DIY My DIY LED, power supply and driver set up

[Talonxracer]

I have been running viparspectra quantum boards in my 2x2 grow tents but wanted to go a step beyond and couldn't find a commercial setup that tickled my fancy for a larger 3x3 grow cabinet so.........

The main light so far, 4 Crescience Fluxstrip cSpec enhanced strips(with LM301H-EVO Mint, LM301H-3500k and Osram Oslon square 4.24 leds), a 6500k Samsung lm301h sunboard cut in half and placed between the outer and inner strips, a lm301b 3000k cut into thirds(and using 2) placed between the inner strips and finnaly (though not presently on the heat sink) will be Starboards in 10nm steps from 385nm to 475nm and finally 680nm/720nm starboards for the Emerson effect

And here is the power supply/driver setup, (2)24vdc 150w and (1) 12vdc 75w meanwell power supplies, 16 drivers on 8 dual driver boards running LDD meanwell drivers, (each strip with its own driver) all being controlled by 2 Coralux Storm controllers allowing full dimming from 0% to 100% in 1% steps in manual mode and 256 steps in auto mode.

Wow, you seem to know your stuff

I know just enough to be real dangerous, LOL

Very little is good enough for me from the factory.

Well I plan on multiple plants for my next indoor grow(start Sept. 1st). So I had to alter my lighting setup from a single plant lighting scheme to one that will cover the whole grow. This setup pulls 228watts from the wall and when the cabinet is finished I will do a complete PAR mapping. I am waiting on new uva/near uva diodes on Starboards to arrive to finish the wiring for #3 and #8 strips.

L to R
Strip 1 and 10 are full spectrum C-spec enhanced LM301h/Evo mint
Strip 2 and 9 are 5000k LM501h for veg or 3000k for flower
Strip 3 and 8 have 680nm, 395, 405, 415, 425, 455 and 465 nm diodes
Strip 4 and 7 are C-spec enhanced for veg or LM301h ONE for late veg and flower
Strip 5 is a 730nm
Strip 6 is a 385nm
Strip 11 and 12 are the top and bottom strips and are 660nm

I have had a few friends who also grow, ask me why I am adding the additional LED's from 395nm thru 465nm, so I thought I should also mention what I am trying to accomplish with these additions in this thread I started as well.
If you look at chlorophyll absorption peaks there are 4. Chlorophyll A and B in both short wave(blue/violet) and long wave(red) spectrums. The chlorophyll A peak in the short wave spectrum has a lower peak at 398 nm and then plateau's at 405-410nm until 425nm which is the high peak for chlorophyll A in the shortwave spectrum. This is entirely missed with ALL so-called full spectrum LED lights. The next area that I address is the full beta carotene absorption plateau that ends approx at 475nm and most all full spectrum LED's have a substantial dip in this region.

Very clean build.

Is that 80/20 aluminum pieces?

Thanks!

It is standard 2020 profile with a 6mm t-slot. I know a guy who bought out a foreclosed computer/electronics repair store and they had a bunch(80 meters) of the aluminum profiles he didn't want to deal with so I bought it for pennies on the dollar. I even built my grow cabinet frame/skeleton out of it, with 1/4" ply panels. The 1/4" Luan plywood is not 1/4" but 5.2mm and after adhering mylar/vinyl film to one side the plywood fits snugly in the 6mm slot! Perfect!

One thing I discovered using the 2020 t-slot extrusion is that the open t-slot area under the strips gets rather warm/hot. Captured/stagnant air doesn't transmit heat well (think double pane windows) and a thermal viewer showed the heat. So I went and drilled holes every 50mm(just like drilling access holes) and with the thermal viewer you can see the heat plumming out of those holes like mini tornados, LOL!

@Zaaboot thanks for the rep and glad to have provided useful info!

I got the control panel for the new cabinet up and running, it has 3 Coralux Storm controllers, 6 channels each, one for UV/near UV, the second is for blues/violet and the third is for reds and full spectrum leds. Also incorporated into the panel is a AC Infinity 67controller and finally a 12vdc timer that I used for a turntable(but can be used for hydro).
