Who This Is For
- You are starting high-volume propagation runs because hand-packed media creates too much mess and tray variance.
- You are switching to rockwool for cloning because you need a sterile environment that wont harbor root pathogens.
- You are scaling up your nursery because handling individual plugs takes too long compared to these 48-cell sheets.
What We Found
- We like these 2-inch blocks because they give roots more runway before you have to move them into larger media
- The uniform density prevents the dry spots we often see in lower-grade stone wool that was compressed poorly
What Users Say
- Propagators tell us their rooting success rates jumped once they switched to a media that doesnt mess with their pH
- Large-scale growers say the 48-cell layout lets them move through high-volume clone runs without wasting bench space
Cultiwool 48 Cell Mini Block Sheets (24 Sheets/Case)
Struggling with inconsistent germination rates or disease in your nursery? The Cultiwool 48 Cell Mini Block Sheets provide a sterile, high-performance solution for professional growers and hobbyists alike. These stone wool starter plugs are engineered to create the perfect microclimate, ensuring rapid root development and healthy plant establishment from the very first day. Whether you are starting from seed or taking cuttings, these sheets offer the precision required for high-yield propagation.
Each mini block measures precisely 2" x 2" x 2", providing optimal space for roots to thrive while maintaining a superior air-to-water ratio. Because stone wool is naturally inert, it does not bind or release nutrients, giving you total control over your feeding schedule. Once your seedlings are established, they can be easily moved into larger growing blocks or 1.5 inch cubes without disturbing the delicate root systems.

FAQs
Do I need to soak Cultiwool blocks before use?
Yes, it is recommended to soak stone wool in a pH-adjusted nutrient solution (typically pH 5.5-5.8) to stabilize the medium before inserting seeds or cuttings.
Are these blocks suitable for both seeds and clones?
Absolutely. The 2-inch dimensions provide ample support for cuttings to take root and enough volume for seedlings to develop a strong initial root system.
Can I transplant these into soil?
While designed for hydroponic systems, stone wool blocks can be transplanted into soil or coco coir once the roots have emerged from the block.
How many blocks are in a full case?
Each case contains 24 sheets, and each sheet has 48 cells, totaling 1,152 mini blocks per case.
Do these sheets fit in standard 1020 trays?
Yes, these sheets are designed to be compatible with industry-standard propagation trays for easy handling and transport.
