Description

A greenhouse for keen gardeners, the 8x12 Magnum Greenhouse 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; 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.

Toughened safety glass is fitted as standard. 4mm twinwall UV-stabilised insulating polycarbonate is available as an optional upgrade. Both are 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. All of the Magnum range from Halls Greenhouses feature generous 1.51m eaves and 2.58m ridge height, and are 2.57m wide. This 8x12 greenhouse is 3.84m deep and offers a base area of 9.9m2.

The frame of this greenhouse is guaranteed for 12 years. It is essential that all greenhouses are placed on a firm level surface. For increased stability, we recommend the optional greenhouse base designed for Halls' greenhouses.

This superb garden greenhouse is available in three sizes (8x10, 8x12 and 8x14) and each size is available in standard silver or with a green powder-coated finish. You are sure to find the right greenhouse for your gardening and grow your own requirements.
