Air Stones

  • Produce smaller bubbles allowing for faster and easier transfer of oxygen into solution
  • Are more prone to clogging with root mass or particulates.


Air Diffusers

  • Can be taken apart and cleaned. Current Culture recommends that they be discarded between grows.
  • Are lighter and more flexible.
