DIY LED Growlights from LED Xmas bulb strings Answered
I just got an Aerogarden for Xmas and it is a pretty neat little unit, but it has some annoying and expensive problems. The biggest one is that it uses CF bulbs that are on 16 hours a day, and they say that you need to replace the bulbs every 6 months, because the spectrum of the bulbs change as they age, making the plants grow less well. I did some research and found that the Weed industry has created a solution: LED arrays with a combination of red and blue LEDs (the color frequencies plants thrive on). These arrays are very long lived and use less than 1/2 the power of the CF bulbs in the Aerogarden. The problem is that even the cheap ones (200 LEDs) are $50, and you would need 2 for complete coverage in the Aerogarden. Then I had a brainstorm! LED Xmas Lights. They are already wired, ready to mount on a panel, and you can get Red and Blue strings of 100 on ebay for about $10 incl shipping. I don't know if they are the right Red and Blue, but it is an interesting experiment. Even if it does not work, you are set for Xmas lights for next year.
