To add to Mac's list of LED benefits, with the reduction of ambient temperature and decrease loss of moisture there is less "smell" during the flowering stages with no decrease in the taste and smell in the finished dried bud.

So far my high intensity LED grow is producing buds of similar size and density and extremely low stretch. My theory is to use the same number of watts per square ft as HPS and see the results and so far so good. The up front cost is quite high right now, but as the market matures the prices will come to the point where HID is now.

I don't even want to think of how much I paid for my first 2 - 1K HPS/MH setup back in the 80's. I had friends who were fellow growers that were laughing at my concept of growing indoors with "light bulbs".

The world keeps changing my friend and I, as always, want to go "furthur".
