Buying Guide

Are you looking for tips for your new Greenhouse? Have a look at an article we wrote about Greenhouse Gardening Tips.

A greenhouse can be a major expense depending upon its structure, build, size and every other feature. For a small garden, a large greenhouse can be nothing but a mismatch. Since there are different aspects that one must consider while buying a new greenhouse for the garden, the process of choosing the best greenhouse may seem a little difficult.

Location – A greenhouse should be placed in a location that gets maximum sunlight. There should be enough space around a greenhouse so that the sunlight doesn’t get blocked by some structure or a large tree. The ideal base for a greenhouse is a flat surface and hence, it’s essential to level the site before placing a greenhouse. Water sources and electricity should be easily accessible from the greenhouse.

Structure – There are various types of greenhouses that differ from one another based on their structure or design. Here are some popular structures that one can choose from.

  • Lean-To Greenhouse: This type of greenhouse is ideal when there is limited space. Lean-to greenhouses work excellently in retaining heat when facing south. Both the glazing and the walls attract a lot of heat and keep the plants warm in this greenhouse. Some lean-to greenhouses come with internal doors which ensure convenient access.
  • Freestanding Greenhouse: As the name suggests, this type of greenhouse doesn’t need any wall to lean on. It is ideal when there is enough space in the garden. Freestanding greenhouses come in various designs such as barn-style roofing, curved glazing and circular designs. Though heating may differ in these designs, all of them ensure enough space for staging plants.

Build – The framing of the greenhouse plays a vital role when it comes to ensuring quality and durability. The most common frames are wood and metal.

  • Wooden Frames: Wood is the most convenient choice for gardeners as it lasts quite a long time. The best quality wooden frames must have insulation properties, which means that they will keep the greenhouse warm in winter and cool in summer. Wood can be the most expensive option for the first time but in the long run, the expenses are minimal. Timber and Thermo Wood are some great options.
  • Metal Frames: It is the best alternative to wood and is easy to transport. Metal frames are comparatively less expensive than wooden ones, which is their biggest advantage. Aluminium can be an ideal choice among all metals as it is rustproof, long resistant and lightweight. It is essential to look for powder-coated aluminium frames as they won’t dull off after a few months.
  • The build of the greenhouse is equally important as the framing. While there can be multiple options, glass and polycarbonate are the most common ones.
  • Glass Build: Glass greenhouses are very common and these are the highest quality ones among all types of greenhouses. Glass being the heaviest material is not easy to transport and is prone to shattering. Glass is more expensive and durable than polycarbonate if it’s shatter-proof.
  • Polycarbonate Build: Expense-wise, it is cheaper than glass. It works as a good alternative to glass because it has excellent heat retention properties. However, since polycarbonate is semi-transparent, it might not be the best option when a gardener wants to display the plants.

Size – Depending upon the space of the garden and the number of plants to cultivate, the size of the greenhouse should be decided. The gardeners need to ensure that there is enough headroom inside the greenhouse as they need to work inside. For an average-sized garden, an 8 Inch x 6 Inch greenhouse can be ideal. The price of a greenhouse can vary depending upon its size.

Heating – Another essential element of a greenhouse is heating. It is important because a gardener needs to keep plants warm on colder nights. Here are some common options:

  • Gas: It is a convenient option for family greenhouses that require heating. It gives the highest temperature when compared to the other options. Butane and propane are the best options among gas heaters. The downside is the harmful fumes of gas heating.
  • Electricity: It is perhaps the most reliable option because electric heating can be controlled easily via a thermostat. Fan heaters are very common in greenhouses that ensure uniformed heat control. The downside is the dependency on electricity.
  • Paraffin: Though it is the most cost-effective option during the purchase, re-fuelling and maintenance can be expensive. Other downsides are condensation, humidity and fumes.

Cooling – Cooling down the greenhouse during summer is a genuine concern among gardeners. Ventilation is the easiest way and it can be done in two ways – naturally and by using a fan.

  • Natural Ventilation: A greenhouse should have side vents and roof vents to ensure proper ventilation. For freestanding greenhouses, there should be vent openings on the sidewalls and the ridge. The proportions of the sidewalls and ridge vents should be equal.
  • Fan Ventilation: There are fans available to cool down greenhouses on summer days. Maintenance is essential when choosing fan ventilation as most of the fans require an electric connection. To save energy and circulate air evenly, staging fans would be the best idea.

Lighting – Materials that ensure proper lighting during the day are horticultural glass and safety glass. Though polycarbonate does an excellent job of retaining heat, it is not the best option for lighting.

During the night, there should be enough lighting to provide a heating solution to the plants. A greenhouse should come with mounts and slots for placing lights.
