Aeroponic garden, is a technique of growing plants in a cavity bucket containing substrate rather than of soil, hanging up from the surface. The roots of plants went down of the buckets, where a mister mist the nutrient solution directly to the root zone. Hence, plant has to consume less energy to grow its roots for nutrient searching. Which also benefits the stem of the plant to grow well.
Use of mister gives higher nutrition as well as good amount of air required for the better growth of plant.
