Most of us have heard of hydroponics but may not be familiar with the term “aquaponics”.

I know this is not something I know well, so I thought it would be a good idea to do some research and learn more about this interesting topic.

aquaponics is the combination of aquaculture and hydroponics where the waste products produced by marine animals such as fish, shrimp, snails and crayfish provide the nutrients needed to hydroponically grow plants.

Plants, in turn, purify the water to keep sea creatures alive.

While we normally associate things like lettuce and herbs with growing in this way, there are many different houseplants for aquaponics.

Aquaculture is the method of growing creatures such as snails, fish, shrimp, and crayfish in tanks while hydroponics is growing plants in water. Combine the two and we have aquaponics.

Literally, with aquaponics, we make fish work to eat and produce waste which in turn becomes the perfect fertilizer for plants growing in the water.

The plants keep the water cool and the cycle begins again.


What equipment do we use for Aquaponics?

Basically all you need is an aquarium, a water pump, fish and plants to get started.

Of course, the size of the tank will depend on the space you have, and the number of fish you can accommodate will depend on the size of the tank.

What plants can we grow this way?

a peace lilyAquaponics is particularly recognized for food production.

This method is often used to grow a lot of tomatoes and cucumbers, but it is also possible to grow other things like herbs, vegetables and flowers.

Even indoor plants can be successfully grown this way.

The success of growing plants using this method also depends on the maturity and density of the fish in your aquarium and the nutrient quality of the water.

Vegetables with low to medium nutritional requirements will grow well in aquariums with fewer fish. These include green leafy vegetables like cabbage, spinach, lettuce, herbs and chives.

The plants with the highest nutritional requirements are tomatoes, cucumbers and peppers. These need a denser concentration of fish to do well.

In fact, the list of vegetables that can be successfully grown this way is extensive! Shallots, red onions, peas, okra, cabbage, melons, strawberries… the list goes on.

Top 10 Indoor Plants for Aquaponics

1) Spider Plants

Because these plants thrive in moist soil, growing them in aquaponics is suitable for them.

Water has just the right amount of nutrients to get it right. The spider plant will even grow in the aquarium as long as only the roots are submerged.

It is very easy to propagate the plant this way by simply taking a cutting and placing it in the middle of the pot. You should see roots in about 7 days.

How does aquaponics work?

Aquaponics uses two breeding methods, namely growing plants without soil and raising fish.

The fish are fed and the waste is collected, they feed the plants that live in a medium other than the ground.

The plants get the nutrients they need from the fish water and the excess is pumped to the fish side of the plant.

So here is what happens:

  • Set up your aquarium with a pump to bring water from the aquarium to the plant bed
  • Build your plant bed on top of the tank with drainage into the aquarium
  • put your fish in it
  • add your plants
  • Start your system: feed your fish, turn on the pump, make sure the water is pumping through the planting bed and flowing back to the fish.

How much does an aquaponic system cost?

a philodendronAs with anything, it can be done cheaply or very expensively. If you were to purchase an out-of-the-box setup, you can expect to pay between $2,500 and $14,000. What a difference!

You can of course expect delivery and installation as well as product warranties for these prices.

Some manufacturers base their price on square footage per plant and that can go up to around $2.50 to $3.50 per plant, so it can be included in your budget.

If you’re a hands-on person or know someone who can help you build one yourself, you’ll find that it costs a lot less than buying one.

That said, if you don’t know how to build it, better buy one and know that it won’t jam or leak like that.

Which indoor plants grow the fastest with aquaponics?

Some fast growing houseplants for aquaponics include:

  • english ivy
  • peace lily
  • Pothos – Perhaps one of the fastest growing plants for aquaponics.

let’s talk about water

Since water is what keeps fish and plants healthy, there are a few things to keep in mind.

Water circulates and recirculates nutrients from fish to plants and vice versa. Ideally, you want your water to be nutrient rich to keep your fish healthy and your plants thriving.

Water quality, pH and temperature contribute to the proper functioning of aquaponics.

pH levels should be kept between 6.8 and 7.4, where bacteria will work best.

The temperature should be between 65 and 85 degrees if you have warm water fish, and between 55 and 65 degrees if you have cold water fish.

What are the best low-light aquaponic houseplants?

Just like outdoor plants, your aquaponic plants also need light. However, you will find that your fish prefer shade.

They don’t need sunlight to grow and stay healthy, in fact they need light and darkness.

So what do we mean by low light? You should still be able to read a book in low light conditions. If it’s too dark for that, the area is beyond dark and will need extra light to grow the plants.

If the area doesn’t have enough light, you won’t be able to grow food plants like tomatoes. They will only grow with supplemental light. However, lettuce can grow in low light areas.

Plants known to do well in low light areas include:

  • lucky bamboo
  • philodendron leaf heart
  • snake plants
  • peace lily
  • bros

final thoughts

A field of lavender in the article The 10 best indoor plants for aquaponicsOnce you learn and understand how different things come into play in aquaponics, you will be well on your way to success.

One of the best items you can buy is a quality water testing kit to make sure your water isn’t too high or too low, too hot or too cold for the type of fish. which you choose.

A good understanding of water, light, and water quality will keep your system and houseplants running smoothly and efficiently for your aquaponics system to thrive.
