Halls Magnum Green 8 x 12 ft Greenhouse

(4.9) Based on 5 Reviews

Description

The Halls forest green Magnum 8ft x 12ft greenhouse is the mid-size model within the range, offering a natural green finished frame and 9.9sqm of internal growing space.

It's crafted from a strong, aluminium frame, that has been finished with an extra powder-coated layer, in a forest green colour. Not only does this add an extra layer of protection from weathering and the elements, but also lets it blend in more naturally with its garden surroundings.

The use of cast iron joints ensures that this 12ft deep structure is completely safe and secure, along with the option to upgrade to safer glazing alternatives of toughened or polycarbonate glazing if you require. Although, the standard horticultural glass is perfectly fine for when there are no children or pets to consider.

Its double doors provide you with a wide access entry point, allowing clear access for wheelchairs, and plenty of room for your wheelbarrow. Extra ridge height adds in added dimension and height, providing you with greater headroom for the development of your taller plants, and taller gardeners!

Greenhouses in the Magnum range are renowned for their robust construction and a high ridge, you won't fail to be impressed by this splendid greenhouse!

How To Install A Halls Greenhouse

Select Your Options

Customisation > Glazing

with Horticultural Glazing

with Horticultural Glazing (70892)

Standard 3mm glass which consists mostly of 2ft by 2ft panes, overlapping each other with the use of clips to hold one above another. This type of glass is traditional and very economical but tends to shatter into shards when smashed, so isn't recommended if you have children or pets.

  • Save £79.01
with Long Pane Toughened Glazing

with Long Pane Toughened Glazing (70893)

Long pane 3mm toughened glass is a lot stronger, and more durable than standard horticultural glass. In the rare event of it shattering, it breaks into safer smaller pieces. It is also neater and needs less maintenance as no overlapping glass means there is no algae build up and no Z clips to fit.
  • 6% Off
  • Save £99.01
with Polycarbonate Glazing

with Polycarbonate Glazing (70903)

Polycarbonate is a virtually unbreakable material, better described as being a highly durable, 6mm thick twin-wall, opaque coloured plastic glaze rather than actual glass. This makes it the safest material where children and pets are concerned and the simplest type to install due to the large yet lighter panes. It also refracts the light very well.

Excellent Product

Erected this ourselves and with hindsight, probably a project slightly too big for us. However, our son was available to help through furlough, and it is up, and ready to be glazed. Instruction photos would be more helpful if clearer and greater contrast, and a little more in depth instruction would be useful in areas like window construction, inserting extra bolts for use at a later point in the process (e.g. the windows and the bar that goes in below them). Also can the rubber be put in place prior to assembly - for example doing the roof after assembly is quite a stretch on a ladder on our 12 x 8. These improvements would all be very useful and ease frustrations especially during a very hot period of weather.

Excellent Product - Excellent Service

A really, really nice greenhouse, well made and all went together as it should. We've had a couple of guys working working on our major rebuild project for almost two years and they started life many years ago erecting greenhouses for a company. They put this green Magnum up for us and were impressed with everything - no missing bits, no parts that don't fit - in fact none of the problems you so often get with items such as this. Given that we ordered just as Corvid forced the country to a standstill, we had delivery (with a very helpful delivery driver - on time and really careful )not too far outside the normal period, so well done to all concerned. All in all a very nice experience all round and it looks brilliant. Thank You!

Magnum Greenhouse

Was delivered while I was out because there was no message of delivery date. Very nice and well made greenhouse, looks great now it is installed, but it took me a few weeks because of the bad weather and being away for a while. The photos in the manual could be a bit sharper and larger because they are difficult to see clearly and there needs to be more information on fitting to a concrete base without the Halls metal base. I am very pleased with it and would recommend this company to others. I found two panes of glass cracked and Halls refunded the money for the replacements.

Magnum Greenhouse

Greenhouse was delivered last Thursday and left on the drive as we had not received a message regarding delivery and were out. Following a telephone call to Halls who were very apologetic on behalf of the transporters and offer us some greenhouse staging in way of compensation. Halls were very professional when contacted, I would not hesitate to recommend them
