Rock Wool Propagation Plug Round Plug 40×40mm For Tomato Cutting Propagation

This product is a large-size round rock wool propagation plug, with dimensions of 40mm in diameter and 40mm in height, suitable for tomato cutting propagation. Made from high-density rock wool substrate, it offers excellent physical support and moisture regulation, making it suitable for rooting of cuttings and seedling cultivation. With a stable structure, it can be used independently or placed in nursery trays.

Suitable for tomato cutting propagation, it can also be used for cutting propagation of other solanaceous crops, cucurbits, and more.

Widely applied in greenhouse seedling cultivation, plant factories, and scientific research experiments.

• Larger Volume for Cutting Stability: The 40*40mm size offers ample substrate volume, ensuring stable support for tomato cuttings to prevent tipping while providing sufficient space for vigorous root development.
• Optimized Air-Water Balance for Rooting: The rock wool matrix maintains high water retention without compromising aeration, creating a humid yet non-waterlogged environment at the cutting base, significantly improving rooting rates and root quality.
• Sterile Medium Reducing Disease Pressure: Free from soil-borne pathogens, the rock wool minimizes risks of stem rot and root rot during propagation, making it especially suitable for high-value or disease-sensitive varieties.
• Versatile and Easy to Use: Compatible with both manual and automated cutting operations. Plugs can be directly transplanted into rock wool blocks or cultivation channels, reducing damage from secondary transplanting.
