  1. hey all,

    I am in process of growing my first plant and was wondering if I can use medium to large size fish tank gravel as a grow media for a bubbleponics or hydroponics system? any info will be greatly appreciated..
  2. I have a friend that uses washed pea gravel with success, so I'm gonna say yes. (He's a cheap S.O.B.):D
  3. Fish like alkaline water, just make sure that the fish medium won't affect your ph. Don't think it should but just a heads up. Also, I would try to get a kind that is porous, similar like hydroton.
  4. thanks for the info..I'm cheap as well....

  5. I will definetly consider that...and will try to find some gravel that looks closest to the hydroton..
  6. My first hydro unit i made used rockwool blocks on fish tank gravel. the roots loved the shit.
