now living in New Mexico, getting ready to build a whole new prototype system about 2000gals I think if it works then a 12,000gal system. tomatoes and Yacon, using native game fish, not to eat, but to selective breed for the south NM climate. hope to get some of the cutthroat trout New Mexico's state fish. yes I am aware of their water requirements particularly temp and cleanliness so will be a fun challenging endeavor. both yacon and tomatoes require heat, trout prefer cold water. opening new thread under "Back Yard Systems" titled "Are You Nuts!"
