I need 2 Led lights with a length of 90cm. They will have 2 times 300 Led's and 12V/2A each one
It will be a mix of red and blue Led's. Green is not needed, because the plants reflect the green light
First, I wanted to buy 2 or 3 Led grow lights, but they were too expensive or not what I needed. So I decided to build my own Led light

My red blue grow lights are good for my plants, but it’s a not very natural light for my eyes. When I look through green glass it looks much better. So I build me a green glasses and it looks very stylish

After I saw that my Led lights work on plants I started to solder the other PCB's.
I'm using a cheap 600x microscope to solder the Led's.
The pictures has been taken with a green filter in front of the camera lens.
My plant light works. The first seed starts to grow. I’ve done a timelaps video over the day, with one picture every 60 seconds. Playback rate is 25 frames per second. I’ve slightly zoomed in and I layed a green filter over the video to remove the maximum of the pink light.
This will be my first attempt to check if my growing light works. I use coir pellets witch provide a lot of substrate and as seed I use salad burnet herb. I took these seeds because of there size.
A small plastic Tupperware will work as a peel for my vegetables. With the addition of water, the pellets swell up. I press the earth over the seeds and put the whole thing under the light. Now I have to wait if it works or not. I also added a thermometer to check if it’s not to cold in my workshop.
Crossing fingers.
I just finished the first of the twenty grow lights.
Works great and as I calculated, it takes at 12V DC 200mA.
I use my laser cutter to build a mask that will hold the Led's in place to make the soldering easier.
I used www.pcbway.com to make the boards and here is the result, 25 nice white PCB's
Here is the Schematic and the PCB design, It's made with Diptrace

Hi, I did buy them over Aliexpress. Not fast but cheap :)
eager to see how well this light pans out for plant growth as time goes on. Would be a nice drop in replacement to my LED grow light design on here from a few years back.
Hi, the plants are still growing. I'm not a gardener but it seems to work. The second plant start growing 3 weeks after the first one. I'll will post photos of the plants in a few days.

do you know how many Watts your outputting per panel?
im actually interested in buying some of these off of you! i have a very teeny tiny grow box that needs supplimental lighting on the sides AND from underneath,... and this is PERFECT for what i need! and technically i could arrange the diodes in any order i wish right? such as alternating color (RED/BLUE) every row, to spread the spectrum out a bit
