The SuperDome polytunnel by Bio Green will protect the delicate young seedlings optimally similar to a cold frame or greenhouse from frost and also extreme heat, which in turn ensures safer and more productive cultivation. The roof of the polytunnel comes with a shading material sewn into it so that the young seedlings are protected against the midday sun and heat. Two side openings allow for ventilation and easier plant care as well as watering. The ideal conditions inside the SuperDome will provide you with a headstart of at least 2 weeks in the growing season.
