The post Light sensitive automated grow light appeared first on The Cheap Vegetable Gardener.
I came across this interesting concept for an automated grow light. It uses a photoresister to detect when lights get low and proceeds to turns on some red LEDs to provide the plants a few extra hours of light.
From my experience if you are growing indoors, your seedlings can use as much supplemental lighting as they can get and would recommend turning them on when there is light as well, but though still a very cool project.
This could be an interesting concept for something like a greenhouse during the fall/winter seasons though.
