General Greenhouse Buyer Advice

Customers often come to us after searching for "greenhouses for sale" without having an exact model or type in mind, after seeing the large selection we have on offer it is often difficult to narrow down your choices, this page will hopefully help you with your decision.

We only supply what we believe to be the best range of greenhouses available in the UK market, each manufacturer has been handpicked to offer the best value for money in relation to quality, there are lower cost greenhouses available from other sellers elsewhere, but we feel they will not give you a proper level of performance...if we did we would probably have them for sale ourselves!

We have a full greenhouse buyers guide here.

Below are some of the questions you should be considering

Metal or Wooden

Aluminium is the best choice for a metal greenhouse and will not rust or warp, almost maintenance free an Aluminium greenhouse will keep going on and on for decades, this versatile material allows for lots of different variations and a huge choice of sizes and options are available.
All Aluminium greenhouses are supplied in kit form so allow plenty of time to install, as a rough guide a 6x8 model will take approx 2 days with no previous experience.

We have a huge choice available from good sturdy entrance level models right up to super strong premium models.

See our range of Aluminium greenhouses here.

Wood is a fantastic material for a greenhouse and has a certain charm and warmth aluminium does not, simply being inside a timber greenhouse is a joy. We have carefully selected our range of timber greenhouses for sale for their build quality and ease of purchase, all our wooden greenhouse are hand made by UK craftsman and fully installed in the price! Each model is made with top quality materials with good thickness of timber.

Although we only supply what we believe are the best available, be aware that wooden greenhouses are not maintenance free and will need some aftercare if you wish them to keep going past the manufacturers warranties (at least 10 years). Wood greenhouses will also cost more than their aluminium counterparts.

Wooden greenhouse will often have the option to convert them into a greenhouse shed combo, which is very practical when you need a place to grow plants, alongside storage for tools. These are very similar to potting sheds.

All greenhouse types tend to have a traditional pitched roof.

Size

Deciding the size of your greenhouse is a big decision and one many customers are unsure of, you may be restricted to a size because of your garden or patio or you may have the luxury of being able to have one of the larger models available.

We suggest to actually mark out the area to see how the greenhouse will fit, try using stones or pots in the 4 corners or even better some stakes and string so you can really see the floor area.

Be aware that most Aluminium greenhouses are called by their nominal dimensions down to the nearest foot, in reality they are actually a few inches bigger, for example the most common 6x8 greenhouse (or 8x6) is actually 6ft4" x 8ft6" Every individual greenhouse page has a "Dimensions" tab with the exact size shown by diagram.

Try to think about what you are planning to use the greenhouse for, also be aware of future maintenance needed and possibly repairs...how would you replace a broken pane of glass if the greenhouse is up against a fence?

Some other popular sizes are 4x4, 6x10, 6x4, 6x6, 8x10, and 8x12.

Base Area

What are you planning on putting your greenhouse onto?

A hard-standing such as slabs, blocks, concrete would give you the perfect support for the life of your greenhouse, always screw your greenhouse to the base below no matter the size or quality.

A perimeter base around the outside where the greenhouse sits can allow you to grow in the soil inside, or perhaps a path up the middle with gravel or raised beds each side, a fully slabbed base throughout gives a nice clean environment and reduces the amount of bugs that will want to make your greenhouse their home.

Most Aluminium greenhouses will come with an integral or separate base that will allow you to put the greenhouse straight onto a prepared soil area, corner posts are provided so you can dig a hole and fill with concrete (Postcrete is a great easy cheap option available from most DIY shops), this is by far the most cost effective option and gives you the option to grow in soil or perhaps slabs or gravel inside so you are not standing on wet soil. Wooden greenhouses are not suitable for soil and have to go on a hard-standing.

Installation

Many of the Aluminium greenhouses have an installation option available in the dropdown boxes if you would prefer not to have to install yourself, if one is not showing we still may be able to help and welcome your call.

All the wooden models we sell have installation included.

Full instructions and fixings are provided with every Aluminium greenhouse and is a very achievable project for most people, no experience is needed and installing your own greenhouse can be very rewarding, our advice is to take your time and don't treat it as a race!

Glazing

Horticultural Glass

Horticultural Glass is the lowest priced glazing material, supplied in 2 foot square panes (or smaller) this does the job very well and can easily be obtained from local glaziers if you need to replace broken panes in the future.
The downside to Horticultural glass is that is breaks much easier than Toughened glass, the panes have sharp edges and because of their size they need to overlap each other, if a pane is broken it can break into dangerous shapes so is not suitable when children or less able people are around.

Toughened Glass

Toughened Glass is supplied in long panes (usually with a joining strip to allow for the triangle shapes) and has no overlaps, much stronger that Horticultural glass each pane has rounded edges so you will not cut yourself picking it up, all the Toughened glass we supply is British Standard safety glass that will granulate into small pieces greatly minimising the chance of injury.

Polycarbonate Glazing

Polycarbonate glazing is the ultimate in safety and has good insulation properties, the downsides are that it is semi-opaque (milky) and has little weight to it, polycarbonate panels will flex in the wind and can be blown out in windy conditions, we only recommend this option for sheltered positions. These are perfect for an alotment, or where you think there may be a high change of smashed panes.

These are sometimes known as a plastic greenhouse or a polycarbonate greenhouse.

Ventilation

Each model has at least one roof window (the larger the greenhouse more are supplied as standard), you can make these automatically open by temperature by adding an autovent to each window you want automatic, slatted louvres are available  lower down the sides of the building to add low airflow, these also can be made automatic by adding autolouvres.

Think carefully about the windows and louvres as it is very difficult to add these after installation, ideally a 6x8 would have 1 or 2 windows and 1 or 2 louvres, where as an 8x12 model would benefit from 2-4 roof windows and 1-4 louvres.if you are prepared to open the doors on hot days you may get away with less.

Warm air rises and is expelled through the roof windows, louvres draw in cooler air from outside the greenhouse which then has the benefit of circulating the air inside, each greenhouse will have recommended autovents/autolouvres for sale that will fit correctly.

Staging & Shelving

Assuming normal use you will be doing all sorts of potting and planting in your greenhouse, you will need staging or benches to work on, and places for storing all your tools and equipment.

Each greenhouse has its own recommended staging/shelving, some are free-standing while others are a strong cantilever design that fix to the frame. Every greenhouse page has full photo's and explanations of the dropdown boxes.

Accessories

Every greenhouse has lots of options to customise it to your preferred specifications, lots of accessories are available which will all fit that exact greenhouse in the drop down boxes...whether you want a heater or thermometer we have got you covered!

We like to think there is nobody more experienced than ourselves to help you choose the exact greenhouse you require...we welcome any questions!
