HOW DEEP SHOULD MY GROW BEDS BE IN A MEDIA BASED SYSTEM?
The standard depth of Aquaponic system grow beds are the same as those used in the hydroponic industry. The depths can vary from 10cm (100mm) to 30cm (300mm) with the deeper the bed, the more problems that can be encountered with cleaning out the roots of plants. The depth only needs to be as deep as the plants roots grow. These depths have enough area to harbor the bacteria needed to make an Aquaponics system stable and successful.
