DIY Plant LED Light Prototype Lights Up The Winter
fresh veggies? This can be done by replacing the sun with an LED light, and Margaret Johnson, aka Bitknitting has been working on building her own LED plant light. She’s using a combination of red and blue LEDs that produce the ratio of light frequencies that plants thrive on, and has been experimenting with how bright to make them and how long to run them. This combination of factors determines how much light the plants get every day, called the Daily Light Integral, or DLI, and has a huge effect on how well the plants grow.
