Tomatoes in Aquaponics – Characteristics and Requirements

aquaponics tomatoes

Believe it or not, aquaponics tomatoes are some of the most common options for beginners. Tomatoes are juicy and taste good when grown naturally, but they are also less demanding than other plants. With all these, they do have their challenges, and learning about their unique demands is mandatory in order to gain as much as possible from this experience.

It is worth noting that tomatoes are not actual vegetables. Despite being put in this category, they are actually berries. They were originally grown in South America and pushed all over the world. Good weather and lots of nutrients are some of the main challenges associated with such a system, but then, what else should you know before digging in?

Temperature requirements

Tomatoes are quite forgiving when it comes to temperature. Make sure you maintain at least 65 degrees F and never exceed 85 degrees F. While they are known for preferring warm weather conditions, they will not really thrive if the temperature exceeds 95 degrees F – they will simply stop growing. While the temperature range is a bit broad, try to maintain it at about 75 degrees F, and your tomatoes will pleasantly surprise you.

It is essential to ensure good drainage. Apart from requiring lots of water, tomatoes do not do well if they are constantly submerged.

pH requirements

The pH levels in the water are not as broad as the temperature. Keep the pH between 5.5 and 6.5, and you should have no issues at all. Other plants could do with higher pH levels, but then, a little research is mandatory. You will need to consider the overall needs of other plants if you plan to mix them – not to mention the fish requirements.

The right fish for aquaponics tomatoes

Aquaponics tomatoes grow better when matched with the right fish. In other words, the temperature and pH requirements should be similar for the system to work. From this point of view, trout is one of the most common choices for such an environment. But then, the temperature must be kept at the lower limits, meaning your tomatoes will grow a bit slower than normally.

Another great option implies using fish that love warm water. Crappie will not let you down, not to mention koi or tilapia. Even goldfish and angelfish are suitable for tomatoes – despite not being edible. Again, it only depends on your personal preferences.

Nutrient demands

There are a few spacing requirements when planting tomatoes in your aquaponics system. Generally speaking, you should keep plants about one or two feet apart. They love sunshine, so make sure they get plenty of it. If well looked after, they can go up to six feet in height. You should also come up with a structure to ensure they grow upwards – otherwise, they will go sideways and interfere one with another.

Keep an eye on the levels of potassium in the water. Tomatoes have high nitrogen requirements, especially in the early growing stage. Once the plants are established, they will need more potassium. Potassium is responsible for pushing the flowering process into fruiting. Surprisingly for some, tomatoes accept salt in the water – in fact, salt is actually recommended.

Apart from keeping an eye on all these, make sure you look after the plants by trimming them once they get up to a couple of feet. You can keep bushes – meaning you have to trim the top part – or just trim the stems off and let the plant grow further.

To make tomatoes grow faster, you can remove the leaves growing at the bottom – not higher than 10 inches. This way, most of the nutrition will go towards the top.

Growing speed

If well maintained, you can get up to 35 aquaponics tomatoes from a single plant. There are more species of tomatoes, and each of them comes with various specifications – simply look at the wide varieties available in supermarkets.

Maintain the right conditions, and the plant can grow in no time. The first few weeks will give you decent growth. Give your plants a few more weeks, and you will end up with flowers. You can harvest tomatoes a couple of months after planting them. Even if you pick the tomatoes, the plant will keep growing. At this stage, it should be a couple of feet in height. Should you need more tomatoes, it will keep producing.

Conclusion

As a short final conclusion, aquaponics tomatoes are excellent from multiple points of view. They are easy to look after, and their requirements leave no room for guesswork. You can purchase such plants from pretty much any local farm. But then, you should know they are also vulnerable to a bunch of diseases. Therefore, opt for a strong variety and healthy plants.

Despite being simple and straightforward, you might want to discuss your options with someone who already deals with aquaponics tomatoes and perhaps get some seedlings from them – this way, you know for sure that your plants are healthy and proven to grow. Plan everything accordingly before diving into this venture. Many beginners choose tomatoes because they are tasty and easy to grow. Just like any other plant, they do have a few characteristics you should never overlook. Bring in the right fish, maintain the ideal conditions, and you should have some tasty tomatoes within weeks only.
