PLANED SHIPLAP CLADDING: These greenhouses feature smooth planed fully interlocking tongued and grooved shiplap wall cladding. This design ensures that rainwater drains faster and the timber dries quicker, which ensures a longer life for your greenhouse. Our shiplap is fully tongued and grooved which is stronger than the half lap shiplap or rebated shiplap used by some others.

GREENHOUSE LOCATION: Ideally your greenhouse should have a clear space at least 18" wide on all sides, if possible. This ensures easy access for both installation and future maintenance. In reality this is often not practical and at many sites it is not needed. A reduced clearance is often possible on one or two sides. You should cut back or remove any nearby shrubs and trees. Remember to allow for future growth. Ideally the ridge of a greenhouse should run from east to west. The best position for a freestanding greenhouse is a sunny spot outside the shadow of nearby buildings and trees. A sheltered position is best otherwise additional screening may be advisable. Styrene glazing is not recommended at exposed sites. Plants need plenty of water so your greenhouse should be close to a water supply and the site should be well drained.

SIZES - LENGTH AND WIDTH: The sizes are listed alongside the price. The first dimension listed is the width and the second dimension is the length. The width refers to the angled gable walls at the front and rear including the door wall. The length refers to the side walls. The sizes listed are the external wall sizes. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger.

VENTILATION: Improved ventilation increases the air circulation through the greenhouse for better growing results. Automatic openers react to heat which ensures that in hot weather the vents open in your absence and then close again when its cooler. Some plants such as alpines require more ventilation than others. If you are not yet sure which plants you are likely to grow improved ventilation will give you more versatility.

HEATERS: We offer a huge range of heaters so whatever your specific requirements we have a heater to do the job. Our electric heaters require a standard domestic 13 amp electricity supply. Our propane gas heaters require permanent trickle ventilation when in use. As an approximate guide, a 3kw heater will heat a greenhouse up to 8'x12' or provide frost protection only up to 10'x15' in normal site conditions. A 1.5kw heater will normally heat a greenhouse up to 6'x8' or provide frost protection only up to 6'x12'. Internal partitions are often used in large greenhouses to create a smaller warm room which is cheaper and easier to heat.

HEATING REQUIREMENTS: Heating requirements vary for several reasons. Location is one factor with more heating required in Scotland than in southern England and less heating required in a sheltered position. The design is also a factor. For example, dwarf walls improve the insulation and lean to greenhouses absorb warmth from the existing wall. Another factor is the materials used. Polycarbonate greenhouses retain heat better than glass and wooden greenhouses retain heat better than metal greenhouses. We recommend you to buy a bigger heater than you need - you can always turn it down.

RECYCLED PLASTIC BASE KITS: Designed to spread weight and capable of supporting 300 tonnes per square metre, these durable and eco friendly plastic pavers are made from 100% recycled polypropylene. Lightweight and easy to install, extensive preparation is not normally required. A fully paved base has no soil inside the greenhouse. A perimeter base features a single row of pavers laid around the perimeter of the greenhouse with soil inside. The kit includes weed control membrane which is laid below the pavers. First the ground is levelled and then the membrane is laid directly on the soil. The pavers are laid on the membrane. Each paver features multiple locking clips which connect within seconds for greater rigidity. The pavers should be backfilled with pea shingle which is not supplied. Approximately 20kg of shingle is required per paver. Where space permits the base is normally laid full size but if required in a tight location the pavers can be easily cut to size without loss of structural integrity. Each paver is 500mm x 500mm and 40mm thick. These heavy duty pavers are only available when you purchase a Summer greenhouse. Fast delivery within 3-5 days ensures that you can start work quickly.
