How To Build A High Pressure Aeroponics System – The Most Specific Guide!

“How to build a high pressure aeroponics system” is the most frequently asked question we have received from several garden lovers. Of course, learning how this system functions as well as how to get it done can be a stubborn challenge for non-experienced users. 

Understanding your concern, we are here and willing to share with you some legit tips for building a high pressure aeroponics system. Scroll down to find out more. 

What Is A High Pressure Aeroponics System? 

A high pressure aeroponics system, HPA for short, is a kind of aeroponic growing network. 

This system allows plants to grow with their roots suspended midair instead of being planted in soil. And the roots are provided with necessary nutrients in the form of mist 

To be more specific, the HPA system generates a high pressure of around 120 PSI to deliver the mist to the plant’s roots, which results in  an improvement in plant growth. 

Hence, this is considered a prevalent and useful method in the agriculture industry that gains massive support from thousands of DIYers all over the world. 

Benefits And Drawbacks 


It must be mentioned that water use efficiency is the primary benefit of the high pressure aeroponics system. Compared to other conventional plant growing methods, this one is capable of saving a large amount of water. 

What is more, this method only takes 1/3 of nutrients consumption that you use for the soil and hydroponic growing methods. Don’t get wrong that your plants will be underdeveloped as they cannot absorb enough nutrients. Rest assured that the growth is still guaranteed.

At the same time, this out-of-the-box method creates a chance for you to increase the production of crops without land occupancy. Above all, this is a friendly system that does wonders for not only your plants but also your wallet – you can cut down on all your soil expenses!


Despite those above-mentioned benefits, the HPA system shows some minor downfalls that we are going to take a deeper dive into. 

In fact, you will need to invest in more pieces or parts for assembly than other growing systems. Besides, a high pressure aeroponics pump plays a crucial role in making this method more effective. 

As a result, it seems that you cannot save much money when applying this system for agriculture.

Most notably, the HPA system needs cautious supervision and even frequent preservation to avoid clogged spray heads because of salt buildup. 

And we have to emphasize that this system depends totally on electricity for a normal operation. Don’t let any failure happen, or else all your efforts will be gone up in a puff of smoke. 

How To Build A High Pressure Aeroponics System On Your Own? 

To build a perfect high pressure aeroponics system, there are some tools and primary components that you should take into account.

High Pressure Pump

A high pressure pump is undeniably the primary component contributing significantly to the successful HPA system. 

In particular, a water pump must be able to supply enough droplet size in a range of 20 to 50 microns. Generally, it often comes to the market with two types, which are the diaphragm and reverse osmosis booster pumps.

In order to deliver a steady 80PSI production for your system, it is highly recommended to pick a product that can generate 100PSI or even more. You will find it somewhat challenging to make any adjustments later, so let’s give priority to a pump set for 80 to 100PSI at first. 

Accumulator Tank

The accumulator tank works as a supporter to maintain the right water pressure in the pipes so that your pump cannot overwork. 

Usually, these accumulator tanks are pre-pressurized and divided into two spaces. One space has a rubber bladder, which expands and narrows force and water. The other is taken by the pressurized air, aiming at pushing water out of the faucet. 

Hence, these tanks work well in extending the lifetime as well as reducing the demanding usage of the pump. As a result, you can save a lot of money indeed.

On top of that, this component also serves another useful purpose. Specifically, it helps to create the right size droplets for your garden by generating constant pressure whenever the solenoid is opened. 

Without an accumulator tank in an HPA system, the size of the droplets can be bigger than it is supposed to be. As such, less oxygen will be provided to the root  

Electrical Solenoid

Furthermore, an electrical solenoid is considered a valve that is electronically operated shut-off to start and discontinue the water flow to the system when the timer turns off and on. 

Plugged into a relay timer circuit, this solenoid is quite similar to an automatic lawn sprinkler system. The best timers for running the solenoid must be installed to be precise to one second on and in the minutes off. 

Pressure Switch

The pressure switch’s sole use is to control the pressure to the whole system by showing at what pressure the pump is supposed to turn on and off. Sounds simple, right?

For example, it turns the pump off whenever this switch measures the right pressure of 100PSI, on the contrary, the pump will be turned on at 80PSI pressure. 

Some pumps typically include this component as a set, or it can be purchased separately. 

Misting Nozzles

Last but not least, another extremely vital factor in making your best aerogarden is the misting nozzles. You will have to pump the water through some small vents at high pressure so that the atomization can be achieved. 

The smaller nozzles are the most optimal choice that saves on your nutrients as well as the cost of operation. Prior to misting nozzles, you had better utilize a fine mesh filter to prevent clogging. Large nozzles will cut down on the clogging situation, but it is not truly necessary and good enough in this case.

Wrapping Up 

This is a wrap up of our guide on how to build a high pressure aeroponics system without any hassle. You might feel overwhelmed to grasp all the things at first, but this instruction is written for the purpose of assisting you in dealing with this agriculture project effortlessly. 

We do hope that you can understand the importance of this HPA system for your garden as well as learn the right way to grow fast and healthy plants.
