You could be growing tomato plants using aquaponics anywhere that you create a System which allows you to successfully grow fish and the plants that you want to produce.  Remember, whatever we do has an impact on the entire system. One of the main things to remember, is to thoroughly research the impact and the effects of any changes that you make upon the fish and your tomatoes.  Keep it organic, keep records, and follow a plan.

Aquaponic systems grow fish in a water tank. Your crops, such as tomatoes, then filter the tank water before it returns to the fish. The crop gets its nutrients from the tank water.  You will need to perform some experimentation as you learn about the fish you grow, the produce you want to grow as well as any automation that you can add to make the system work more efficiently for you.

Growing Tomatoes Plants and Aquaponics


An aquaponic system chemical balance is in constant fluctuation.  Test often, make smaller adjustments, and ask questions.  By building and maintaining a sustainable aquaculture system, you can create a sustainable life. Not work free, but where do you want to go with your system?  Do you want to sell your produce and the fish that you grow?  Do you want to let it be almost completely automated?  Remember that outsourcing is acceptable if you plan on taking time off.


Here are some basic steps for growing tomato plants using aquaponics:


Raise tomato plants to seedlings or purchase tomato seedlings from an organic grower. Do not  use any pesticide or fertilizer in seedlings for your aquaponic system.

Use growing media in your aquaponic growing area. It provides tomato roots better support than free-floating systems, insert stakes into growing media. Tie strings knotted to the edge of the growing area or lay a metal screen over the media surface to anchor the stakes.  Suspend netting or strong string to a frame to support growing tomatoes.

Test the pH of the growing media and the water coming in from the fish tank. Tomatoes grow best in this system at a pH of 5.8 to 7.2. Adjust the pH with organic fish-safe aquatic pH stabilizers if you need to adjust it.

Transplant the tomato seedlings once the pH is stabilized. Cover the root ball with a light layer of the growing media, unless you are growing the tomatoes in compost. Be careful not to use a heavy media on top of the root ball, as it can suffocate the roots and add to the growth of disease.

You can add earthworms, preferably red wigglers to the growing media to reduce anaerobic bacteria that are unhealthy for tomatoes. The worms also supply the growing media with minerals and organic matter that the plants can use for food.

Make sure that you monitor the phosphorus level in your system at least twice per week to keep it in balance as needed. If the phosphorus rate is low, add organic aquatic phosphorus fertilizer as needed.


As you are learning about aquaponics, I highly recommend starting small, growing tomato plants using aquaponics and experimenting with it.  What if you do not like the work or the learning curve is more than you want to deal with?  It is better to experiment when the cost is lower.  Then you can always increase the scope of your aquaponics system once you are confident in your abilities and have your plan in place and the bugs (pun intended) worked out.

Again, growing tomato plants using aquaponics is one of the best ways to learn the challenges of growing using an aquaponics system.
