So if you’ve limited space outdoors, lean to greenhouses could be the ideal solution to your growing needs. Available in a choice of sizes to suit every garden, they provide essential protection from the elements and uncertain weather conditions, ensuring your plants get off to the best of starts.

What are lean to mini greenhouses?

A popular alternative to a free-standing greenhouse, a small lean to mini greenhouse is a compact structure which leans and fixes onto a wall, as the name suggests. This can be a suitably stable garden wall, the side of a garage or, more commonly, the exterior wall of a house.

Lean to greenhouses can be constructed from plastic or, for far more rigidity, glass sitting in an aluminium frame. They are made up of two gable ends, a sloping roof and a front section with sliding panels for access.

The benefits of lean to greenhouses

As we’ve mentioned, our space saving small lean to greenhouses are ideal for gardeners with limited space. But there are plenty of other benefits to be gained from installing a mini lean to greenhouse in your garden.

  • Heat absorbed by the wall during the day is slowly released in the evening, helping to maintain constant temperature.
  • Cultivate seedlings in the spring and prepare them for hardening off at a stable temperature.
  • Overwinter plants and protect them from the extremities of the unpredictable British weather.
  • Heat generated via the rear wall means there will be no sudden drop in temperature when night falls.
  • As plants can make the most of the sun’s warmth, growing times can be extended throughout the year.
  • Insect damage and the use of pesticides are reduced as undesirable pests will not have direct access to your plants.
  • If money is a consideration, a small lean to greenhouse is less expensive than a freestanding greenhouse to buy, heat and maintain.

Features of our classic lean to greenhouses

All our mini lean to greenhouses are manufactured in the UK using frames made from architectural grade aluminium which have a 25 year guarantee.

This classic lean to greenhouse model comes with 4mm toughened safety glass as standard, the same glass which is used for domestic double glazing units. This provides superior heat resistance and durability, especially when compared to cheap plastic panels.

The front door panels of our small lean to greenhouses slide for easy access and infinitely variable ventilation, and an adjustable shelving system means you can accommodate a variety of crops.

If you want to convert your classic lean to a free-standing greenhouse, glass backs are also available.

Mini greenhouse Accessories and Spares

We’ve a wide range of Mini greenhouse accessories for the Classic Range to allow it to be customised to your needs.

  • Shade Covers clip on the outside of the Classic Mini greenhouse to reduce the amount of light entering. Ideal for sunny locations and more delicate crops.
  • Louvre vents open and close automatically to ventilate the frame on warmer days. Beneficial early in the season when you need to completely close the Mini greenhouse at night.
  • Shelf covers allow smaller pots to be placed on the tubular metal shelves.
  • As for Classic Mini greenhouse spares, we’ve everything from channel liners and replacement parts right down to nuts and bolts. We’ve also replacement glass, although, for peace of mind, you could take out our two-year accidental glass breakage cover.
  • All our Classic Mini greenhouses can be colour coated in a choice of seven attractive colours.

Your lean to mini greenhouse through the seasons

Spring

Spring

During springtime, mini lean to greenhouses are ideal for growing seedlings, with more than adequate light and warmth to ensure successful hardening off.

Summer

Summer

When the warmer weather arrives, the removable shelves of our classic lean to greenhouse means you can grow Mediterranean varieties with more height, such as chillies or tomatoes.

Autumn

Autumn

In this season of somewhat unpredictable weather, cuttings and young plants will be protected from cooler temperatures, mild frosts and gusty winds in your small lean to greenhouse.

Winter

Winter

Lean to greenhouses are an excellent environment in which to protect plants as the temperatures fall below freezing, while shielding them from the season’s rain, wind and snow. A small heater can be added to provide frost protection.

FAQs

  • What’s the difference between lean to greenhouses and normal greenhouses?

    As opposed to free-standing greenhouses, small lean to greenhouses have no glass at the back as they are designed to be placed against an outside wall. So they only have three sides and not four. But there is no difference to what can be grown in either.

  • What are the benefits of a Lean to Greenhouse?

    One of the main benefits of a lean-to greenhouse as opposed to a freestanding greenhouse is the warmth provided by the wall.

    Glass traps heat, so in the daytime the greenhouse will warm up once the sun is on it. The bricks or concrete will absorb this heat during the day and then give it off in the evening – extending the growing day and also reducing the drop in temperatures over night.

    With a south facing wall, this effect is especially marked, particularly early in the season.

    If you do not have a wall, if the greenhouse is screwed to something solid, then this will generally still be warmer than a glass back.

  • How do you attach a lean to greenhouse to a wall?

    Our small lean to greenhouses can be easily fixed to a wall using the stainless steel screws provided.

    However, if the wall you have in mind is far from level, do take a look at our guide to fixing a lean to greenhouse to an uneven wall.

  • Do you need to anchor a lean to greenhouse?

    As they are fixed to a wall using stainless steel screws, our classic small lean to greenhouses are extremely stable, even in high winds. However, in windy conditions, do remember to ensure all of the glass panels are slid shut.

  • Can you put a lean to greenhouse against a fence?

    For reasons of both safety and practicality, we would not recommend putting a small lean to greenhouse against a fence, unless that fence is extremely sturdy.

    Plus, if fitted to a fence your lean to greenhouse will not benefit from the additional warmth generated by brick or stonework.

    If no suitable wall is available, there’s always the option to add one of our glass backs and transform your small lean into a free-standing greenhouse.

  • How do you build a lean to greenhouse?

    Like a lot of lean to greenhouses kits, ours are self-assembly. We’ll provide everything you need to easily construct your small lean to greenhouse, plus clear and comprehensive step-by-step instructions.

    If you’re unsure about any aspect of assembly, all you have to do is give us a call and we’ll be only too happy to help.

  • Do I need planning permission for a lean to greenhouse?

    Due to their small size, and the fact that they can be classed as a temporary structure, it is highly unlikely that your mini lean to greenhouse will require planning permission.

    However, as regulations differ from council to council, you may want to contact your local authority for full clarification.

  • How do I heat a small lean to greenhouse?

    Although there will be plenty of heat radiated from the rear wall, you may want to consider adding additional warmth in the coldest of months, or if you are growing a crop which is particularly susceptible to low temperatures.

    Our guide to insulating a small lean to greenhouse covers all you need to know.

  • What direction should a lean to greenhouse face?

    The simple answer to this question is where it will receive plenty of sun, allowing you to obtain the maximum amount of heat radiating from the rear wall.

    However, in whatever direction your small lean to greenhouse is facing, there’ll be plenty of crops and plants that will thrive. For example, a north-facing lean to will be ideal for shade loving plants and decorative foliage.

  • What should I grow in a lean to greenhouse?

    The versatility of a small lean to greenhouse means that there is very little which can’t be grown in one. The only limit is the size and height of your intended crop, obviously.

    As well as the ideal environment to start off seedlings and harden off young plants, you could choose any number of flowers, herbs and vegetables, from tomatoes and chillies to courgettes and winter lettuce.

  • What’s the difference between our classic and value mini lean to greenhouses?

    While constructed to the same high standards, our competitively-priced value range of lean to greenhouses are something of a ‘no frills option’ without many of the extras included in our classic range.

    Although these extras, such as watering systems and centre staging, can be purchased for an additional cost.

    And while the classic mini lean to greenhouses have 4mm glass, value ones use 3mm, although both use toughened safety glass.

    Likewise, value lean-tos do not have handles which run the full length of the glass, and their shelves have round bars instead of the strong square ones used for classic shelving.
