Description
Cultiwool 4" x 4" x 2. 5" Blocks feature the innovative Donut Ring and Optidrain drainage system.
The donut ring — an industry first from Cultiwool — is a water chamber surrounding the plug hole that ensures perfectly uniform water distribution throughout the block and eliminates dripper positioning errors.
Drainage width grooves on the bottom improve waterflow, reduce ground contact surface, and prevent disease transmission through weak roots.
These low-profile blocks are ideal for crops requiring a shallower root zone.
