Willie and the Salad Bonanza is a contest open to elementary, middle and high school teams, along with other K-12 community organizations such as 4-H, scouts, FFA or other teams, interested in the scientific principles surrounding plant growth. The challenge is to grow the largest amount of spinach, kale, and looseleaf lettuce in the same container. Plants may be grown hydroponically, or in soil, and the one yielding the greatest ratio of biomass to volume wins.
