Here is the LED light set-up that i bought through Amazon. I bought the 30 Watt unit, which I am guessing has more lumens compared to the 3 12-Watt fluorescent lights that I was using previously. LED has more light in the best wavelengths and wastes less of the Wattage on heat, so should be OK or better. The onion seeds have germinated so they will be an early test of the lights. The instructions state the lights should be 18 to 24 inches above seedlings or 12 to 18 inches above vegetables. This is between those heights. For onion seedlings I will time for 10 hours of light.
