36×36×40mm Trapezoidal Propagation Plug - Rock Wool Growing Media

The 36×36×40mm trapezoidal propagation plug strikes an ideal balance between compactness and root-zone capacity. Its 36mm square base offers double the root space of smaller plugs while maintaining a 40mm height for vertical root elongation. Hydrophilic-treated rock wool fibers ensure rapid wetting and uniform nutrient distribution, making this plug particularly suitable for medium-to-long cycle vegetables such as solanaceous and cucurbit crops.

Suitable for industrialized seedling cultivation of tomatoes, peppers, sweet peppers, cucumbers, watermelons, and medium-to-large-sized flowers

• Balanced shoot-to-root ratio: The moderate volume promotes coordinated growth of above‑ and below‑ground parts, leading to quick recovery after transplanting.
• Dual-function hydraulics: Directional fiber arrangement creates vertical water channels, preventing waterlogging while retaining adequate moisture.
• Direct placement into grow blocks: No need to remove the plug – embed it directly into rockwool grow blocks or slabs for zero‑stress transfer.
