Hydroponics and aquaponics are very similar in every way except hydroponics requires addition of fertilizer and there’s no fish in nutrient solution.
In aquaponics, plants and fish live a symbiotic life with fish feeding plants, and plants cleaning and filtering fish’s environment.
The fish waste becomes plant’s food source, consequently, plants’ roots filter water and keep tank clean. In essence, aquaponics could be considered a miniature ecosystem because both plants and fish are thriving in same environment.
Aquaponics offer benefits to both Gardener’s and Fish Farmers. Fish Farmers may utilize aquaponics if they have difficulty disposing nutrient rich fish water, while hydroponics growers benefit from having a constant supply of free plant food – eliminating need to purchase commercial fertilizers.
Unlike hydroponics or aeroponics, aquaponics is still a relatively new cultivation technique. As more technology is developed and process is refined, it could potentially become a space and money saving process for producing fish, vegetables and herbs.
