Twin Canaries Rockwool Mini Blocks 1.5in Propagation Kit – 45 Pack + 5 THCity Stakes

Overview

Discover the Twin Canaries Rockwool Mini Blocks, a 45-pack of 1.5in Grodan cubes designed for propagation, cloning, and seed starting. Each block provides a stable, moisture-friendly microenvironment that can help foster healthy root formation and easier handling for both beginners and seasoned growers.

These cubes are versatile across growing styles. They’re suitable for hydroponics, aquaponics, and soil gardens, offering reliable performance across systems. The uniform size and pre-cut blocks reduce prep time and mess, helping you stay focused on what matters most—your plants.

Key benefits

• Superior root aeration and drainage helps maintain an ideal air-to-water balance, potentially supporting robust root development and nutrient uptake.
• Clean, convenient, and ready to use—soak, plant, and grow with minimal fuss.
• Seamless transplanting lets you move plants into larger Grodan cubes, blocks, or slabs without disturbing roots.
• Compatible with multiple systems (hydroponics, aquaponics, soil) for flexible growing options.

What’s included in the pack

• 45 Grodan mini blocks sized for easy propagation at 1.5 inches.
• 5 THCity Stakes to help support early growth and stability.
• Uniform blocks designed for consistent moisture management and predictable results.

How to use

• Soak blocks according to packaging instructions to achieve the right moisture level.
• Insert seeds, clones, or cuttings into each block and keep under appropriate light and temperature.
• When roots fill the block, transplant into larger Grodan cubes, blocks, or slabs with minimal root disturbance.
• Use across hydroponic, aquaponic, or soil setups and adjust moisture to prevent overwatering.

In real-world use, gardeners often start seedlings in a controlled, consistent environment and then expand to larger media as roots develop. The included stakes add stability during early growth on busy benches or shelves.
