This type of hydroponic system grows the plants in a porous material like clay pebbles, vermiculite, fiberglass, coconut husk and perlite that holds water. These types of medium also allows for air to reach the roots limiting the possibility of root rot. The nutrient water is run through the material to keep it wet and the material keeps the plants roots separated to allow a good contact with the air, helping the plants use oxygen and carbon dioxide to produce healthy plants. This type of hydroponic system is easy to use, set up and control if you’re growing many plants. You really need to come by our hydroponic store in Gainesville Florida for help choosing which system is the best for you.
