Led Grow 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 

First I disassemble a welding goggles.

Then I cut 2 green acrylic glasses and the size is nearly perfect

See the difference

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
