Give beds and raised planters generous protection with the GroZone Max GroCloche, the large format cold frame that creates a warm, sheltered microclimate for reliable sowing and growing. The elongated tunnel shape sits neatly over rows, salads and young veg, guarding against wind, showers and pests while capturing valuable light and warmth to extend the season at both ends.

A tough, high density reinforced PE cover teams with a durable powder coated steel frame for strength you can count on. Daily access is easy, the long front panel zips on both sides and clips back cleanly so you can water, thin, weed and harvest without faff. Ten roof vent flaps promote steady airflow and help prevent heat build up on sunny days, so seedlings harden off gradually and crops stay happier.

Quality fixings throughout make a difference in use. Webbing ties and hook and loop straps keep the rolled panels secure, corner eyelets allow pegging down, and the rigid base frame sits square on soil, bark or raised beds. Use it for germinating seed, propagating cuttings, protecting strawberries and lettuce, or giving courgettes and brassicas a settled start. Assembly is straightforward with no special tools required.

At AllotMate Essentials we rate Max GroCloche for its useful length and sensible ventilation. It turns an open bed into a controlled space in minutes, then folds away flat at the end of the season. If you want greenhouse benefits without a permanent structure, this is the sweet spot.

Dimensions: 1.8 m length x 0.92 m width x 0.90 m height.
