The Different Types of Aquaponics Grow Beds

Over the past 2000 years or so, agriculture (and most notably farming), has benefited greatly from technological advancements, with aquaponics being one of the most recent innovative breakthroughs.

This may seem familiar to people who are interested in farming and learning about new agricultural technologies but for those of you who are hearing this for the first time, this whole process might seem strange and unfamiliar.

Aquaponics is the most recent breakthrough in farming, in which plants and fish have a symbiotic relationship. It occurs when fish excrement permits plants to thrive in this type of environment, and fishes feed on the waste of the plants.

Aquaponics has piqued the interest of many people. It enables the dedicated farmer to have their own aquaponics system in their home, apartment or garden, whether they have a large or small space. They can also produce a relatively high yield without the use of synthetic ingredients. Many people are embracing this new type of gardening for a variety of reasons. However, there are many questions about one particular aspect of building an aquaponics system, the grow-bed. Although it’s a vital part of any good aquaponics system, there seems to be a bit of confusion surrounding what it is, how to set it up, and what kind to install, so, today, in this post, I’m going to try and answer some of the more frequent questions I get asked.

The grow bed is one of the most important parts of an aquaponics system because it is where the plants are grown.

Nutrient Film System

The Nutrient Film Technique is a method of applying nutrients to a surface.

NTF is another name for this sort of grow bed. In this form, nutrient-rich water is poured through gutters so that plant roots can come into contact with it. Because there is a very thin film of nutrient-rich water in this sort of grow bed, it is known as NTF. Plastic cups are required for the plants in this design. However, because it has limits, this method is the best option for everyone. Because it is predicted that the minerals in the water will clog up the entire system, the correct plant must be used for this system, as well as excellent maintenance. If this isn’t working, move on to the next sort of system.

The Media-Saturated Bed

A growing media is required in this type of grow bed. It could be perlite, gravel, or something else entirely. This media replaces the filtration method employed in other varieties. For example, you’re working with gravel as your medium. As a result, the gravel filters the water for the benefit of both the plants and the fish. Furthermore, this form of grow bed does not necessitate a continual water supply. You only need to be certain of the media you’ll employ. Other minerals may be exposed to the gravel, which might be hazardous to the aquaponics system. Always wash them before placing them in the aquaponics to be sure.

The System of Rafting

All commercial growers should choose this type of aquaponics grow bed. This is owing to their ability to produce a good harvest. The roots of the plants can touch the water in this method, while the plant’s body and leaves remain dry on the upper half of the raft. The plants and fishes will then come into contact. The plants’ raft is usually made of Styrofoam to guarantee buoyancy.

Now is the time to pick the appropriate grow bed for your aquaponics system. You are the one who has to make this decision.
