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

Product Description

The 40×40×40mm trapezoidal propagation plug provides up to 64 cm³ of root development space. The rock wool fibers exhibit structural stability, resisting collapse even after repeated wetting. Designed for crops requiring extended nursery periods or producing large, vigorous seedlings, this plug allows big tomatoes, melons, and other long‑cycle plants to form a dense root ball before transplanting – significantly boosting early yield after field or greenhouse planting.

Application Scope

Suitable for long-cycle solanaceous crops, large cucurbits, High-value cash crops  (strawberry, tobacco), and other crop requiring >30 days of seedling stage

Specification

Key Features

Extra‑large root zone: Single plug volume is >2.5 times that of the small size, allowing 35‑45 days of unrestricted seedling growth.

Controlled‑release matrix: Slightly higher fiber density slows nutrient release, reducing irrigation frequency and suiting automated drip systems.

High mechanical strength: Plugs remain intact even when lifted by the plant – ideal for robotic gripping and handling.
