Greenhouse Buyer’s Guide

A greenhouse is a staple for most gardens and outdoor spaces, ensuring that light can envelop your plants, flowers, and vegetables, increasing the level of photosynthesis experienced, which in turn results in an increase in production. The moisture and heat emitted from the daytime climate are trapped inside of the greenhouse and allows the flowers and plants inside of the greenhouse to continue to stay warm during the colder nights.

Assembling Your Greenhouse

Before assembling your greenhouse, consider the surface which your greenhouse will be positioned on. Ensure that the surface is flat and free from any slopes as well as free from possible roots, which may result in future warping; for this reason, place your greenhouse away from any trees. A flat and level surface is beneficial for the stability of your greenhouse as well as the longevity of your plants, flowers, and vegetables.

Looking After Your Greenhouse

The temperature of your greenhouse is vitally important.  Monitoring the temperature inside of your greenhouse is a key task to complete at varying points of the day and the night for the benefit of your plants, vegetables, and flowers. Purchasing a thermometer is a good concept, enabling you to regularly check the temperature of the greenhouse and enabling you to make alterations where appropriate. If the temperature inside of the greenhouse rises too high, open the greenhouse door or the hatch to regulate the temperature and look after your plants, flowers, and vegetables effectively.

Furthermore, keep your greenhouse tidy with as much space as possible free, eliminating the possibility of creating areas for slugs and snails to hide in. Traditionally, glass was the most popular material used across numerous greenhouses, providing an aesthetically pleasing appearance that is strong and tough. However, glass as a material for a greenhouse does need to be replaced more often than other materials, and so can become a costly material to use.

Plastic is a less appealing choice aesthetically, although it is affordable and more commonly used. However, polycarbonate is a much more popular choice, providing more clarity than plastic yet it is still durable and affordable. Whichever material is used for your greenhouse, ensure that the structure is fitted correctly and properly to reduce the chance of mold developing.

Looking After Your Plants

Before placing your plants, or your flowers and vegetables, into a greenhouse, consider the needs of the plant. Perhaps a certain type of plant would benefit from a milder climate during the day, outside of the greenhouse, while enjoying a warmer temperature inside of the greenhouse during the colder night. A temperature that is consistently too high is of no benefit to some plants, flowers, and vegetables and so monitoring them regularly and regulating the temperature which they are exposed to is a good idea.

In addition, consider specific items for your greenhouse, which offers shade for your plants, such as Coolglass. An additional and proactive benefit for your plants is to water them during the evening as watering your plants during the hot temperatures of the daytime may lead to the water experiencing evaporation. Plants should also be covered with fleece during the nights where temperatures have dropped, with a cheap alternative being the use of bubble wrap.  Furthermore, check your greenhouse during the night for any slugs and snails before they have the chance to invade your plants.

The perfect temperature for your greenhouse is between 80 to 85 degrees Fahrenheit, as achieving higher than this temperature may result in causing harm and damage for your plants, flowers, and vegetables.  A good level of ventilation is also a necessity to allow air to circulate, reducing the chance of overheating as well as the chance of disease and mold developing.

Sunlight Requirements

If you are growing vegetables within your garden, they will require up to eight hours of direct sunlight every day to achieve their full growth and potential, being needy for sunlight and thirsty for the sun.  Examples of vegetables and fruits that require this level of sunlight include berries, tomatoes, melons, pumpkins, and peppers.  Root vegetables, such as the carrot, require much less sunlight than that of fruit, merely three or four hours per day.

Alternatively, leafy vegetables such as lettuce do not need a great deal of sunlight, and so you should monitor the intensity of sunlight experienced by these vegetables. If the sunlight is too intense, the taste of the leaves will be bitter, and so this should be avoided. Remember that too much sunlight is not always a positive aspect for your greenhouse, as overheating and an abundance of sunlight can cause some degree of harm to plants.

If your plants and vegetables are not receiving enough sunlight from your greenhouse, consider including artificial lighting such as grow lights.  Artificial lighting will ensure that your plants, vegetables, and flowers will receive a consistent amount and intensity of light, regardless of the weather conditions and the effects of nature. Research the types of artificial lights available for you and your needs before installation, as some types of artificial lights may harm your plants.

Furthermore, ventilation for your plants and flowers is a necessity and so open the doors and hatches of your greenhouse to allow a strong airflow. If your greenhouse does not experience sufficient airflow and ventilation, consider installing fans to provide what your plants, flowers, and vegetables require.

Consider Location

The location of your greenhouse is very important and will depend upon the amount and the intensity of sunlight experienced by your plants, flowers, and vegetables. Consider the hemisphere which you are located in, positioning your greenhouse across the north-south axis if you are located in the southern hemisphere. For colder climates positioned in the north, position your greenhouse on the east-west axis so that during the colder months of the winter season, your greenhouse will receive a greater amount of sunlight.

Expert Tip

To fully understand what is occurring inside of your greenhouse, purchase a thermometer and place the thermometer inside of the greenhouse so that you can continue to monitor the temperature at all times of the day throughout the seasons.

Did you know?

Before installing a greenhouse into your outdoor space, consider what you want to grow and the practicalities of your garden. Different plants and flowers will require different amounts of sunlight, different temperatures, and, therefore, different positions across your garden.
