The Foody 8 Hydroponic Tower is our ideal system for outdoor hydroponic growing. Each growing pod has 8 planting pockets and there are 8 pockets for net pots in the base providing 40 total planting locations. Towers include both anti-oxidant and UV reduction elements that help reduce algae formation. No need for messy potting soil. Growing pods are attached to base on ball bearings, allowing the pods to rotate easily for optimum light exposure. This system encourages rapid plant growth by circulating water and nutrients from the base reservoir through the growing pods which hold the plants.
