So, I've been researching lights for my new grow, and was wondering whether LED is the way to go? Some of the panels on ebay are cheap and claim to emit the exact spectrum that a plant needs to veg and flower. Is this correct or are they just trying to sell them? Is it possible to veg and flower 1 plant with 1 panel? Or is it better to use the LED's as a supplement along with CFL's? Using LED's only would be awesome because of their low energy usage and low heat output, but does this mean low yields? It would be great to hear your thoughts!
