Aeroponics is an offshoot of hydroponics that focuses primarily on feeding the root zone via atomizers or misters.
Aeroponic systems do not rely on inert mediums, nor do they utilize a continuous flow of nutrient solution across the root zone.
Instead, aeroponic systems rely on short and frequent bursts of oxygenated water that are pushed through an atomizer.
The atomizers create an incredibly fine mist that spreads a nutrient-packed solution across the surface of the exposed root zone.
Furthermore, cannabis roots are held in suspension, where they have unlimited access to oxygen.
The constant exposure to air and the frequent bursts of nutrient solution create explosive growth, which is second-to-none in the world of cannabis cultivation.
Are Aeroponics Systems Expensive?
Aeroponic systems are considered the most expensive method when compared to other styles of growing cannabis.
The reason behind this is due to their precision, which consists of pumps, timers, pressure regulators, and atomizers.
Pre-built aeroponic units tend to be high-quality and utilize efficient parts. When it comes to growing cannabis in an aeroponic system, this is an absolute must.
The reason is that the root system needs to be exposed to the nutrient solution often.
If the root zone is allowed to dry, the damage will be potentially irreparable.
Although aeroponic systems are incredibly efficient, they do require patience and the ability to fine-tune the overall system before you grow your cannabis crop.
Due to the automation that surrounds an efficient aeroponic unit, prices are typically much higher than more familiar hydroponic units.
However, it’s possible to build your own aeroponic system cheaply. With the help of hardware found at a local hardware store, you can quickly and efficiently build your own aeroponic system.
The Benefit of More Oxygen in the Root Zone
The primary benefit of aeroponic systems is that they provide an abundance of oxygen to the root zone.
This is accomplished by the suspended root zone above the misters and the oxygenated nutrient solution via the atomizers.
However, it’s not just oxygen that fuels rapid growth, but also the increased exposure to CO2. Many indoor growers implement CO2 to facilitate faster growth and larger flowers.
Research shows that aeroponic systems provide an abundance of naturally-derived CO2 from the ambient air that’s consumed by a plant.
Additionally, more oxygen in the root zone has been researched to decrease the instance of pathogens that commonly attack cannabis roots.
Issues, such as root rot, are unlikely to become an issue because the root zone is never completely saturated.
Additional Benefits of Aeroponics
Aeroponic systems are at the forefront of cannabis cultivation because they offer a system that’s easy to keep clean.
The limited number of moving parts, lack of constant moisture, and the fact that inert mediums are not needed all create a sterile environment.
Aside from keeping things in the grow room clean, aeroponic systems also save cultivators a large amount of money.
This is because aeroponic systems don’t require a large number of nutrients or a continuous flow of water or energy powering a submerged pump.
The atomizer or mister releases such a fine spray that the nutrients become highly bioavailable to the root system.
In the case of aeroponics, less is more. It’s also a consideration to keep in mind if you find yourself giving a large serving of nutrients in other systems, such as hydroponics or soil.
Lastly, there’s no doubt that aeroponic systems are far less wasteful than typical hydroponic and soil-based growing systems.
If you’re eco-minded, then this aspect should be a significant consideration. Less water, electricity, and nutrients all help to decrease your carbon footprint, which is important to many currently.
Types of Aeroponic Systems for Cannabis Cultivation
Now that you have an idea of what aeroponic systems are and how they work let’s take a look at the different types that are available to beginners and commercial producers alike.
Low-Pressure Aeroponics Systems
Low-pressure aeroponic systems utilize low-pressure pumps. The root zone is suspended above the misters, which are fed by a reservoir that’s filled with nutrient solution.
This type of aeroponic system is considered a low-cost unit. The reason is that it foregoes water purification, filters, and does not have the penetrating power of their high-pressure counterparts.
When root zones become large, low-pressure systems have difficulty penetrating the entire root ball entirely. This leaves dry spots within the root zone, which leads to problems in the cannabis plant.
Although it’s problematic when the root zone isn’t thoroughly fed, the cost of low-pressure aeroponic systems is accessible for most.
High-Pressure Aeroponics Systems
High-Pressure aeroponic systems utilize a high-pressure atomizer that’s fed by a high-pressure pump. When it comes to root penetration – high-pressure aeroponic systems never miss their mark.
These types of systems are efficient by design and ensure a complete soaking of the root zone.
High-pressure aeroponic systems are very expensive because they also incorporate high-end accessories that ensure a pathogen-free crop.
Water purification, nutrient sterilization, and other high-value tools are used within high-pressure aeroponic systems to keep atomizers clean and roots healthy.
When it comes to aeroponics, it’s all about the roots. Although it’s always about the roots when growing cannabis (or any plant for that matter), aeroponics takes it to another level.
By focusing so much attention on the roots, cannabis plants thrive at an unimaginable rate.
Research has shown that plants that are grown via aeroponic systems experience rapid growth and larger yields.
When growing cannabis in an efficient aeroponic garden, your overall vegetation, and flowering cycles are likely to be reduced when compared to more traditional cultivation techniques.
Although aeroponic gardening is not as accessible as general hydroponics or soil-based methods, it offers cannabis growers with a new, efficient, and exciting way to produce our favorite herb.
