I read an interesting article by Ben Burkhardt, who once owned the largest indoor grow facility in the country. He found that there was no simple metric for yield analysis which took into account not only the power used by lights but also the length of flowering time. Often yield is stated as grams per watt, but that doesn't take into account the difference between a plant that finishes in 45 day versus a plant that takes 90 days. He put forth a metric that takes both into account and works for the closet grower as well as a huge commercial grower, and returns a number that can be compared across any grow type.
The equation is as follows: Yield in grams ÷ number of 1000W lights ÷ days in flower = GPD average.
As an example, my three plants were under 1600W of leds and took an average of 90 days, and yielded 3000 grams of dry flowers.
3000g ÷ 1.6 ÷ 90days = 20.8 grams per day.
Here's a link if anyone would like to see the source material.
