Tommy (the tomato plant) is growing quite nicely.
Tommy in our Kitchen
Yippee! Starting to Flower
I’ve decided the LED light I am using from LEDGroupbuy.com – the Lumia 5.1 – will work for tomatoes.
This light has 5 channels, each needing a constant current of 700mA. It also gets really hot, so it needed a heat sink. I ended up mounting the light on a CPU heat sink
The CPU fan/heat sink works extremely well at a price around $25.
I used 5 MeanWell LDD-700H constant current drivers (data sheet)
hooking each channel of the LED to one of the LDD-700H drivers that I mounted onto a breadboard. Wiring it all up and putting a reflector around it got me this FrankenLED:
Bwa-ha-ha …but it works…
The LED is plugged into a power supply I got from LEDGroupBuy
so that’s Tommy. On my next post I will be building a PCB for a light fixture to hold three of the Lumia 5.1s to expand the number of tomato plants I will grow in my kitchen.
