Rock Wool Growing Cube / 1 Hole Without Water Groove / 100×100×65mm

Description

This compact rock wool growing cube measures 100×100×65mm with a single circular planting hole at the center of the top surface without water groove, preventing lateral diffusion of irrigation water toward the block edges, delivering water-nutrient solution directly to the core root zone, reducing unnecessary wetting. It is suitable for crops requiring strict moisture control or for high-frequency micro-drip irrigation. The 65mm height provides moderate root space, and the single-plant design allows zero-damage transplanting by placing the entire cube. This product is particularly suitable for propagation stages requiring strict water control and for crops sensitive to root-zone humidity.

Application

Early propagation of cluster tomatoes and cherry tomatoes  (preventing leggy growth)

Propagation of grafted cucurbits  (cucumber, watermelon, melon)

Single-plant cultivation of strawberry mother plants before runner induction

Water-controlled propagation of flowers  (lisianthus, baby's breath)

Research trials requiring precise drip irrigation

Transitional propagation of leafy greens  (lettuce, broccoli) in ebb‑and‑flow systems

Specification

Features

No water groove, precise moisture control: Eliminates lateral water diffusion, concentrates irrigation directly under the root zone, reduces water waste, lowers leaf humidity.

Single pre-formed hole: fitting plug seedlings or germinated seeds, ensuring accurate positioning and upright seedlings during transplanting.

Porosity ≥92%, saturated water absorption ≥850%: Maintains good aeration even under high‑frequency drip irrigation, preventing root rot.

Compatible with automatic sowing lines: The flat top surface  (no channel) allows precise centering of seeding needles, suitable for robotic transplanting operations.
