Agricultural Rock Wool Square Propagation Cube – 50×50×50 Mm

Description:

This product is a large-format independent cubic propagation block measuring 50×50×50 mm, designed for short to medium cycle crops, rooty systems, or plants requiring larger growing space, such as leafy vegetables, and ornamentals. With a volume of 125 cm³  (approximately twice that of the 40 mm cube), it supports seedling growth for 6–8 weeks within the block without the need for transplanting. The product retains the independent block format, requiring no nursery trays, with natural gaps between blocks for aeration. It is especially suitable for grafting nursery and dual-plant co-cultivation,

Applications:

Ideal for full-cycle cultivation of lettuce, spinach, pak choi, kale, and other hydroponic leafy greens. Widely used in plant factories, commercial hydroponic greenhouses, and large-scale hydroponic farms.

Specification

Feature Advantage:

- Large Square Format for Full Root Expansion: The 50×50×50mm dimensions provide ample substrate volume to accommodate root growth during the mid-to-late stages of leafy green production, preventing root crowding, enhancing nutrient uptake, and improving yield per plant and product quality.

- Stable Structure Supporting Upright Growth: The square block provides reliable physical support, keeping leafy greens upright throughout the growth cycle. This improves canopy light exposure, air circulation, and space utilization while reducing disease incidence.

- Sterile and Inert for Precise Nutrient Management: The rock wool is chemically stable, with no impact on nutrient solution pH or EC, allowing precise control over nutrient formulations. The sterile nature minimizes root disease risks, making it suitable for long-term, continuous cultivation and standardized production systems.
