A greenhouse for keen gardeners, the 8x12 Magnum Greenhouse with green powder-coated aluminium frame from Halls Greenhouses boasts a variety of features sure to please any gardening enthusiast. This large greenhouse is designed to offer generous headroom to make working in your greenhouse a pleasure. You can personalise the interior space by upgrading with optional greenhouse staging. This includes 1- or 2- tier aluminium staging with slatted shelves finished in green; a 3-tier seed tray frame staging which will hold 15 seed trays; and a 2-tier potting bench. The wide smooth-action, sliding double doors offer easy access with wheelbarrows and planters. The greenhouse comes with 4 roof vents and we offer optional extras designed to allow you to create the optimum growing conditions for your plants: an auto vent opener, a louvre window, and an auto louvre control. You can also opt for a greenhouse heater. As standard, this greenhouse is glazed with 3mm horticultural glass. We do recommend upgrading this for better performance and safety. You can choose to upgrade to long panel toughened safety glass or to 4mm twinwall UV stabilised insulating polycarbonate. Whichever option you choose, they are all easy to install with clips and rubber gaskets. Robust, durable and rust-resistant, the aluminium frame is further strengthened by diagonal bracing, cast iron bolts and reinforcing brackets. The frame has been powder-coated in green for a striking finish that will blend effortlessly with your garden for a modern design.
