These poly cloches act as mini greenhouses, retaining heat and humidity and making them ideal for ripening crops and pre-warming ground for early planting. Our pop-up cloches self-assemble in seconds - simply open the bag and they pop into shape. No work, no fuss and no tools needed! Use them on fruit & veg patches, over raised beds or put them inside larger poly tunnels for double insulation of vulnerable plants during winter. Available in a range of sizes as singles or great value multipacks.
