Small Greenhouses

Small Greenhouses

Small Greenhouses allow the gardener with even the smallest of spaces, to get going and "grow your own" plants and vegetables at home.

Even with a small 2ft x 4ft lean-to greenhouse, you can grow lots of herbs, salad and vegetables throughout the year to make supermarket visits cheaper and benefit from fresh, pesticide free, organic produce. Growing your own is surprisingly easy. In fact, it's a habit that your whole family will benefit from. The children will learn that the food they find on their plates grows in compost, not on a shelf in a supermarket!

Small Greenhouses: Functional And Rewarding

It’s easy to be jealous of someone who owns a large, sprawling greenhouse, particularly when you only have a small garden or allotment to work with. There’s an alternative to simply wishing for more property while settling for purchased vegetables or flowers, though – small greenhouses are ideal for families who wish to grow their own fresh, organic produce.

For clarification, we define “small” glasshouses as structures which are between 2x4 and 6x6, whether they are small lean-tos or proper freestanding models. There are small greenhouses for sale which will fit nicely into even the smallest space or allotment, suitable for starting plants or seedlings to be transplanted outdoors, or for indoor gardening year-round which can be enjoyable and rewarding for the entire family.

Here’s a look at some of our small greenhouses which are attractive, functional and affordable.

Small Greenhouse Models

When you’re looking for small greenhouses to buy, naturally the most important consideration is the amount of room you have. The models we offer measure 2x4, 4x4, 4x6, 4x8, 6x6, 7x5 and 7x7, with the smallest being a compact lean-to and the larger ones being freestanding structures. All are from quality brand-name manufacturers and designed to stand up to long-term use. This is just a brief sample of the many choices we have available, to give you a feel for what you can expect to find.

Those with the tiniest spaces to work with are best served with a Vitavia 2x4 lean-to, perfect for use in small walled gardens, on balconies or on patios. The actual width of these models is 4 feet, 3 inches with a sloping roof that reaches a maximum height of 1840mm, allowing enough room for several full-sized plants or a large number of smaller ones. Two optional shelves can be added to provide even more growing space. The Vitavia lean-to is far from a wobbly, homemade structure; it has a frame made of anodised aluminium (available in green or silver) and an optional steel base, a sliding door and opening roof vent, and comes with your choice of 3mm horticultural or toughened glazing. All of that – creating your own personal indoor growing space – for well under £300.

The next step up brings us to smaller freestanding greenhouses, 4 x 4 or 4 x 6 in size. We offer a wide selection of high-end small greenhouse kits from top manufacturers like Elite, Halls, Eden and Palram, and as just one example we’ll take a closer peek at the Elite Compact 4 x 4.

This sturdy, good-looking structure, with its aluminium frame (available in many colours) and 3mm horticultural, toughened or polycarbonate glazing, will easily fit into just about any allotment or small garden. The Elite Compact also comes standard with locking, sliding double doors, an opening roof vent, a low-threshold base (for easy access) and integral rain gutters. The peaked roof is 2100mm tall, allowing plenty of workspace while you tend to the large assortment of plants which will fit inside, and the work area provides enough room for optional staging or shelving. Speaking of options, there’s a range of choices which you might only expect in larger glasshouses, including extra roof vents and side vents with automatic openers. The price of this outstanding glasshouse starts at well under £400, and 4x6 models are available as well from Elite and many other manufacturers.

If you’re fortunate enough to have a little extra space we have a terrific selection of small greenhouses for sale for gardens or yards with available footprints as large as 4x8 or 7x7. They include such versatile models as the Elite High Eave 6x6, the Rion EcoGrow Orion 6 x 6 with beautiful sloped eaves, and the gorgeous Swallow Kingfisher 6x6 Wooden Greenhouse with oversized glazing panels.

The structure we’ll look at a little more in depth, though, is the Vitavia Orion 6 x 6 glasshouse. This is a stunning small greenhouse for backyard applications (although it will also fit into many allotments) with stunning curved eaves made from ultra-violet protected acrylic panels, providing lots of extra room for high plants. You can choose from a silver- or green-coloured anodised aluminium frame, horticultural or toughened full-length glazing, extra opening roof vents (one comes standard with this model), and all sorts of extra staging or shelving to give you almost as much growing space as you would envision having in one of those large, sprawling structures you’ve dreamed of. The Orion also comes standard with integrated base corner posts (for additional strength) and gutters, and extra bracing for the roof and corners. For only a little over £500, this is one of the most cost-effective small greenhouses for sale in our collection, and can provide enough indoor growing room for you to have delicious, organic fruits and vegetables all year with plenty left over to give away or sell.

All of these small greenhouse kits are a snap to assemble – but what do you do with them once they’re in your garden? Here are some tips on getting started.

Getting the Most Out Of Your Small Greenhouse

It’s quite likely that if you’re looking at small greenhouses to buy, this will be your first foray into the world of indoor gardening. You may already have specific vegetables or plants in mind for your glasshouse; if not, we have a few suggestions. But first, there are several other factors to consider when setting up small greenhouses – 4 x 4, 7 x 7, or space-saving lean-tos.


Many will tell you that a glasshouse of any size should face east or west, to take advantage of full sunlight while still allowing for shade during part of the day. Lots of sun is optimal, of course, since that will save you from having to providing additional heat and because many crops like tomatoes and peppers need plenty of sun in order to ripen. However, if the location of your structure is constrained by available space or other buildings, there are also advantages to facing the greenhouse north (perfect for young plants which must be protected from scorching rays) or south (great spring sunshine, although some additional shading and ventilation will be needed). In a nutshell, your small greenhouse can face in any direction, as long as plenty of light is available and you take proper care to protect your plants.


The types of protection which are most important are shading and ventilation, since too much direct sunlight, and the heat and humidity that build up inside a greenhouse, can easily kill the plants you’ve worked so hard to grow. Some glasshouses feature twin-wall polycarbonate glazing, which is the best choice for insulation and UV protection, although it does somewhat limit the amount of sunlight transmitted through it. Other methods of protection are shade compound (a removable substance applied to the glazing) or shade curtains which are usually made from aluminised polyester. These will diffuse light and help to maintain a more even temperature inside the structure.

Adequate ventilation by means of roof or side vents, or simply by leaving a door open, is the other key consideration when setting up your glasshouse. The more vents you’re able to include in your greenhouse, the more control you will have over the heat and humidity in the growing space; automatic, louvered vents which operate based on indoor temperature are the best choice if they’re an option for you. Otherwise, you can open or close the greenhouse door to somewhat control airflow and climate, with a sliding door the easiest to adjust as needed.


One other consideration: the more space you have in which to place your plants, the more you’ll be able to grow. Staging or shelving is the best way to increase the “growing footprint” of your glasshouse; when considering small greenhouses for sale, be on the lookout for those which offer integral shelving or enough room to install extra staging.

Choosing Your Plants

The key to making the most use of a small greenhouse is careful planning, so you can make the best use of your space during each season. Here are some suggestions courtesy of the Royal Horticultural Society.

Winter and Early Spring: This is the perfect time to start young plants indoors, in order to transplant them outdoors when summer arrives. Hardy varieties like cabbage, lettuce, onions, Brussels sprouts, peas and leeks are perfect candidates. Only sow tender plants like tomatoes and peppers in a propagator if the glasshouse is heated.

Mid-Spring: Tender plants like squash, French beans, cucumbers, squash, sweetcorn and melons, and herbs like basil, can be sown. Small tomato and pepper plants that you’ve purchased can be acclimated to the greenhouse during this season.

Summer: Early in the season, harden off and move crops outdoors unless they’ll be remaining under glass, in which case they should be moved to their permanent positions in the greenhouse. Mid-season is the time to sow calabrese, parsley and French beans outdoors so they’ll be ready to come into the glasshouse in autumn. Late in the season, sow another crop of lettuce and carrots indoors for late harvests, and plant potatoes for Christmas if you have a heated glasshouse.

Autumn: Bring your crops of French beans, parsley and calabrese indoors, sow hardy lettuce and pea shoots, and begin sowing peas and broad beans to be ready to be moved outdoors in early spring.

Happy gardening!
