Greenhouse buyers’ guide
If you have never tried your hand at gardening or count yourself as an expert, buying a greenhouse can revolutionise the growth of your plants and vegetables. Through our handy guide, we’ll help you navigate the world of greenhouses and assist you in choosing the best greenhouse for your needs.
If you’re wondering what to grow, where to position your greenhouse, what material to use, or even the temperature to keep your greenhouse, then read on. Following our advice, you will be well on your way to creating a thriving greenhouse environment and a home for your gardening exploits.
What should you look for when buying a greenhouse?
When buying a greenhouse, there are several features to consider to ensure that you choose the right one for your needs.
- Size: One important feature to look for is the size of the greenhouse, as this will determine how much space you have to grow your plants.
- Materials: You will also want to consider the materials used in the construction of the greenhouse and how well-ventilated the greenhouse will be, as proper airflow is crucial for healthy plant growth.
- What you’re growing: You might also want to consider what you plan on growing, what your budget is, and how often you will use the greenhouse.
What can you grow in a greenhouse?
A greenhouse provides a controlled environment that allows you to grow a wide variety of plants, including fruits, vegetables, flowers, and herbs. These plants may not thrive in the UK climate, so a greenhouse can be used to replicate foreign weather conditions.
Of the fruits that you can grow in a greenhouse, the most popular selections are often tomatoes, cucumbers, strawberries, raspberries, and melons. Vegetables such as lettuce, spinach, peppers, and beans also grow well in a greenhouse.
For flowers, options include roses, chrysanthemums, and orchids. Particularly for those who opt for a miniature greenhouse, herbs are often chosen as the selected grow. Basil, parsley, and mint can all flourish in a greenhouse environment.
What is the best temperature for your greenhouse?
The ideal temperature for a greenhouse depends on the types of plants you are growing, as different plants have different temperature requirements. However, as a general rule, the ideal temperature range for most greenhouse plants is between 18-24C during the day and 13-18C at night. In higher temperatures, it is advised by experts at the Royal Horticultural Society to keep your greenhouse below 27C.
During the colder winter months, a minimum temperature of 7-10C should be maintained to prevent damage to plants. It's important to note that proper ventilation is also essential for regulating temperature and preventing heat build-up, which can be damaging.
What is the best material for your greenhouse?
When it comes to choosing the best material for a greenhouse, there are several options to consider. Some of the most common materials for a greenhouse include glass, polycarbonate, and PVC.
The windows of the greenhouse always allow light in, so are made of more transparent material. Wood, steel, and other metals are then favoured for the greenhouse’s frame.
This is a newer material that has become popular in recent years. It is lightweight, strong, and shatter-resistant, making it a great choice for areas with high wind or harsher weather conditions. Polycarbonate also provides good insulation and can help to reduce energy costs. However, it may scratch easily and can yellow over time.
PVC is another plastic, its full name is Polyvinyl Chloride, and it is lightweight, durable, and resistant to weathering. Its properties make it suitable for use in a variety of climates, but it may not be as strong and sturdy as other materials, like polycarbonate. In extreme weather conditions, this could mean it breaks more easily or blows away.
Glass is one of the most traditional materials used for centuries in greenhouse construction. It is durable, long-lasting, and provides excellent light transmission. However, it is also heavy, breakable, and expensive. Difficulty shipping glass means that, in recent times, plastic alternatives have been championed by gardeners and retailers.
Wood-framed greenhouses are often aesthetically pleasing, and with wood being natural and renewable, it is an eco-friendly choice. Wood has good insulation and durability and can withstand harsh weather conditions. The main drawback of wood-framed greenhouses is their susceptibility to rot and decay. Wood can also be affected by moisture and insects.
Steel and aluminium frames
Greenhouses with metal frames are durable and strong but often less aesthetically pleasing than wood. The materials are low maintenance but relatively expensive compared to other options, such as wood or PVC frames. Rust is the main problem of both metals, and this can be especially problematic in areas with high humidity or near saltwater, where rust can occur more quickly.
Where to position your greenhouse?
The position of your greenhouse is an important consideration, as it can affect how well your plants grow. You need to consider several factors when setting up your greenhouse.
- Space: Before buying a greenhouse, you should check the dimensions and see if it can fit into your garden, patio, allotment, or even inside your home. When you have made sure of this, you can consider the below factors.
- Sunlight: Your greenhouse should receive plenty of sunlight throughout the day to help aid the growth of your plants. Position your greenhouse in a place that receives maximum sunlight, especially during the morning and early afternoon hours.
- Wind: Choose a location that is sheltered from strong winds, as this can cause damage to your greenhouse and plants. Depending on the weight of your greenhouse, you should look to weigh down the sides in the event of a storm or bad weather.
- Access: You should make sure your greenhouse is easily accessible as it is important you can check on your plants, water them, and take them in and out of the structure.
