Aquaponics: The Cost-Effective, fun, interactive way to grow plants indoors!
Aquaponics is probably the most efficient method of growing food today. It combines aquaculture (fish) and hydroponics (growing plants without soil) in a system that results in zero waste, recycles water almost infinitely, and removes the need for fertilisers or chemicals!
While aquaponics systems are often used in commercial settings, smaller-scale systems are great for people who want a sustainable way to grow their own food at home year-round, and enjoy some greenery indoors! Check out the Aquasprout here!
So what's the big hoo ha? We'll tell you...
1. It Produces Zero Waste
When growing fish in a controlled environment, their waste has to be removed or the buildup of ammonia could poison them. Instead of pouring that waste back into the environment, it is fed through a filtration system to remove solids, and then through soilless beds of an aquaponic system where it delivers nutrients to plants’ roots. By the time the water cycles back to the recirculating aquaculture system where the fish live, it’s clean and ready to be used again.
2. It Uses Small Amounts of Water
Once the original water has been added to the tanks (most experts recommend first-timers start with a 50L tank, this zero-waste ecosystem only loses small amounts of water through transpiration and evaporation. A slight top-up approximately once a week or so should keep water levels in check. Compare this to a plot of land that needs regular irrigation, or an aquaculture system that has to be replenished on a continual basis to ensure fish don’t perish from their own waste.
3. It's Low-Maintenance
Once it’s set up, most people only spend five to 10 minutes a day tending to their aquaculture system. Once a week, make sure to check pH and ammonia levels and clean some of the components. Otherwise you can forget weeding, straining your back, or skinning your knees, and donate the tools you’ve collected for farming soil. Aquaponics is incredibly self-sustaining if set up correctly.
4. It Requires No Chemicals
Most industrial food systems require huge inputs of fertiliser and pesticides to grow, which can harm the environment. The Union for Concerned Scientists published a report about conventional farming in which they expressed grave concern about our overuse of chemicals to grow food. They describe how chemical fertiliser runoff adds to global warming emissions and creates “oxygen-deprived ‘dead zones’ at the mouths of major waterways,” among other things.
Perhaps the best part of aquaponics is its versatility. Just about anyone with space can grow fruit, fish, herbs, and vegetables at home. Or, if you are short on time and nervous about creating the required balance to ensure the fish don’t grow so fast that the system can’t sustain itself, you can purchase automated systems like the the Aquasprout here!
5. It Reduces the Occurrence of Pests
Closely linked to the absence of chemicals is the absence of pests. Since aquaponics doesn’t require soil, it reduces the presence of the kinds of critters that can compromise your hard-earned crops. Root rot is less common as well, provided the water drains properly.
So there you have it! Get started today and grown your own food at home for a greener life that will benefit you and the environment!
