It's double doors provide you with a helpful addition, allowing clear access for wheelchairs, plenty of room for your wheelbarrow and the option of extra ventilation when required. The extra ridge height adds another dimension providing you with greater headroom and height for the development of your taller plants. The range contains four strong models.

Before you choose your Halls Magnum greenhouse, ensure you have checked the available space - the Magnum greenhouse comes in 4 sizes. Remember not to make the mistake of buying too small. Ideally, pick the area with maximum sunlight and the greatest protection from the wind and ensure you choose the correct glass type to suit your position - all the Magnum greenhouses come with two glazing options, either horticultural or toughened glass. Setting up your AGL greenhouse is not going to be difficult, at most it will take you a weekend.
