Wouldn't it be more accurate and reasonable to compare the kilowatt per hour draw of a grow when calculating it's output weight's efficiency?
For example: Grow 1 takes 55 days of 12/12 to finish under a light. Under the same light, Grow 2 takes 70 days of 12/12 to finish. If both grows yield the same amount, it SEEMS like the GPW is the same, but in reality, the 70 day flowering took more power. Why do we not measure our grows this way?
Also, if we do measure like this, is it fair to include the draw of fans and other devices that are necessary to make the grow succeed?
