Q: WHY DO YOU CHOOSE TO GROW THESE GREENHOUSE TOMATOES IN SOIL OVER WATER?  A: “Before we built the first greenhouse we bought this tomato from a grower that grows them in water and another grower that grows them in soil. When we cut that tomato and put it in the refrigerator if we didn’t want to use the whole tomato, the one grown in water went flat, like soup the next morning. The one grown in soil kept its shape.” Robert Fahnestock, Fahnestock Fruit Farm of Lititz, PA at farmer’s market, Germantown Ave and Mermaid Lane.
