Rockwool Cubes for Hydroponics


For years, Rockwool has been the go-to medium for starting seeds in hydroponics.

  • Cubes fit nicely in net pot sizes 2″ and larger
  • Each cube has a pinhole for seeds
  • Easily transferrable into whatever system you have once seedlings are ready (Aeroponics, Kratky, flood and drain, NFT, etc)
  • Maintain good aeration while soaking up nutrients and do not inhibit root growth
