try to get a few samples because the tube sellers like to sell only by bigger margins. But I know nothing about Sanan and I would 10 times rather get SunPlus20.

The reason I choose the 5000k is it has more penetration than most other spectrums, which is why I decided to add a Royal Blue and Deep Red accessory board to improve the blue.

 

[VegasWinner]

The new boards are 1" x 12" small but powerful fit on smaller heatsinks available as 25mm x 300m size

 

[stxfarmer]

Just wondering why UVA and no UVB?

Probably too expensive..
UVA LEDs are 3-6x so expensive as white LEDs and real UVB/290nm LEDs are almost priceless.
1m no-name stripes cost about $ 120 and offer only a few watts.

On the second companion board what is the breakdown of the diodes? What is the ratio of Far Red to 385 UVA and the high power UVA diode? Am I understanding this one correctly in that you will be using 2 different types of UVA diodes? Sorry but a little confused about the second board.

I will be using just one UVA style diode four in total .

The Far Red is an independent channel from tjhe UVA channel that has 24 diodes for a Vf of46.8v using a C1050 driver you get 50w enough to cover a 2x2 area.

The UVA is 3.5vf and four diodes at 1050ma gives 15w enough to cover a 2x2 area as well.

Just wondering why UVA and no UVB?.

UVA 385nm promotes taste, color, and terpins for flavors. UVB promotes sunburn and skin cnacer but retpiles love them and certain aquatic flowers love UVB,

The Deep Red 24 diodes at 46.8vf @ 1050ma for 50w to cover a 2x2 area. Royal Blue is 12 diodes at 33vF @ 1050mA for 35w enough to cover a 2x2 area

Each of the two boards is designed to cover a 2x2 area so you would need four boards to cover a 4x4 which would use one HLG-185H-C1050 driver for each of the four boards Deep Red Red channels and one HLG-185H-C1050 driver for the four boards combined Royal Blue and UVA channels wired in series. Another HLG-185H-C1050 driver for the four boards Far Red channel should work fine.

The calculator
58w for Deep Red- 58 umoles
36w Royal Blue - 97 umoles
50w Far red - 73 umoles
total 273 umoles

Pretty cool tool. Is there a calculator to do mono diodes? Im building a 256 mono 3w diode light. It would be cool if there was something to add a diode, and it shows on a chart, the more you add, the higher the nm goes and so on. I was just wondering is all.

There must be an issue anywhere in the calculator.
The calculator say 0,14μMol/j for the far reds at 1A, so 51w can not be 73μMol/s ... it's more a tenth.
Seems the comma has slipped by one point!
This would also indicate that far red drives photosynthesis better as royal blue which is simply not true.
1,26μMol/j seems also not very efficient...
You also changed the calculator values for red and blue in your last post, which is a bit misleading. Either you write too fast or you do not sleep enough.

Why not try T5 arcadia 12%......39 watt tube.....run entire on period.

the manufacturer may have a calculator fr the diodes you are using

I am sure there is an area factor I have not considered.
