What You Can Grow Using An Aquaponics System

Using an aquaponics fish tank provides a great way to grow fruit and vegetables in your own home. Aquaponics is the process of combining fish farming and plant cultivation in a recirculating system. It is an eco-friendly method that has been used for many years by ancient cultures all over the world. Still, it has only recently been introduced to modern society as a sustainable solution for food production.

Aquaponics systems use recirculating water containing plant nutrients and organic matter from the fish tank – resulting in a self-sustaining ecosystem of life. Fish excrete ammonia, which can be toxic to aquaponics plants, so it needs to be converted into nitrites first before being used as fertilizer for plants. The plants then use nitrates as nutrients. This blog post will review what you can grow using an aquaponics system and other features that make this gardening efficient.

Plants You Can Grow In An Aquaponics Fish Tank

In an aquaponics fish tank, you can grow a variety of plants. Plants grown through hydroponic methods are likely to be more profitable than fish originating from recirculating aquaculture systems as they require less space and energy inputs for cultivation.


Lettuce is a popular and easiest plant to grow in an aquaponics fish tank because they require little maintenance and produce a high market demand for their product. They have short growing cycles, making them ideal for people just starting with this type of farming. 

Lettuces love sunlight, so position them to receive five hours of it per day from either natural or artificial light sources (if the system is stationed indoors). Otherwise, locate it near plenty of open space that receives direct exposure to sun rays.


Basil is one of the robust plants that can grow in your backyard or water-based aquaponics fish tank. Basil plants are tolerant of hot and wet climates, making them perfect for an outdoor farm with lots of sun exposure, so you have the best harvest possible. The basil leaves will need 6 to 8 hours of sunlight each day for optimal growth.

If the basil aquaponics plants do not receive enough light, their production may decrease noticeably after just one week due to a lack of chlorophyll energy conversion from photosynthesis.

Cabbage is a hearty aquaponics plant that loves the sun and does quite nicely in shadier locations with adequate water. Plant your cabbage two feet apart from each other to provide enough space for them to grow tall without overcrowding one another or using up too many liquid resources unnecessarily. 

You can expect these aquaponics plants to mature between 70 days – 100 days, depending on how you take care of them. However, if they are left unattended long enough, they may start producing earlier than expected. Cabbage has many uses, so make sure not all go into salads; it works great when mixed with wine vinegar salad dressing because of its flavour.


Cucumbers are hard to contain with their extensive root systems, but they offer many benefits. For example, cucumbers can help repopulate nitrogen in your aquaponics fish tank and reduce the need for additional fertilizers or pest control products.

They also provide an excellent yield per square foot, making them worth growing if you have limited space available, especially when considering multiple seasons. However, there is one more thing to watch out for. Cucumber plants tend not only to take up water from pipes and siphons but also invade these spaces, leading to blockages further down the line. So be mindful of this fact before planting too close on all sides.

Strawberries are a perfect plant to grow in your aquaponics fish tank. Due to the constant supply of nutrient-rich water and the ability to control their environment, plants don’t need to know that it is winter, and you can harvest them all year round.

To raise strawberries in an aquaponics system, make sure there are many plants available for production because each one will only produce a few berries. If you want to eat or sell them, you must have enough, so they bear fruit well. The good news is that each strawberry needs very little space, which makes growing lots easy on any size farm.

In addition to the above plants, there are several others you can grow, depending on your location and preference. Also, if you like, you can rear fish in an aquaponics fish tank.

Fish You Can Grow In An Aquaponics Fish Tank

You can grow a variety of fish in an aquaponics system. A few of them are described below.


Tilapia is a resilient, tasty fish that can survive in most environments. It is incredibly hardy and adapts easily when introduced into new habitats, making it an ideal candidate for an aquaponics fish tank

Tilapia thrive best at temperatures around 82°-86°F with low pH levels between 6.5-9. So you may need to regulate its environment accordingly depending on your needs or those of other animals living near them (such as frogs). Tilapia fish can be harvested between six and eight months, depending on the size you want. You can harvest them when they reach approximately one pound in weight for best results.

Murray Cod

The Murray Cod is a great choice for people looking to stock their tank with high densities of perch. This aquaponics fish has the added benefit that it will grow fast, even in an enclosed environment like this. It is worth noting that you are required to feed this fish well and satisfy its appetite, or else hunger might take control over your aquarium, which can lead them to attack one another.

Rear these aquatic pets if you have time on your hands because they will require more maintenance than other types. If you want to grow your Murray cod, there are a few necessary steps. First and foremost is the water temperature, which needs to be between 46°F-75°F with a pH of 7-8. But once cared for properly these fish could live up to 20 years old.

The Catfish is the perfect aquaponics fish tank because it can easily adapt to new conditions. In fact, they will grow quickly and are comfortable with water temperatures of 75-86°F. This implies that you won’t have to keep changing your equipment so often due to the different temperature requirements of other types of fish like salmon or trout.

Catfishes make great additions to any aquaponics setup, including ones explicitly used as home installations, such as those made from recycled materials right on your kitchen countertop (or wherever else you might need one). You will also find out why people love them when one pound catfish could be ready for consumption in 18 months.


In case you are not planning to eat fish from your aquaponics fish tank, ornamental goldfish make a great option. They can survive in water with high pollution levels and come in two varieties: single tail or twin tails. Single-tailed goldfish tend to be faster than their twin-tailed cousins, but both types provide an attractive alternative for people who would rather avoid eating the food they grow themselves.

Goldfish are one of the hardiest species in existence. At most, they grow to a pound within 12 months and can get up to be one foot long. However, that doesn’t concern people using them as pets since goldfish generally aren’t harvested for food.

Crappie is a fish that can be found in freshwater and saltwater. They are part of the sunfish family but have two subspecies: black crappies and white crappies. Black Crapps usually grow to between 5”-19” long and weigh ½ – 1 pound on average depending on size, with their bodies are darker than whites who range from 6 7″–20 9″.

White craps also vary in weight at around ¼ lb.-1lb. Both grow across similar lengths (6 7″- 20 9″). Both are hardy and can tolerate temperatures between 55°F to 80°F. The best pH level lies between 6.5 – 8.2 so that their skin doesn’t start peeling off. It takes about two years before these aquaponics fish reach a harvesting size of 1 pound.

What Else Can You Grow In An Aquaponics Fish Tank?

Apart from aquaponics fish and aquaponics plants, you can grow prawns and shrimp in an aquaponics fish tank. These small crustaceans are the world’s most popular seafood, and their demand has been steadily growing.

They are part of the shrimp family. It may or may not be your number one choice when building an aquaponics fish tank. But it should be one that you consider since prawns provide nutrition for plants and food for people.

They can tolerate a pH range of 6.5-8 but are not good at coping with temperature changes. You must ensure you have this sorted before the shrimp and prawns arrive in your aquaponics fish tank. Remember, once they are delivered, their harvesting may take several months.

To Summarise

The Aquaponics system is an excellent option for those interested in starting an indoor garden to grow their food. It can be an extremely rewarding event to watch your plants and fish grow. This blog post has provided all the information you might need about what you can grow in an aquaponics fish tank and how. It should help you make informed decisions when designing or purchasing one of these systems for yourself.
