Aeroponics system: Definition and How Does Aeroponics Work

Posted On : February 16, 2021

What is aeroponics?

Aeroponics system is a new type of plants growing without soil and with small amount water. This makes a bit strange, Aeroponics system is very efficient and effective type of growing a many variety of plants. By Using this systems means you can grow plants horizontally as well as vertically, so it can be a great method and helps of saving space. NASA in space station did few experiments and found that the Asian bean seedlings they grew using aeroponic system on the space station in zero gravity grew very well than the same plants on Earth.

Aeroponics system plants are insert into special A frames or horizontal boards, in particular way that both the top of the plant, the crown and the bottom of the plant the roots are suspended in the air. In this way the plants can grow upward and the roots goes downward without needing any soil at all. The growers of Aeroponics system feed the plants by using spraying them on a regular basis with a fine mist of a water-mix solution,nutrient-rich. As the whole system is enclosed and you can save water because the nutrient mix is fully recycled within the aeroponics systems design.

Because Aeroponics system that allows very high-density of planting and this makes harvesting very easier,farmers find that they get high yields. In Sardinia, Italy, researchers found that tomato plants are grown in aeroponically method and produced four crops a year instead of the common one or two.

In addition, because aeroponics is so appropriate for small indoor spaces, one group of growers especially people that grow marijuana has found it especially useful for his or her specialist crop. Other gardeners involved within the urban gardens movement also find that aeroponics could also be an honest thanks to grow fruits, vegetables and herbs in their apartments.

How does the Aeroponic systemwork?

In the aeroponic system plants are usually put into the top holes on top of a reservoir and also placed within a sealed container.

Due to no root zone media for plants to anchor in, you would like to organize a support collar which will hold stems in situ . These collars must be rigid enough to carry plants upright and keep the roots in situable place but flexible enough to permit room for roots to grow.

The pump and system creates vapor which may be a hydro-atomized spray mixture of water, nutrients and growth hormones out of the nutrient-rich solution and sprays the mist within the reservoir and engulfing the dangling plant roots and absorbed by them. This spray creates the precise amount of moisture content which stimulates the plant’s growth and makes it to develop turgidly.

The timer allow to supplies the timed spray intervals and duration for the plants regularly. Most of people think that growing plants in aeroponic system would be frailer when compared with hydroponics. But that’s not true. the key of aeroponic system all lies within the amount of oxygen exposed to the roots without a root zone media limiting it.

The aeroponic system plant roots will develop and grow rapidly during a moist air-rich environment. If you would like to verify their development rate, just lift up the growing chamber to ascertain how they're growing.

Types of Aeroponic Systems:

Low-pressure Aeroponics

This is the most commonly used aeroponic system type used by most of hydroponic hobbyists due to its ease to set up, availability at any hydroponic shop, and its very low cost.

And in Low-pressure it creates droplet size much different from the high-pressure aeroponic system.

What you would like for this technique is simply like all hydroponic system – a pump strong enough to move the water onto the sprinkler heads to spray water round the plant root zone.

High-pressure Aeroponics

High-pressure of Aeroponics is latest and advanced one and more costly to set up as it would require specialized tools and equipment. So they are often utilized in the commercial production instead of home growers.

The HPA must run at very high to atomize water into tiny water droplets of fifty microns or less.

This system creates such a fine droplet size that make more oxygen for the basis zone than the LPA, making it the foremost efficient system among all aeroponic types.

Ultrasonic fogger Aeroponics

Ultrasonic fogger Aeroponics also called as fogponics and is another interesting sort of Aeroponic system.

The farmers would use an ultrasonic fogger to atomize water into small droplets of water. These are very tiny and you'll see it within the sort of fog.

Though plants roots find it easier to soak up water in tiny size there’s little moisture within the fog created and when running over time it can easier create the salt which will clog these foggers than other Aeroponic types.

Plants to grow in Aeroponics system?

You can use this Aeroponics system to grow nearly any sort of plants and cultivars like vegetables, bedding, garden plants, and nursery. quite many species of plants had been tested and planted successfully by commercial greenhouse owners, researchers and nursery operate using this Aeroponics technique.

Tools needed for Aeroponics system:

What you will need:

  • A reservoir/container to hold the nutrient solution
  • Nutrient pump
  • Mist nozzles
  • Tubing to distribute water from the nutrient pump to the heads of the growing chamber
  • Baskets to suspend plants
  • Enclosed growing chamber for the root zone
  • And watertight containers need for the growing chamber where the plant’s root systems are going to be
  • preferable a cycle timer needed for on and off the pump

You can buy all kind of tools at the local gardening/hydroponic supply store or you can buy trough online.

It’s quite easy to know how an aeroponic system works. the aim of the plant roots hanging in mid-air is to urge them exposed to oxygen the maximum amount as possible. The high volume of oxygen exposure will stimulate their growth and help them grow faster than they might within the soil, which may be a vital advantage of this sort of system. this will be seen within the massive root growth of the plants. it's also been proven that this system increase crop yield X10 compared to using soil. Not only will you be ready to collect healthier plants but also grow more crops per annum .

No growing media is required with aeroponics. you'll use baskets or closed cell foam plugs (compress round the plant’s stem) to suspend the plants. These tools slot in the tiny holes on top of the growing chamber. within the growing chamber, the mist nozzles will spray the nutrient solution to the plant roots at short intervals. This regular spray has benefits of keeping the roots moist and supply the nutrients they have .

The growing chambers should be airtight and lightweight proof (to prevent the basis zone being penetrated by lights and make algae cannot thrive). It must allow air to urge certain the expansion of plant roots but you furthermore may don’t want pests to urge in or water to spill over . The chamber must be ready to hold within the humidity also . the last word factor which creates a successful aeroponic system may be a balance of many moisture, nutrients and fresh oxygen that you simply can provide to the roots.

Finally, a serious factor which contributes to the success of this technique is that the water droplet size. A the fine mist would makes much quickly to growing and bushier roots. These roots even have more area to soak up the oxygen and nutrients compared to those sprayed with small streams of water from small mist nozzles. this may also mean faster-growing plant canopy.

Some of the key benefits of aeroponics:

  • Efficient plant growth:The chief feature of aeroponics. Plants grow fast because their roots have access to tons of oxygen 24/7.

  • Easy system maintenance: In aeroponics, all you would like to take care of is that the root chamber (the container housing the roots) which needs regular disinfecting, and periodically, the reservoir and irrigation channels. The constant semi-moist environment of the basis chamber which invites bacterial growth is that the only main drawback of all aeroponic system maintenance.

  • Less need for nutrients and water: Aeroponic plants need less nutrients and water on the average , because the nutrient absorption rate is higher, and plants usually answer aeroponic systems by growing even more roots.

  • Mobility: Plants, even whole nurseries, are often moved around without an excessive amount of effort, as all that's required is moving the plants from one collar to a different .

  • Requires little space: You don’t need much space to start out an aeroponics garden. counting on the system, plants are often stacked up one on top of every other. Aeroponics is essentially a modular system, which is ideal for maxing out limited space.

  • Great educational value: you'll learn an excellent deal about plants from aeroponics. Kids especially will love having alittle aeroponic system to grow a pet plant, without having to urge their hands dirty.

Key disadvantages of aeroponics

  • Dependence on the system – A typical aeroponics system is formed from high pumps, sprinklers and timers. If any of those break down, your plants are often damaged or killed easily.

  • Technical knowledge required – you would like a particular level of competency in running an aeroponic system. Knowledge of nutrients amounts required by your plant is important , because you don’t have any soil to soak up excess/wrong nutrients supplied.

  • Regular cleaning of the basis chamber – the basis chamber must not be contaminated, alternatively diseases may strike the roots. So you would like to disinfect the basis chamber every so often. peroxide is usually used as disinfectant.

  • High cost – Most aeroponic systems aren't exactly cheap. Aeroponic systems may cost many many dollars each. the foremost affordable one I noticed, remains the one by AeroGrow, a singular sort of commercial aeroponics. Edit – Some folks means that AeroGrow isn't aeroponics – i feel it's still an excellent system for little premises.


In conclusion, the simplest advantage of aeroponics are the efficient plant’s growth and better yields with compared to other systems. However, these advantages also accompany a price . the worth to line up the system quite "> is sort of expensive and it also requires technical expertise also as advanced knowledge (about pH and nutrient density ratio) for this special kind of plant cultivation. If you're a beginner within the domain of growing hydroponically, i might say really weigh the pros and cons and choose the simplest system that you simply think will work for you at this stage.
