Description
Designed for commercial farms and hydroponic facilities, Cultiwool Rockwool Grow Cubes with Donut Ring deliver reliable rooting, precise irrigation, and consistent performance in bulk.
These professional-grade cubes eliminate dry cores, improve drainage, and support predictable crop cycles at scale.
Why Choose Bulk Rockwool Cubes Even irrigation: Donut-ring planting hole distributes drip flow evenly to prevent dry centers or oversaturation.
Drainage built in: Bottom grooves move runoff away to reduce standing water and cleanliness issues.
Stable fiber density: Consistent structure maintains uniform porosity for balanced oxygen and moisture.
Commercial quality: Manufactured for large-scale farms where every block must perform the same, crop after crop.
Inert medium: Enables precise EC and pH control—ideal for irrigation steering in controlled environments.
Sizes & Pack Options 6″ × 6″ × 6″ (Donut Ring) Case — 48 cubes: Ideal for testing layouts or smaller zones.
Pallet — 768 cubes: Bulk supply for commercial programs. 6″ × 6″ × 4″ (Donut Ring) Case — 64 cubes: Tighter canopies or quicker dry-back strategies.
Pallet — 1280 cubes: High-volume propagation & production.
How to Use Pre-condition: Soak cubes in pH-adjusted water (5.5–5.8) until evenly saturated.
Insert propagation plug: Place seedlings or clones into the donut-ring chamber for uniform hydration.
Irrigate consistently: Run cycles with 10–20% runoff to maintain balance and avoid salt buildup.
Monitor EC & pH: Use the cube’s porosity to fine-tune feeding and optimize plant response.

It distributes water evenly through the cube, preventing dry cores and supporting uniform root development.
Do I need special grow tables? No.
These cubes work on standard benches, flood tables, or concrete floors.
Can rockwool cubes be reused? For commercial farms, reuse isn’t recommended.
Single-cycle use supports hygiene, consistency, and disease prevention.
Which size should I pick? Choose 6″×6″×6″ when you want a larger root zone or longer veg; choose 6″×6″×4″ for tighter canopies or faster dry-back strategies.
Both include the donut ring and drain grooves.
Are these suitable for hydroponics? Yes—rockwool is widely used in hydroponics for its predictable water/air balance and inert profile.
