The Green Magnum 108 greenhouse from the Halls Greenhouses range. The Green Magnum is a must for the real enthusiast. It's strong aluminium frame ensures this spacious and stylish structure is completely safe. Double sliding 1.20m wide doors are provided, allowing generous access and giving plenty of room for your wheelbarrow. The extra ridge height provides you with greater headroom and the four standard roof vents offer extra ventilation. Constructed from long-life, low maintenance green painted aluminium framing, complete with diagonal bracing - all offered at a truly economical price. As it's crucial to support your greenhouse upon a firm foundation, we do recommend that you select the optional 125mm (5") green painted base rail kit, which will also enable easier installation. Basic pricing includes standard horticultural glazing, however for safety in a public place, or where children or elderly people are present, large pane toughened glass should always be chosen. Self assembly only (instructions supplied).
