As we already established this in previous blogs that in hydroponics plants are grown without soil, using nutrient rich solution provided directly to roots. Aeroponics is an advanced type of hydroponics system where plants are not fully submerged rather sprayed with mist of nutrient solution.

Aeroponics Overview:

Aeroponics comes from Latin words meaning ‘Air Labour’. To simply put its an alternate technique for soil-free cultivation in conditions that enhance development. Aeroponics is a specialized type that uses no soil and little to no nutrient solution. It seems as if plants are floating in the atmosphere. The plants lower stems are suspended in the tank using biodegradable foam.

Since the roots aren’t submerged in water solution the plants can breathe plenty of oxygen and the nutrients are provided using ultra fine sprays, pointed at roots. Roots are sprayed such as fine layer of nutrients cover them and the rest drips back to the bottom of tank that again gets reused for the next cycle. The spray works at a predetermined interval and a very minimal solution goes to waste in the aeroponic system resulting in insane growth rates and yields.

If you are a beginner hydroponic enthusiast we would recommend you to steer away from aeroponics as its tricky and sensitive. But if you have had some experience with such systems you will be able to achieve cheaper yields and a little amount of nutrient solution will go a long way.

Keep in mind though, these systems aren’t ideal if your plant is going to have long dense roots network, then we would steer you towards a system that can accommodate larger root masses. Using these technique the nutrient rich liquid is provided with extreme precision resulting in quick growth. you will need to take certain preliminary precautions as the system can collapse if the spray holes clog causing the roots to dry out as they solely depend on spray cycles.

For this system to work well, it is important to maintain proper temperature and to make sure that the necessary amount of nutrient-rich mist is available.

Key components:

Root System

 The plants are hanged in a container where roots are suspended in the air.


Nutrient solution is stored in a reservoir underneath the roots from where the sprayers takes water and the droplets fall back into, hence leading to no wastage.

Mist Spraying

Thin whole sprayers mist the roots with nutrient rich solutions at specific intervals.

Control Unit

Many systems have a fixed temperature and mist control setup.

Advantages of Aeroponics

Productive with rapid growth

Compared to soil-based farming, this method is more sustainable as it uses almost 90% less water.  If you aim to go fully commercial in this field, you can grow more food, healthier types and also more profitably because you can use height and air as a growing place.

Air Exposure promotes sustainable yield

As aeroponics uses air to suspend plants with spray of tiny drops of water, it is ideally suited to promote rapid plant growth. . As a result, compared to soil-based farming, more plants can be grown in less time.

Oxygen rich environment without land

If you have a place in your tiny garden or on the roof, you may use it right now to grow your food. To experience the beauty of aeroponics you can even build small system in your living room or balcony.

Disadvantages of Aeroponics

Although aeroponics provides numerous advantages but it requires special monitoring and care. If you are going to setup an aeroponics system make sure to be properly trained and be willing to upgrade your abilities by trying new technologies. Artificial light plays a vital role in success of such systems. In indoor systems you will have precise control over the duration, intensity and spectrum of light.

Aeroponic Plants

You cant grow everyplant in aeroponics, the most suited plants are green leafy items and herbs along with strawberries, tomatoes and cucmbers.

Although root and tuber crops are less common in this system, you can still cultivate them if you have access to the most modern infrastructure.

Aeroponic Vertical Farming

Vertical farming involves stacking layers of plants to maximize space utilization. Artificial lighting can be strategically positioned at different levels to ensure that each tier receives adequate light. This ensures uniform growth and development throughout the vertical structure.

To make your vertical farm successful you need to look into the following:

  • Conditions your plant require, for example: water, light, temperature, humidity etc.
  • Mist sprayers are not clogged and operating per interval

Hydroponic Farming: What not to do!

Hydroponic farming system of vegetation uses liquid nutrient solution. Water based minerals are fed to nourish plant growth. By adjusting the quantity of nutrients, sunlight and water plants flourishes more as compared to traditional ways. Typically an inert medium or substrate is used along with air pumps, air stones and wool. Recently a majority of commercial hydroponic systems are used because of its higher yield value. Even though the system is extremely mechanized but proper supervision is necessary to get ideal production.

Traditional farming involves the ploughing of soil prior to plantation which is very time consuming. While in hydroponic farming, ploughing is eliminated from the whole equation which makes it quite easier and stress free.

What are hydroponics techniques?

There are various techniques that are used, but the principal of hydroponics system are essentially the same for every system.

Hydroponic systems are generally categorized as water based or medium based systems.

Water setup does not require an inert medium to support the roots, only needs the liquid nutrient solution. Whereas medium based setup needs a solid substrate, such as rock wool, moss, to strengthen the plant root structure.

Both setups can be open or closed. Incase of open setup liquid solution flows through the roots just once and the rest goes to waste. In closed setup the extra liquid nutrient solution is recycled and sent back to the system roots.

Revitalizing the liquid nutrient solution:

For open setup the water solution is used only once and discarded. In close setup water solution after once used is examined for ph and minerals, then refreshed, and returned to reservoir tank.

Neutering hydroponic medium:

Inert medium based hydroponic systems are inclined to pathogens attack so it is advised to sterilize the setup between each yield. It can either be done by steam sterilization or by chemical sterilization (using bleach).

Pest and disease control:

Integrated pest management (IPM) is the most eco friendly method for both commercial hydroponic systems and complete indoor hydroponic systems. It requires frequent checking and uses a range of managing techniques that varies from plant to plant. Certain thresholds are also set to identify pests and other factors.

What are 5 specific examples of plants that can grow in hydroponic systems?


Tomatoes are one of the most highly grown vegetable hydroponically, whether you grow cherry or traditional ones both commercial and home grown produce yields best results. It takes about 6- weeks to harvest. Tomatoes require more light but it can easily be grown indoor (using grow light).


Lettuce is among the fastest and relatively easy growing hydroponic plants. It has a big market value as it is used in making fresh salad to a 5 star meal. Ideal ph required is 6-7 . It takes approximately 4 weeks to harvest.


Among fruits strawberries are the most sought after because of its countless use in recipes. You can enjoy fresh strawberries all-round the year hydroponically from comfort of your home. They take about 6 weeks to harvest.


Hydroponic farming is famous for its best growth results in all species of mint. Their roots spread rater quickly, and have overall faster growth time.


Growing beans is generally considered easy and requires low maintenance. It has a steady market demand and can be easy grown using hydroponic system. Ideal temperature requirement is warm with ph 6.5. It takes about 8 weeks to harvest.
