I was thinking about using solar power for grow lights. Maybe setting up a few panels and charging up batteries during the day. Not sure if this is too out there or if it would even work.
Maybe using the LED lights since they have less energy requirements would make solar more doable. But even the 40% or more energy savings compared to HID lights might be too much to reasonably expect a solar system to run.
From my quick research, LED lights are recommended. Most say it is not worth it financially but I am still reading up on the science. It would be beyond awesome if I could get a solar light set up going.
