Air-Pruning Crate for 70mm Tubestock and 66mm Square Pots
The Professional Foundation for High-Performance Root Development.
The Garden City Plastics TR70SBK is an air-pruning crate, specifically engineered to optimise the growth and handling of young plants. Designed for the nursery professional and the serious home gardener alike, this crate is the essential framework for raising high-quality nursery stock. It is fully compatible with 70mm round tube stock pots and 66mm square pots, providing a secure and organised system for large-scale propagation.
Advanced Air-Pruning Technology
The primary advantage of the TR70SBK is its open-mesh base and sidewall design. When pots are elevated within the crate, it facilitates maximum airflow around the drainage holes. This process encourages natural air pruning, preventing roots from circling or becoming pot-bound. Instead, the plant is stimulated to produce a dense, fibrous, and highly branched root system, ensuring superior establishment and faster growth once the plant is potted on or planted out.
Industrial Durability and Ergonomics
Injection-moulded from high-quality, UV-stabilised plastic, the TR70SBK is built to withstand the harsh conditions of a commercial nursery. It is rigid, dimensionally stable, and designed to handle the weight of saturated potting mix without flexing.
Key Features and Benefits
