Product 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

  1. Pre-condition: Soak cubes in pH-adjusted water (5.5–5.8) until evenly saturated.
  2. Insert propagation plug: Place seedlings or clones into the donut-ring chamber for uniform hydration.
  3. Irrigate consistently: Run cycles with 10–20% runoff to maintain balance and avoid salt buildup.
  4. Monitor EC & pH: Use the cube’s porosity to fine-tune feeding and optimize plant response.

Frequently Asked Questions

What does the donut ring do?
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.
