Rock Wool Growing Block Without Pre-Drilled Hole 75×75×65mm For Cut Rose Cutting Propagation

Description:

This product is a rock wool growing block without pre-drilled hole , measuring 75×75×65mm, specifically designed for cut rose cutting propagation. The block surface has no pre-formed hole, allowing cuttings to be inserted directly into the substrate with flexible operation. Made from high-purity rock wool fibers, it offers excellent water retention and aeration, providing a stable environment for rooting and early growth of rose cuttings.

Applications:

Suitable for cutting propagation of cut roses, as well as vegetative propagation of other woody ornamentals. Widely used in cut flower farms, greenhouse nurseries, and professional propagation enterprises.

Specification

Feature:

- Large Block Size Ensuring Cutting Stability: Provide ample substrate volume to securely encase the base of rose cuttings, preventing tipping and displacement, promoting dense root development.

- Open hole-Free Design for Flexible Operation: The block surface has no pre-drilled hole, allowing growers to flexibly select insertion positions and depths based on cutting thickness and variety characteristics, particularly suitable for precision manual cutting operations.

- Balanced Air and Moisture for Optimal Rooting Microenvironment: The rock wool matrix maintains high water retention while ensuring adequate aeration, creating a moist yet non-waterlogged microenvironment at the cutting base, effectively prevents cutting rot.

- Sterile Substrate Reducing Disease Transmission Risk: The rock wool is heat-sterilized, free from soil-borne pathogens and weed seeds. During rose cutting propagation, it effectively reduces the incidence of common diseases such as stem canker and root rot, ensuring healthy plantlets and improving yield rates and commercial quality.
