The Charles Dowding Base Tray and Polycarbonate Greenhouse Lid Starter Kit is a premium propagation system developed in partnership with No Dig gardening specialist, Charles Dowding. This UK-manufactured set is designed for longevity, providing a sustainable alternative to single-use plastics and a dimensionally stable environment for early seedling development.
Exceptional Strength and Durability
The kit features a high-clarity polycarbonate greenhouse lid, a material chosen for its extreme durability. Polycarbonate is almost unbreakable, and its resilience has been demonstrated through rigorous testing, including direct impact with a 16oz hammer [watch here]. This tough cover protects young plants from environmental stressors while creating the ideal micro-climate for vigorous growth.
Modular and Efficient Design
Injection-moulded from UV-stabilised, recyclable polypropylene, the propagation and base trays are built to last for many seasons. The kit’s compact dimensions are specifically designed to fit neatly on a windowsill, making it an excellent choice for indoor seed raising.
The bundle includes:
1 x Base Tray and Polycarbonate Greenhouse Lid: A robust foundation for controlled growing conditions.
1 x CD30 Tray (30 Cells): Ideal for higher-volume sowing in a single tray.
2 x CD15 Trays (15 Cells each): Versatile options for smaller batches or different plant varieties.
1 x Charles Dowding Dib Popper: A new, specialised tool made from UV-stabilised ABS that allows for the effortless dibbing or ejection of seedlings.
Better Results, Less Space
By starting seedlings in this professional-grade kit, gardeners can achieve higher germination rates and more efficient growth, even in limited spaces. The system allows for year-round cultivation, extending the growing season and ensuring seedlings are well-established before being moved to the garden.
