Matrix Media is a plastic media used inside ZipGrow™ Towers. It is a fiber matrix that offers 290 ft² of BSA (biological surface area) per cubic foot. It is unique from other hydroponic and aquaponic media as it serves as a biological filter and plant anchoring in one.
Matrix Media comes as a long strip, which is folded and pulled through the Tower like a zipper. Plants are sandwiched between the two sides of the fold. Matrix Media is black to disallow high algae growth.
It is made of PET-1 (a type of safe, stable polyester from made from recycled plastic water bottles) with a water-based latex binder to prevent degradation.
