Led Grow 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

Led Plant Growi Light. I’m doing a bigger experiment with plants. It will be a long time project and I will make a special page for this. It’s not the most complicated circuit, but I took the chance to design, after a long time, a PCB Board.They will be ordered at I will post an update with the finished Led Light in a good month or so.

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

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

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.
