Aeroponics: The Definitive Guide to Get Started with Aeroponic Systems

Want to grow plants without worrying about soil quality? And save water in the process? Aeroponics could be just what you need.

Read on to find out more about this alternative to conventional agriculture and explore different aeroponic systems.

Aeroponics Definition

Aeroponics is the process of growing plants in a humid, misty environment without soil or another grow medium.

It’s a development of hydroponics that has been in use for decades. Technically, it’s more advanced than most hydroponics systems.

“Aeroponic” comes from Greek, from the words aer (air) and ponos (labor). It's is one of the least labor-intensive ways to grow plants, as you will see.

How Does an Aeroponic System Work?

An aeroponic system delivers nutrients straight to the roots of the plant. It doesn’t use any grow medium to keep the plant in place. Instead, the roots stay suspended in the air.

Sounds a bit strange? It's not at all! Here's are the basic principles explained.

  1. With aeroponics, you insert the plants into a platform with holes in it or net pots.
  2. Support collars hold the stems in place while leaving the roots enough room to grow.
  3. The platform sits on top of a reservoir with water and nutrients.
  4. Sprinklers connected to a water pump spray vapor over the roots at regular intervals.
  5. The vapor carries a precise amount of nutrients, water, and growth hormones.
  6. A timer regulates the spray intervals and their duration.
  7. The plant absorbs the nutrient spray and oxygen.

Good to know: Because the roots don’t sit in soil nor are they submerged in water, they get more oxygen than in a hydroponic system. The result? Better root oxygenation speeds up plant growth.

Aeroponics vs Hydroponics

Technically speaking, aeroponics is a type of hydroponics, which is why they’re often bunched together. But there are a few key differences between an aeroponic system and a hydroponic one. Discover them now.


Both systems use a pump and a reservoir and may also use a timer. That makes them look similar at a first glance.

But aeroponics secures the plants while leaving their roots exposed to the air. For this, it uses net pots or boards with slats or holes in them. In an aeroponics setup, the roots are never submerged.

Nutrient Delivery

With aeroponics, the roots of the plants grow in a nutrient-rich mist. A pump working on a timer mists the roots at regular intervals.

By contrast, in a hydroponic system, the roots stay in the water or another grow medium. Aeroponics creates a humid, fog-like growth environment rather than a wet one.

Efficiency of hydroponics systems

The mist flow of an aeroponic system can lead to fluctuating levels of nutrients and pH in the water. It's not a tragedy. But it does calls for more frequent testing than with a hydroponics system.

On the other hand, it requires less water to deliver nutrients to the plant. When properly set up, aeroponics is more water-efficient than hydroponics.

Also, because aeroponics exposes the plant to more oxygen, it promote faster growth.


Hydroponics systems have longer water and nutrient cycles. Aeroponics systems, on the other hand, mist the plants more often to prevent the roots from becoming dry.

This means that aeroponics needs to operate on a precise timer to enable healthy plant development. If the timer fails, well, that's bad!

So, what’s the bottom line in this comparison?

The Bottom Line: Aeroponic systems can be more energy-efficient than hydroponics but require more technical expertise. If they’re not properly calibrated, they don’t deliver.

Types of Aeroponics Systems

Aeroponic systems can operate at low or high pressure. This is what differentiates basic setups from advanced ones. Let’s take a closer look at the different setups you can use.

Low Pressure Aeroponics (LPA)

Most beginners start with a low pressure aeroponics system. This system uses a pump, sprinklers, a reservoir, and a platform for the plants with an enclosed root chamber.

This system creates water droplets over 50 microns in size. That’s about the diameter of a human hair.

LPA setups are relatively easy to install up and can handle most varieties of plants. You’ll find them in most hydroponic shops at good prices.

All things considered, LPA is a safe choice if you’re just getting started.


  • Easy to set up and use
  • Most affordable aeroponic system


  • For small scale use only
  • May not be powerful enough for plants requiring lots of nutrients

High Pressure Aeroponics (HPA)

High pressure aeroponics atomizes water below 50 microns. The very small droplet size creates more oxygen for the root zone. This improves nutrient delivery and speeds up plant growth.

HPA systems require a powerful pump and specialized sprinklers. What’s more, you have to set them up properly for them to work efficiently. Commercial aeroponics users usually opt for this system.


  • Improves root oxygenation
  • Delivers nutrients efficiently


  • Requires some technical knowledge
  • Can be expensive to set up

Ultrasonic Fogger Aeroponics (Fogponics)

Ultrasonic fogger aeroponics (fogponics) atomizes water below 5 microns so that they appear as fog. That’s way below the visibility threshold. It’s smaller even than a red blood cell.

Because they are so small, the droplets are less likely to hurt even young and sensitive roots. No surprise then that fogponics is great for seedlings, clonings, and herbs.

In theory, the smaller the droplets, the easier it is for the plants to absorb water. However, fogponics requires expensive equipment.

Also, it calls for careful maintenance to ensure the high-pressure pump operates optimally. Fogponics also requires more declogging.


  • Great coverage for the plant roots
  • Makes aeroponics cloning easy
  • High nutrient concentration


  • Buildup of salt requires constant cleaning
  • Atomizer can heat the reservoir
  • Susceptible to power outages

What Can You Grow with Aeroponics?

In theory, you can grow almost any plant. In practice, though, it’s important to remember that different plants have different nutrient requirements. Also, not all plants prefer growing in moist conditions.


Aeroponics is great for growing seedlings. Why? Because these have fragile roots that hydroponic or aquaponic systems may damage. Aeroponic systems mist the roots gently, causing no damage.


Clonings don’t have a developed root system. That makes it challenging to provide them with nutrients.


Cloning with aeroponics is easy because the small droplet size provides nourishment to the roots without damaging them.


Herbs grow faster than vegetables or flowers while usually requiring fewer nutrients. That means herbs thrive in aeroponics systems. The best herbs for aeroponics include basil, mint, and chives.


Aeroponics works best with green vegetables. But you can also grow other vegs. Here’s a list of vegetables you can grow:

  • Lettuce
  • Kale
  • Spinach
  • Cucumber
  • Eggplant
  • Tomato


Can you grow fruits aeroponically? Yes, you can. Here are some ideas:

  • Strawberries
  • Watermelon
  • Pear
  • Plum


As a general rule, you can use aeroponics to grow annual flowers but not perennials. That’s because perennials require beneficial bacteria and fungi only found in the soil.

  • Carnation
  • Roses
  • Orchid
  • Zonal geraniums

In the end, what you can grow with aeroponics depends on your setup, the nutrients you use, and how carefully you optimize your system.

The Best Aeroponics Systems

The quickest way to get started with aeroponics is to buy a ready-made system. LPA setups work with most plants and have low running costs.
