Charles Dowding & Huw Richards Polycarbonate Lid System
This premium propagation system has been developed in conjunction with gardening specialists Charles Dowding and Huw Richards to create the ideal micro-climate for seedling success. Designed and manufactured in the UK, the system is perfectly dimensioned to fit on a window ledge, providing a professional-grade growing environment in a compact footprint.
Exceptional Durability and Resilience
The set features a high-clarity polycarbonate greenhouse lid, a material chosen for its extreme strength and near-unbreakable nature. Its resilience is so significant that the lid has been tested to withstand direct impact from a 16oz hammer. This robust cover protects delicate seedlings from the elements while maintaining the controlled conditions necessary for year-round cultivation.
Superior Root Health Engineering
The base tray is injection-moulded from tough, UV-stabilised recyclable polypropylene, ensuring it remains rigid and dimensionally stable for many years. The internal base is engineered with protruding ridges that serve a dual purpose:
They provide a stable, level foundation for the propagation trays.
They facilitate essential air pruning of the roots, preventing spiralling and ensuring stronger plant establishment.
Universal Modular Compatibility
This versatile system is designed to work seamlessly with both the Charles Dowding (CD) and Huw Richards (HR) ranges of long-life propagation trays:
Huw Richards Trays: The base perfectly accommodates either 1 x HR20 tray or 2 x HR10 trays.
Charles Dowding Trays: The system is also designed to fit 1 x CD30 tray or 2 x CD15 trays.
Sustainable Growth
By investing in this high-quality, reusable system, gardeners can significantly reduce their reliance on flimsy, single-use plastics that contribute to landfill. It is the ultimate foundation for anyone serious about increasing germination rates and growing more efficiently in limited spaces.
