This fully modular system enables you to grow each of your plants in separate pots. These pots are filled with clay pellets, and the integrated irrigation system distributes nutrient solution throughout. Each system features easy access to the tank including a detachable lid and a graduated inlet making it possible to quickly view the nutrient solution level. These user friendly features gives Platinium Hydrotar the advantage of operating in a wide range of environments. On very hot days it can function with the clay pellets which protect the roots.
