Hydroponics vs Aquaponics: Methods
Hydroponics and aquaponics are two methods of soil-less gardening that use aquatic solutions and fish to provide nutrients and water to plants. However, they differ in how they are designed and what components they use. In this section, we will compare and contrast the basic elements of each system, such as the water reservoir, the growing medium, the pump, the filter, the fish tank, etc. We will also use diagrams or images to illustrate the differences.
Water Reservoir
The water reservoir is the container that holds the nutrient solution or the water for the system. In hydroponics, the water reservoir is usually separate from the plant growing area, and the nutrient solution is added manually or automatically to the water. The water reservoir can be made of plastic, metal, or other materials, and it can have various shapes and sizes, depending on the system design and the space available. The water reservoir should be dark or covered to prevent algae growth and evaporation.
In aquaponics, the water reservoir is usually the same as the fish tank, and the nutrient solution is produced by the fish waste. The water reservoir can also be made of different materials, but it should be large enough to accommodate the fish and provide adequate oxygen and water quality. The water reservoir should also have a lid or a cover to prevent fish from jumping out and to reduce water loss.
Growing Medium
The growing medium is the material that supports the plant roots and provides aeration and drainage. In hydroponics, the growing medium can be inert or organic, and it can have various textures and properties. Some common examples of hydroponic growing media are rockwool, perlite, vermiculite, coco coir, clay pebbles, gravel, sand, etc. The growing medium should be sterile, lightweight, porous, and pH-neutral.
In aquaponics, the growing medium can be similar to hydroponics, but it should also be suitable for the bacteria that convert the fish waste into plant nutrients. Some common examples of aquaponic growing media are expanded clay, lava rock, gravel, etc. The growing medium should also be inert, durable, and easy to clean.
Pump
The pump is the device that moves the water or the nutrient solution from the reservoir to the plant growing area and back. In hydroponics, the pump can be submersible or external, and it can have various capacities and flow rates, depending on the system design and the water volume. The pump should be powerful enough to deliver the nutrient solution to the plants at the desired frequency and duration, and it should be reliable and energy-efficient.
In aquaponics, the pump can also be submersible or external, and it can have similar characteristics as hydroponics, but it should also be compatible with the fish and the bacteria. The pump should not harm the fish or disturb the biofilter, and it should be able to handle the solids and the organic matter in the water.
Filter
The filter is the component that removes the solids and the organic matter from the water or the nutrient solution. In hydroponics, the filter is usually optional, as the nutrient solution is relatively clean and free of debris. However, some hydroponic systems may use a filter to prevent clogging of the pipes or the drippers, or to improve the water quality. The filter can be mechanical, biological, or chemical, and it can have various types and sizes, depending on the system design and the water volume.
In aquaponics, the filter is essential, as the water is rich in fish waste and organic matter. The filter serves two main functions: to remove the solids and to provide a surface for the bacteria to grow. The filter can be divided into two stages: the mechanical filter and the biofilter. The mechanical filter can be a screen, a swirl, a clarifier, or a settler, and it can remove the large particles and the suspended solids from the water. The biofilter can be a media bed, a trickling filter, a moving bed, or a fluidized bed, and it can host the bacteria that convert the ammonia and the nitrite into nitrate. The filter should be efficient, easy to maintain, and well-aerated.
Fish Tank
The fish tank is the component that houses the fish and provides the water for the system. In hydroponics, the fish tank is not present, as the system does not involve fish or other aquatic animals. In aquaponics, the fish tank is one of the most important components, as the fish are the source of the nutrients and the income for the system. The fish tank can be made of various materials, such as plastic, fiberglass, metal, or concrete, and it can have various shapes and sizes, depending on the system design and the fish species. The fish tank should be large enough to accommodate the fish and provide adequate oxygen and water quality. The fish tank should also have a heater, an aerator, a thermometer, and a pH meter to control the temperature, the dissolved oxygen, the pH, and other water parameters.
Hydroponics Vs aquaponics: Commercials
Hydroponics and aquaponics are two methods of soilless gardening that use aquatic solutions and fish to provide nutrients and water to plants. However, they differ in how much they cost and how much effort and skill they require to operate and maintain. In this section, we will compare and contrast the initial and ongoing expenses of each system, such as the equipment, the nutrients, the fish, the electricity, the water, etc. We will also discuss the level of effort and skill required to operate and maintain each system.
Initial Costs
Hydroponics systems are generally cheaper and simpler to set up than aquaponics systems. They don’t require as many components, and the cost of the nutrient solution is typically less than the cost of purchasing and caring for aquatic animals. According to one source1, the average cost of setting up a hydroponics system is around $500, while the average cost of setting up an aquaponics system is around $1,000. However, these costs may vary depending on the size, type, and quality of the system and the materials used.
Aquaponics systems require extra components, such as filtration, aeration, and fish tanks, which add to the initial cost. They also require buying and stocking fish, which can be expensive and challenging, depending on the availability and legality of the fish species. Additionally, aquaponics systems require a longer acclimation or cycling period, which can take 6 to 8 weeks, before they can reach full productivity. This means that the return on investment may take longer for aquaponics than for hydroponics.
Ongoing Costs
Hydroponics systems have lower ongoing costs than aquaponics systems, but they also have lower potential profits. The main ongoing costs for hydroponics systems are the nutrient solution, the electricity, and the water. The nutrient solution has to be carefully managed and replenished, as it can lose its effectiveness over time or become contaminated. The electricity cost depends on the type and size of the pump, the lighting, and the heating or cooling system. The water cost depends on the water source, the quality, and the frequency of replenishment.
Aquaponics systems have higher ongoing costs than hydroponics systems, but they also have higher potential profits. The main ongoing costs for aquaponics systems are the fish food, the electricity, and the water. The fish food is the primary source of nutrients for the plants, and it has to be of high quality and quantity to ensure the health and growth of the fish and the plants. The electricity cost is similar to hydroponics, but it may be slightly higher due to the need for additional air pumps. The water cost is lower than hydroponics, as aquaponics systems recycle water between the fish tanks and the plant beds, and they don’t require flushing.
Effort and Skill
Hydroponics systems require more effort and skill than aquaponics systems to operate and maintain. They require daily monitoring and testing of the nutrient solution, the pH, the EC, and the temperature. They also require regular cleaning and maintenance of the equipment, the pipes, the drippers, and the growing medium. They may also require pest and disease control, as hydroponics systems are more prone to infections and infestations than aquaponics systems.
Aquaponics systems require less effort and skill than hydroponics systems to operate and maintain. They require weekly or biweekly monitoring and testing of the water quality, the ammonia, the nitrite, the nitrate, and the pH. They also require occasional cleaning and maintenance of the filters, the pumps, and the growing medium. They may also require fish health and welfare management, such as feeding, harvesting, and restocking. They are less likely to suffer from pests and diseases, as aquaponics systems have a natural balance of microorganisms and beneficial insects.
Commercial Applications of Aquaponics
