The aeroponic system is probably the most high-tech type of hydroponic gardening. The growing medium is primarily air, but unlike the NFT systems shallow channels, the roots are growing down into a much larger container . The roots hang in the air and are misted with an oxygen rich hydroponic nutrient solution. The mist cycle are usually done every few minutes.
A timer controls the nutrient pump much like other types of hydroponic systems, except the aeroponic system needs a short cycle timer that runs the pump for a few seconds every couple of minute.
>Interval cycle timer- 1 hours running every 30 minutes . The timer is specially designed for aeroponics system,in order to prolong the life of the mister.
