 It is a technique of growing plants in suspended air with the roots hanging inside chamber created to promote growth.
 The nutrient solution is sprayed in fine mist form to the suspended roots in calculated cyclic form for few seconds in every 2-3 minutes.
 Proper hydration and aeration for roots is important as per the need of the plant.
 Aeroponics is practised inside protected structures and is found to be suitable for leafy vegetables like spinach, lettuce etc. and some root crops.
 It is found to be very efficient technique for space utilization; in some cases almost double number of plants can be grown in aeroponics system.

Light: A light source enables the plants to photosynthesize and store energy.
Support structure: A medium, such as cloth/plate, separates the plants from their roots and gives them support to grow.
Water and nutrients: A nutrient-heavy mist in the solution chamber is absorbed by the plants root systems.

A. Root mist technique
 Roots of the plants will be suspended in air inside the panel.
 Nutrient solution is given through spray as a fine mist and roots should be always kept wet.
 The box will be covered and sealed from all sides to promote root growth and block the light penetration.
 Properly maintain and set the misting cycle: 2-3 minutes intermittent misting and then stopping and again misting.
 Plant growth is much faster.
 Temp should be maintained at 21-23 degree C and keep proper check.
 If temperature rises, immediately start the misting.
 90-95 % water saving is done.
 Suitable for all vegetables, leafy vegetables, root crops (beet, onion, garlic, potatoes).
 Not suitable for growing tall growing plants.
 Requires proper controlled environment.

B. Fog feeding technique
 Nutrient solution is distributed to the plant roots at a range of 30-80 microns.
 Misting is done through proper atomization.
 High pressure pump is required for fogging.
 Pressure for feeding /root misting: 80 -100 psi ranges.
 This system increases bioavailability of nutrients and requires nutrient in least quantities
 Roots should not be too much wet nor too dry and maintain proper moisture
 Set the misting cycle properly (2-3 minutes intermittent misting and then stopping for 2 sec and again misting.
 Both water and nutrient solution is saved.
 Suited for all vegetables, leafy vegetables, root crops.

 98% less land than traditional farming.
 Farming in Soilless controlled environment results in year around production.
 Requires 95% less water than standard farming.
 Minimum use of fertilizer in aeroponics system gives 60% fertilizer savings.
 Disease-free environment: As Greenhouse is well-maintained, chances of plant disease and insect infestation is very less and we can avoid soil borne diseases.

 Setup cost for aeroponics system is expensive.
 System maintenance: Disinfection of chamber to avoid contamination.
 Power dependency: if power supply is irregular, leads to reduction in yield or sometimes plant will die.
 Technical knowledge about the aeroponics system.
