Gardeners in search of typical Halls glasshouse quality, but a larger structure than most of the company’s models, need look no further than the Halls Magnum greenhouse. The Magnum is the top of the company’s line; it provides much more working space than other Halls models because the structures are eight feet wide and available in three different lengths. Perhaps the most interesting feature of the Magnum is the inclusion of a box section ridge bar and cast joints at the ridge and eaves, which raise the height of the eaves nearly a foot above that of other Halls greenhouses.
Magnum greenhouses may not fit into smaller allotments or yards, but for those with the extra space, there’s a lot to like.
Size and Detailing: As mentioned, there are three sizes of the Halls Magnum: 8 x 10, 8 x 12 and 8 x 14. Each is big enough to allow four roof vents for maximum ventilation, and double sliding doors for easy access even if you’re bringing in large staging, a cart or a wheelbarrow. The extra size makes it possible for several people to work inside at the same time, and to grow a much larger number and variety of vegetables, plants and flowers. Gutters are also built directly into Magnum greenhouses.
Frames and Base: There are two choices for frames, either natural-colour milled aluminum, or the same aluminum with forest green paint. You can simply set the Magnum down with the frame effectively acting as the base of this greenhouse, or you can go for the optional galvanized steel base which is highly recommended, because the Magnum is a bit tricky. It has to fit exactly perfectly onto any external slab, concrete or brick base that you build for it, or it won’t sit properly. The steel base takes care of those problems, and is best utilized when fixed to the ground with concrete around the supplied anchors.
Glazing: All of the Halls Magnum greenhouses come standard with the traditional 3mm horticultural glass which is perfect for most situations. Safer and stronger options are available, however, including 3mm toughened glass which can withstand strong winds easily and will break into small pieces instead of large shards if cracked, and 4mm polycarbonate material which doesn’t do well in the wind but can handle almost any impact without breaking.
Options: When you’re going for the top-of-the-line greenhouse, you probably will want to take advantage of Hall’s large list of add-ons. Some of the most useful include five- and six-blade louvers manufactured with toughened glass, which will increase air flow in the glasshouse to prevent excess heat which can damage or kill plants, and stagnant air which can cause disease. They also have automatic vent and louvre openers which come in extremely handy. Other available options include downpipes which attach to the gutters on the Magnum, and a huge assortment of staging and shelves designed to match the look of your greenhouse.
Not everyone can fit a Halls Magnum into their garden, lot or property, and not everyone needs the extra space it provides. For those with the room and a particularly green thumb, however, the Magnum is pretty much everything you could ask for in a personal greenhouse.
