I have long wished I could find horticultural lighting that didn't cost a fortune to operate. For several years, I've revisited the topic of LED lights for indoor growing. At last, their day has arrived.
At least, it has sort of arrived--because nothing is easy in the world of lights that grow plants. After all, they have to mimic that complex star that grows just about everything we've ever eaten or encountered, the sun. LED grow lights, it turns out, are good for leafy greens, herbs, and young seedlings. But don't expect to get an indoor tomato crop.
