Whether you have a sprawling backyard or just a tiny balcony, aquaponics offers an opportunity to grow a diverse array of produce while protecting the environment.

This aquaponics for beginner's guide will discuss the basics of aquaponics, from learning the different components to walking you through the steps of setting up your own thriving aquaponic garden.

Understanding Aquaponics

Aquaponics is a method of growing food that combines aquaculture (the practice of raising fish) and hydroponic (a soilless way of growing plants). Through the combination of these two growing methods, aquaponics offers a way to grow food that is resource-efficient, environmentally friendly, and yields high-quality produce.

How Does Aquaponics Work?

In aquaponics, the waste produced by fish is converted by the beneficial bacteria into nutrients that plants absorb. The plants, in turn, filter the water for the fish. This creates a closed-loop system that uses 90% less water than traditional agriculture and can produce fish and vegetables in a small space all year round.

Aquaponics relies on a mutually beneficial relationship between fish and plants. Which involves fish excreting waste that is broken down into vital nutrients that plants use for nourishment. In return, plants act as natural filters that purify the water and allow the fish to thrive in a clean and healthy environment.

 

The Aquaponics General Cycle

The Benefits of Aquaponics

Here are some benefits of aquaponics.

  1. Sustainability: Aquaponics uses less water than traditional growing methods and doesn't rely on harmful chemicals or pesticides to produce fresh and healthy fish harvests, fruits, herbs, and vegetables. 
  2. High Yield: Aquaponics can produce a high yield of fish and plants in a small space all year round (if done in an indoor setup). Plants grow faster in aquaponics systems because of their constant access to nutrient-rich water. 
  3. Fresh, Nutritious Produce: Aquaponic systems can grow a variety of fresh produce that is high in nutrients and free from harmful chemicals. Because the plants grown in aquaponics are free from fertilizers and other chemicals. 
  4. Water Conservation: Aquaponics is an eco-friendly method of growing food. It uses up to 90% less water than traditional agriculture because the water is recycled through the system.
  5. Reduced Chemical Usage: In the aquaponic realm, fish waste and beneficial bacteria become the nutritional backbone of plant growth. It's a natural cycle that sidesteps the need for harmful chemicals or fertilizers.
  6. Year-Round Gardening: Aquaponics allows you to cultivate produce all year, regardless of weather conditions. This uninterrupted growing season means a constant supply of fresh, homegrown goodness.
  7. Space Efficiency: Aquaponics become your gardening solution if space is a problem. Its vertical growing potential and compact footprint make it a space-efficient marvel. You can stack layers of growth, maximizing yield in even the tiniest of spaces.
  8. Cost Savings: Aquaponics cuts down on ongoing costs by eliminating the need for traditional fertilizers and minimizing water usage. Plus, the potential for a consistent harvest means fewer trips to the grocery store.
  9. Sustainable Food Production: In a world striving for sustainable food sources, aquaponics reduces the strain on conventional agriculture, conserve resources, and foster a harmonious coexistence between food production and the environment.

Things to Consider Before Starting an Aquaponics System

Here are some important factors to consider in planning your aquaponics system. 

1. Personal Considerations

Choose an aquaponics system that you want to implement. You can choose between media-based systems, raft systems, NFT systems, or a combination of these systems.

  • What are the goals and purpose of your aquaponics system?

What is the purpose of your aquaponics system? What plants or fish are you planning to grow and raise? Are you going to eat your fish? These questions should be given thought to plan your system correctly and know what method will meet your goals and purposes.

  • Do you like to do-it-yourself (DIY)?

Do you like assembling things through (do-it-yourself)DIY, or do you prefer to purchase a ready-to-use free-made system? DIYing your own system or buying a free-made ready-to-set-up aquaponics system is one of the essential considerations you need to make in planning your aquaponics system.

DIY Aquaponics is trial and error but it can be a rewarding and fun learning experience. However, if you want a proven system that can run quickly and with technical support, you can purchase a free-made aquaponics system.

2. Environmental Considerations

A. Humidity: In an aquaponics system, the water flow is constant, so you must consider your space's natural evaporation and increased moisture. 

B. Water Spillage: Your fish tank or aquarium can leak. Therefore, the area where you want to create your system is an area that can get wet.

C. Lighting: Plants need light to grow. All plants require sunlight for photosynthesis, which converts light, oxygen, and water into carbohydrates (energy). Plants need this energy to produce, bear fruit, and bloom. 

Sunlight is the best source of light for plants in an aquaponics system. But with an indoor aquaponics system, you need to use grow lights to supplement the light requirements of your plants. Artificial lighting needs to be considered and carefully selected because plants absorb wavelengths at either end of the light spectrum, which we cannot see.

3. Location and Space Considerations

Here are some key considerations when choosing a location for your aquaponic system.

  • Access to natural light: Plants require enough light to grow, so choose a location where natural light or sunshine is accessible. 

  • Temperature: Choose a location where the temperature can easily be regulated. Consider installing a heater or air conditioner to maintain a consistent temperature.

  • Water source and drainage: Your aquaponic system will require a constant water supply, so choose a location near a reliable water source. Also, ensure that your location has adequate drainage to prevent water from accumulating around the system.

  • Electrical outlet: Your aquaponic system will require an electrical outlet to power the water and air pumps. So choose a location near an outlet or consider using an extension cord to reach a nearby outlet.

  • Ventilation: Proper ventilation is vital to prevent the buildup of humidity and to ensure that there is adequate airflow for the plants and fish.

Types of Aquaponics Systems

The main types of aquaponic systems are media-based, raft systems, nutrient film techniques, and hybrid systems. Each one of these system has its own advantages and disadvantages, so choosing the one that best fits your needs and space requirements is essential.

1. Media Based Aquaponics System

The media-based system is the most popular type of aquaponics system. In this system, plants are grown in a medium, such as gravel or expanded clay pellets, that provide a surface for beneficial bacteria to break down fish waste and turn it into nutrients. The water is then returned to the fish tank.

2. Raft System

Also known as the Deep Water Culture (DWC), the raft system of aquaponics is one of the most efficient aquaponics system designs. This system is often used in large-scale or aquaponic farming systems because of its mass production capability. 

In this system, the plants are suspended in rafts on top of the water in the fish tank. The roots of the plants dangle in the water, and the beneficial bacteria break down the fish waste, providing nutrients for the plants.

3. Nutrient Film Technique (NFT) System

The Nutrient Film Technique (NFT) is a hydroponic growing technique adapted to aquaponics because of its simple yet effective design that works well in some environments. This method uses horizontal pipes (PVC) with shallow streams of nutrient-rich water flowing through them. The NFT is famous for commercial aquaponics and is also helpful in urban places where space and food production are problems.

      Lots of great info in the article.

      I bought some fresh cilantro the other day with a robust root system. Felt it was a waste to throw it out so I planted one stem in my tank (small gravel substrate). And punched a few holes in a new sponge I had, and am floating 3 more stems on the top.

      I have 1 Bala shark, 1 red tail shark, 1 ruby barbs, 2 red sword tails and 1 pleco in a 55 gallon tank. I have other live plants submerged as well.

      Any concerns with the set up? I see the proper way is not to have the roots in the water with the fish.
