    How far to keep your LED's / Quantum Boards from the canopy?

    This question about lights is probably as old as the first people who started to grow weed with electricity, and has been asked tons of times here too without end in sight. I didn't see a "real dedicated" topic about it either so decided to make one. Maybe some official or unofficial infotopic...
