Professional Large Greenhouse Lid & Universal Large Base Tray
The Foundation for Efficient Bottom-Watering and Superior Root Health.
The Universal Large Base Tray is an essential component for any serious propagation setup. Designed to provide a mess-free and efficient watering solution, this tray allows gardeners to move away from top-watering, which can often disturb delicate seeds and foster disease. By utilising bottom-watering, moisture is delivered directly to the roots, ensuring consistent hydration and a cleaner, tidier gardening workspace.
Innovative Design for Healthier Seedlings
This tray is more than just a water reservoir; it is engineered to enhance plant vitality. When used as a base for propagation modules, it facilitates:
Enhanced Airflow: The tray’s design promotes air circulation around the base of the modules, aiding in the air pruning of roots to prevent spiralling.
Optimal Moisture Control: Seedlings draw up exactly the amount of water they need, reducing the risk of waterlogging and damping off.
Root Vigour: Consistent bottom-watering encourages roots to grow downwards, creating a stronger and more resilient root system.
Unmatched Modular Flexibility
This versatile base tray is the perfect companion for a wide range of the Containerwise professional series. It is compatible with:
Charles Dowding Range: Fits the CD60 long-life tray perfectly.
Standard Series: Accommodates the 15 cell shallow & deep, 28 cell shallow & deep, 40 cell shallow & deep, and 77 cell shallow & deep.
Greenhouse Integration: Can be combined with the Large Greenhouse Lid to create a fully enclosed, high-performance propagator.
Key Features and Benefits
Smarter Watering: Promotes healthier growth and reduces the risk of seedling damage.
Durable and Reusable: Manufactured to the same high standards as the rest of the range for years of service.
Clean and Tidy: Prevents water runoff and soil splash, keeping greenhouse benches or windowsills pristine.
