A great article from WhiteFence Savings on why Aquaponics is a GREAT way to grow.

Aquaponics is the combination of aquaculture and hydroponics. The former concerns the raising of aquatic animals, while the later deals with growing plants or vegetables in water. By combining the two, aquaponics creates a mutually beneficial system where water and nutrients are recycled naturally. By feeding the waste water from an aquaculture system into a hydroponics system, essential nitrates and nitrites are created in a natural way. This leaves a clean, healthy environment for the fish, while providing nutrients for the plants. In this list, you will find ten more excellent reasons why you should consider a aquaponics system.

1. Weeding – With aquaponics, it’s simply not an issue. The systems don’t use soil or any processes that enable weeds. Without weeds, you can concentrate on growing vegetables and watching your fish grow. That means that you can say goodbye to that lower back-pain from constantly having to bend down to pull out weeds.
2. Reduced Space – In aquaponics systems, plants and vegetables are constantly fed through water and nutrients. This means that the footprint needed is significantly less than with traditional crop farming. As long as each plant is getting enough light, you can effectively grow plants in much closer quarters.
3. Artificial fertilizer – Forget about ever having to buy artificial fertilizer once you set up an aquaponic system. The only additional food that your plants will need is supplements to balance nutritional intake. However, not all systems will require an additional supplement, which means 100% savings on fertilizers. Most important of all is the fact that you can’t actual add fertilizer to the system, as it will kill any fish you have in the tank.
4. Faster Plant Growth – With a constant feed of essential nitrates, plants grow much faster in aquaponics systems. The level of output is also affected by the reduction in space, allowing the system to produce higher yields than traditional soil planting. Also, aquaponics systems are improving all the time, which can only mean that even faster plant growth will be possible in the future.
5. Water Reduction – All water in aquaponics systems is recycled. This means that your overall water usage will greatly reduced, which is good for both the environment and your pocket. There is little to no labor involved in the process, either. Apart from occasional top-ups and cleaning pumps and filters, you won’t have to lift a finger to maintain optimum water levels.
6. Organic Systems – Provided that you give your fish stock only organic feed, an aquaponics system is completely eco-friendly. You will benefit from only the most natural crops and plants, while your fish are fed on healthy organic products, too. This is a win-win for humans, plants and fish. You can’t always guarantee that store bought vegetables are organic, but you can with your own aquaponics system.
7. Sustainability – As your aquaponics system is effectively a self-sustaining ecosystem, you don’t have to worry about eroding resources. Once you determine the best level of production, you can maintain growth and output at a constant level. Soil systems, on the other hand, drain their ecosystem of resources, requiring you to constantly re-balance nutrients and the soil’s health.
8. No Pesticides – With soil, you have to use pesticides to prevent plants from becoming damaged or destroyed. As aquaponics does not use soil, related pests are automatically out of the picture. What’s more, your plants won’t be absorbing any toxins from pesticides, making for a much healthier crop.
9. Dollar Output – If you sell your crops, the increased yields from aquaponics will also increase your bottom line. With the huge demand for organic produce, you will find that your customer base will grow, too. Don’t forget that you also have fish stock, which means aquaponics potentially provides a dual revenue stream.
10. Labor Reduction – Less labor for you, less use of energy, and less time spent working in your garden in general. After you install your aquaponics system, you will notice a significant drop in the amount of time you spend slaving over gardening related tasks. This gives you more time to enjoy your garden, while still being able to reap all the rewards.

So there you have it – ten ways that you can benefit from owning an aquaponics system. Reduced labor, higher yields, healthier animals and plants, and more money in your pocket. With so many positives, you really have nothing to lose. Plus, with an aquaponics system, you always have the best of two worlds.
