Grodan Rockwool Gro-Block - Wrapped 8x8x8 Big Mama

The Big Mama is the largest block and enough to grow out most vegetables and some fruits for the entire life span of the plant.

When your starter has outgrown its home, showing three leaves, or roots reaching one 1” below the cube, Hugo is happy to receive the transplant. 

Hand water or use with drippers or in Ebb & Flow (Flood) systems.
