An aeroponic system grows plant roots in air and sprays them with nutrient solution on a timed cycle. Because the roots are exposed, they dry out quickly if the misting stops.
The cycle
A pump and timer spray the roots at set intervals. The interval and spray length depend on the plant and the system, so follow the manufacturer’s guidance and watch the roots.
Why timing matters
Too little misting dries the roots. Too much can keep them too wet. Check the roots and adjust gradually.
Backup power
Because the roots dry out fast, many growers plan for power cuts with a backup supply or an alarm.
