Growing power seem to have a winning combo going. I underestimated what they are doing. If the information in these videos is true then on 3 acres they are producing 1,000,000 pounds of food each year! How are they doing this?

10,000 fish
300-500 yards worm compost
3 acres of land in green houses
Grow all year using heat from compost piles.
Using vertical space
Simple 1 pump aquaponics

A packed greenhouse produces a crop value of $5 Square Foot! ($200,000/acre). That is if the whole acre was under greenhouse.
