Boosts Oxygen Supply to the Root Zone

Our Hydro Clay maximizes air flow to your plants root zone via the numerous open pathways which the media creates. Other media that compact induce oxygen starvation which slows plant growth wherein you are guaranteed optimal air flow with Hydro Clay for expedited plant development.


The Incredibly Versatile Substrate

Our Hydro Clay is incredibly versatile and can be used as a stand alone medium, blended with other substrates, or to line the bottom of the pot for optimal drainage. When used on top, Hydro Clay has the ability to reduce algae, fungus gnats and it also prevents unwanted weeds on the surface by keeping the top of the medium dry.


Perfectly Clean & Inert Media

Our Hydro Clay is a natural growing medium that contains no harmful or undesirable substances.  Hydro Clay is inert – meaning that it has a neutral pH, is resistant to chemicals and will not break down as easily as inferior products in the market and can be reused
