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.
