I really looked into the LED thing a few weeks ago. I KNOW the tech is out there to make an LED grow light that works as well or better then MH/HPS. Issue is the cost, and a few companies selling set ups too weak in certain ranges to really produce the way MH/HPS can.

After looking at pics on weedfarmer and seeing the same thing over and over. I decided LED's are OK for supplimental lighting, but just don't have the intesity needed yet. HOWEVER, People who bought the MULTI-thousand doller German made LED panels were FAR FAR better(still not MH/HPS). Issue seems to be part of the spectrum(either orange or UV or both) the plant needs is still not there in LEDs. I'd guess the best thing you can do with LEDs right now is use them to add extra blue and red to your HID set up.

I wish this were not the case. LEDs will improve. I just could not for the life of me find pics of a crop that looked ANYTHING like an HID grow. I hunted for someone using both HID AND LEDs. But I couldn't find anyone doing that either. The spectrum output of both at the same time looks VERY promising.
