Cons of Jowlawn 1″ Rockwool Cubes
Handling Precautions: The transverse texture of the rockwool requires wearing gloves and using scissors for cutting, rather than tearing by hand.

Potential for Compaction: If not handled carefully, the cubes may become compacted, reducing their effectiveness as a hydroponic substrate.
