Select Your Options
Option 1 > Greenhouse Glass
Three types of glazing are available for your greenhouse. Choose from standard horticultural, long pane toughened or 6mm polycarbonate options which let you customise your greenhouse to suit your needs.
Glass diagram images below are for demonstration of the glazing styles and may differ depending on your chosen greenhouse model.
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.
with Long Pane Toughened Glazing (70893)
Long pane 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.
with 4mm TwinWall Polycarbonate Glazing (70903)
Polycarbonate is a virtually unbreakable material, better described as being a highly durable, 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.
Option 2 > Base Plinth?
All greenhouses need to be fitted onto a secure base. This can be achieved by using an official Halls branded metal base plinth to give the greenhouse added strength and height. Alternatively you can build a brick base to fit your greenhouse size if you prefer.
Please Note: If you're having your greenhouse installed by the Halls team, you will need to purchase this base along with your greenhouse.
with Green Base Plinth (SO8319)
Add a matching steel base plinth to your order.
Image for demonstration only and base colour/style may vary depending on your chosen model.
Image for demonstration only and base colour/style may vary depending on your chosen model.
Option 3 > Ventilation?
Ventilation is essential for any Greenhouse no matter the size to ensure that the humidity and temperature inside provides the best growing experience for your new plants.
with Matching Louvre Window
A Halls louvre window with matching glazing. Louvre windows replace one or more standard glass panes to aid with ventilation in the side of your greenhouse.
Note: Louvre blades may differ between 5 or 6 blades depending on the greenhouse model. Image for demonstration only.
with Automatic Louvre Window Opener (70959)
When used in conjunction with a Halls Louvre Window, this device can be pre-set to open the window as and when needed when the temperature reaches a certain degree.

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
