Rockwool drip cover

Rockwool Drip Cover (100–150 mm)

Precision Cover for Rockwool Blocks with Integrated Dripper Guide

The Rockwool Drip Cover is a reusable cover plate for professional irrigation control on rockwool substrates. Designed for blocks with 100 to 150 mm edge length, it improves water distribution, reduces evaporation, and prevents algae growth by completely shielding the block surface from light.

Key Features

Targeted Dripper Positioning
Pre-defined dripper spot openings allow for reproducible placement of irrigation drippers directly over the active root zone.

Light and Algae Control
The opaque surface blocks radiation on the moist rockwool, significantly reducing algae growth.

Evaporation Reduction
The cover stabilizes the moisture balance in the substrate and increases the efficiency of the nutrient solution.

Clean System Setup
Prevents substrate washout, splashing water, and salt crusts on the block surface.
