The second difference comes from the varying components. hydroponics systems are very sterile, and there is no need for any extraneous growing media to support the plants or root systems. aquaponics, on the other hand, needs an environment around the roots to harbor the beneficial microorganisms. hydroponics doesn’t need deep growing media to support the plants or root systems. some hydroponic systems even don’t use any growing materials. startup cost/speed. Hydroponics is an increasingly popular method of growing plants that uses a nutrient-rich solution with a water base, which means that soil isn’t used at all in a hydroponics system. instead, the roots of the plants are supported by such substances as peat moss, clay pellets, perlite, and rockwool. when you’re looking to create or use a hydroponic system to grow plants, there are hundreds.
