A very good insight to what happens during processing of foods. We have recently moved to grow our own, or as much as possible, foods. We are using what is called a waterless raised garden. It requires minimum attention, important in todays rat race, and can supply enough for 4 people in an 8foot by 4foot area. We intend to construct a second garden to provide for vine vegetables. If I had the luxury of space I would likely have more but I can dream can I not?
