Best Aeroponic Tower Garden Buyer’s Guide: From A to Z
Let’s start with a quick FAQ section to make sure you know something about aeroponics. Then, we’ll get into more detail on the systems, how they work, how to choose a proper one, etc.
FAQ on Aeroponic Tower Gardens
Aeroponics is a soil-free method of growing plants. It involves placing seedlings in a very humid microclimate. This is a newer, easier way to do hydroponics which has been around for ages. The method requires minimum effort and provides amazing results.
How does it work?
Here are the basics of aeroponics:
- You don’t put seedlings in any growing medium;
- There are collars that support the stem, while the roots are hanging in the air with enough space to grow further;
- The whole construction is placed upon a reservoir with water and all necessary nutrients;
- The roots get more oxygen and grow faster because they are just hanging in the air;
- Special sprays are installed between the water tank and the roots; they spray the mix right on the roots;
- Most structures have a timer of sprays, so you don’t have to do much manually.
What can I grow using aeroponics?
Basically, you can grow anything there. But it’s important to remember that every plant is different and has precise needs for nutrients. Besides, some don’t like when it’s too humid around. Consider that before choosing what to grow.
Here are some examples:
- Seedlings - they are very tender and smooth, non-contact hydration helps them develop faster;
- Herbs - the most thriving type because herbs don’t take much time to grow and they don’t need too many nutrients;
- Vegetables - especially green like lettuce, cucumber, kale, etc.;
- Fruit - the most popular are watermelon, strawberry, pear, plum, etc.;
- Flowers - roses, carnation, orchids, and other annual flowers will feel great in an aeroponic tower system.
Types of Aeroponics Growing Systems
There are three main types of aeroponics:
- Low-pressure aeroponics;
- High-pressure aeroponics;
- Ultrasonic fogger aeroponics.
Now, these terms might seem very difficult, but let’s talk about each type in more detail.
Low-Pressure Aeroponics (LPA)
This one is the best pick for a newcomer. It’s very easy to use and only needs sprinkles, a water tank for nutrient mix, a platform, a tower to place plants in, and a pump. The drops it creates are like a hair in diameter (50 microns).
This is also a universal type, so you can grow anything there. It’s not difficult to install or maintain either. Most stores sell these systems, and the prices are very reasonable.
|Affordability;||Not suitable for large-scale growing or plants that require a large number of nutrients.|
|Easy to set up, maintain, and grow plants in.|
High-Pressure Aeroponics (HPA)
This is a good option if you need smaller droplets than 50 microns. This size creates an environment where roots get even more oxygen. Nutrients are delivered and distributed faster and the plants grow at a new speed.
The technical difference between these systems includes specialized sprinkles and a very powerful pump. The units are more difficult to set up than LPA ones. However, this is the most common choice for commercial aeroponics.
|Brings more oxygen to the roots;||More difficult to install and maintain;|
|Better nutrient delivery.||More expensive.|
Ultrasonic Fogger Aeroponics (Fogponics)
This system can atomize water to less than 5 microns per droplet. You can’t see the sprinkling process, it’s like light fog. Actually, people can’t physically see it because the droplets are smaller than our red blood cells.
Such a unit is suitable for very sensitive, small plants that require the lightest application of water and nutrients to grow. Fogponics works best for growing seedlings and herbs. This system is quite difficult to set up and costs much more.
|The best water and nutrient delivery to the plants;||Quite expensive to buy, install, and maintain properly;|
|Suitable for the most sensitive plants.||Frequent cleaning required to make sure salt doesn’t build up and block the sprinklers;|
|In case of a power outage, requires a lot of maintenance.|
Aeroponics Vs. Hydroponics
Aeroponics is evolved hydroponics, basically. But there are some differences you should know:
Hydroponics DWC system example on the image.
Aeroponics leaves the roots of plants in the air for better oxygen intake. There are net pots, towers, and other structures that achieve the goal. Hydroponics work only if you submerge a part in the water and nutrient mix.
Aeroponics creates a humid environment. The delivery of nutrients and water is done through the sprinkling of the roots. Hydroponics requires the roots to be submerged in water or put in a growing medium, creating a wet environment.
Aeroponics doesn’t require lots of actions from you, but sprinkling may lead to different levels of pH and nutrients in the water every time. It’s not too bad, but some plants won’t like it. Hydroponics offers steady levels, but the water requirements are much higher. So, you should choose the one that fits your purpose of water-saving and plant type.
4. Speed of growth.
Usually, aeroponics offers a faster growth rate due to constant exposure of the roots to oxygen. Hydroponics still offer amazing results, but the plants grow a little slower.
Aeroponics have much shorter cycles because they have to mist the roots and not let them dry out. If the timer of sprinkling fails, it will be a disaster for the plants unless you notice it right away. Hydroponics have longer, steadier cycles, and mistakes can be managed better.
Overall, aeroponics is easier and more energy and water-efficient method. Hydroponics, on the other hand, works better with plants sensitive to nutrient fluctuations.
When choosing a system, you have to consider a wide range of factors. From the type of system you want to the plants you’ll choose and the budget, everything is important. The best recommendation here is to always make an informed decision. Gather all the data on the model that you like and investigate.
Read reviews, experiences of people who grew something using the model. Consider the kind of plants and their needs, whether you want to grow inside or outside, etc. All in all, aeroponics is an incredible way to grow your own food with minimal effort. And if the system is high-quality and easy to maintain, you’ll definitely achieve results!
