The 8x12 Magnum Greenhouse from Halls is a large greenhouse ideal for keen gardeners. Its excellent range of features makes gardening and grow-your-own pursuits a pleasure. This garden greenhouse is constructed from long-lasting, low maintenance aluminium framing further strengthened by cast iron bolts, diagonal bracing and reinforcement brackets. 3mm horticultural glazing is included as standard. For safety and performance, we would recommend upgrading the glazing. This can be upgraded to long panel toughened safety glass or to 4mm twinwall UV stabilised insulating polycarbonate. All are easy to install with clips and rubber gaskets. Wide, smooth-action, double sliding doors provide easy access to the greenhouse while 4 roof vents allow control of interior conditions. Optional extras include an autovent openers for the windows, a louvre window, and an autolouvre control.

Optional extras include greenhouse staging to maximise space.

The always popular 2- tier potting bench and a greenhouse heater are also available. All greenhouses should be placed on a firm, level surface.
