Hydroponic Garden Tower Lettuce Grow. Your tower garden® can grow most types of lettuce. Stacking your plants is easy using this hydroponic tower.
The method, which entails growing crops in water rather than in soil, is not really a very new concept as it dates back to 600 b.c. Leaf lettuce and small to medium head lettuces work best, as some varieties of head lettuce with a stem larger than 1 ½” can be restricted in their development in the tower. If you want to grow leaf lettuce, this system is the best choice.
