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
