There is much to discuss when it comes to using Light-emitting-diodes as sole-source lighting or supplemental lighting for your grow operation. Some growers swear by it, while others vow never to go that route. The aim of this presentation is to briefly discuss photon physics and generation in LEDs, the interactions of photons with plant photosystems, and how you can run back-of-the envelope return on investment (ROI) and total cost of ownership (TCO) calculations.
