The GrowGrip is primarily designed to work with leafy greens. We tested many varieties over the last year and our best producers are lettuce, spinach, and basil. Once you start growing larger plants, like broccoli, there is just too much force on the GrowGrip and the plants can tip over. In this case it's best to stay with net pots or media beds. The GrowGrip is designed for the "quick turning" plants that can be quickly planted and removed with little effort.
