Magnum greenhouses from Halls are the perfect fit for any grow your own enthusiast. Strong aluminium frames assembled using cast iron joints ensure that each spacious structure is completely safe and durable. Its double doors provide you with a clear entry point, offering great access for wheelchairs, as well as plenty of room for your wheelbarrow and tools. 

Taller grows will be thankful for the extra ridge height of the overall frame, as well as providing greater vertical height for the development and growing of taller plants, such as tomatoes and green beans. 

Before you choose your Halls magnum greenhouse, ensure that you have checked the available space - as the Magnum greenhouse comes in 3 sizes, it's always best to double-check that you're not buying one too small. Where possible, it's best to go for the largest sizes to fill your available space for maximum growing space and cost-effectiveness per foot of greenhouse. 

All Magnum greenhouses come with three glazing options to choose from, either horticultural glass, toughened glass, or polycarbonate glazing.

Self Assembly Tips

Setting up your Halls magnum greenhouse at home is not difficult, but in general, can take between 6-8 hours depending on greenhouse size. When choosing a spot in the garden to site your greenhouse, ideally, pick an area with maximum sunlight, and the greatest protection from the wind.

Never over-tighten the bolts initially as a little 'play' in the frame can be an advantage later. Make sure all the bolts are fully tightened to complete the installation. We normally recommend progressively tightening opposite bolts, as you would on a car wheel.

Fully illustrated instructions are enclosed, complete with guidelines for safe handling. Halls also provide an extensive range of stylish accessories, each one designed to enhance your Halls greenhouse and improve your growing results.
