Really? CFL maybe but there are dozens of LED fans that tell us HID growers that we're using outdated technology, their LED's pulling 200 watts at the wall produce better than a 1000 watt HPS, etc.
If anything LED's are overrated or people try and justify spending $1500 for a light when a $200 HID setup will yield the same quality and quantity. Regardless, why care what gets overlooked or undervalued? Just grow your weed with the lights you have. Harvest and smoke. We are growing plants correct?
