150mm Rockwool Cubes | Cultiwool Donut Ring

Commercial-grade 150mm rockwool cubes engineered for uniform irrigation, controlled dry-back, and scalable hydroponic production.

Professional Rockwool Cubes for Controlled Environments

Cultiwool 150mm Rockwool Cubes with Donut Ring are built for commercial cultivation where irrigation precision and crop consistency matter. Designed for large-scale hydroponic systems, these cubes eliminate uneven hydration, prevent dry cores, and provide a stable root zone across every block in your facility.

The integrated donut-ring planting chamber distributes water evenly from the drip point outward, improving saturation uniformity and reducing channeling. Bottom drain grooves promote runoff control and keep production areas cleaner during heavy irrigation cycles.

Why Commercial Growers Choose Donut Ring Cubes

• Even water distribution: Circular planting cavity improves hydration balance and reduces dry pockets.
• Improved runoff control: Bottom grooves move excess solution away from the root zone.
• Consistent fiber density: Uniform porosity supports predictable oxygen and moisture balance.
• Stable, inert media: Allows precise EC and pH steering in controlled irrigation programs.
• Designed for scale: Case and pallet quantities support continuous commercial cycles.

Available Cube Sizes (Metric)

• 150 × 150 × 150 mm – Extended root zone for longer vegetative cycles.
• 150 × 150 × 100 mm – Reduced height for tighter canopy management and faster dry-back.

Operational Benefits at Scale

Rockwool remains a preferred substrate in hydroponic production due to its predictable structure and inert profile. These 150mm cubes allow growers to:

• Standardize irrigation schedules across multiple rooms
• Reduce variability between plant sites
• Minimize transplant stress from propagation to production
• Maintain cleaner grow floors through directed drainage

How to Use

1. Pre-condition: Saturate cubes in pH-adjusted water (5.5–5.8) until evenly hydrated.
2. Insert propagation plug: Place clone or seedling into the donut-ring chamber.
3. Irrigate with runoff: Maintain 10–20% runoff to stabilize EC levels.
4. Monitor substrate data: Adjust irrigation frequency to manage dry-back strategy.
