I was lost, it happens to me way too often these days.

I have been rethinking some of the design criteria in order to get max yield using LEDs. I am going with a couple of basic assumptions (please feel free to challange) that will be cornerstone of designs:

1. LED plant projects need to be SCROGed for max yield. The flatter the better.
2. I am going to shoot for 30 watts per square foot, vs the standard 50 watt per square foot used for HPS. I think most of us will be happy with a 40% savings in lightbill (or footprint).
3. Goal will be to achieve .5 gram/watt/mo harvests.

4. While energy efficiency will be the numero uno criteria, costs also have to be kept under control, just to make projects affordable at our level.
