However, the raft based aquaponics system uses a raft instead of growing media that floats above nutrient-filled solution to support the plants. so, for your hydroponic/aquaponics system, always choose a grow medium that serves your needs, gives you the greater yields and is the simplest to maintain.. Aquaponics grow media is a soilless natural or synthetic material that functions as a support body for your crops in the system. like soil, it is a component that protects and ensures plant roots are anchored in the right position and allows seeds to germinate safely within the material, instead of in the ground like in traditional gardening.. In this post, we will speak about aquaponics grow bed media and water, two vital elements of an aquaponics system. the grow bed medium is the plant’s environment, while the water is the fish’s environment. the two are connected, and if there are issues in one, they will manifest themselves in the other..
There are three grow bed zones in the media-based aquaponics system, and each zone has different functions in the system. zone 1 - the surface or dry zone. this area is within the first 1- 2" (5cm) of the grow bed.. These dimensions are provided for the aquaponic designs outlined in this publication for a media bed of 1–3 m2 with a media depth of 30 cm, with an incoming water flow rate of 200–500 litres/h for each bed. for large grow beds, all of the components would be larger.. Media beds in hobby-scale aquaponic systems often account for 100% of the plant growing area of the system. in small-scale, hybrid (mixed media bed and deep flow growing zones) aquaponic systems, they generally account for the minority of the plant growing area. in either configuration, media beds act.
