Polytunnels

Polytunnel Temperature Difference

Whether you have a polytunnel or not, there are certain things you should do to ensure that you grow the best plants possible. One of those things is knowing the difference between the temperature inside a polytunnel and outside.

Insulation

Using polytunnels for your garden is an effective way of extending the growing season and protecting plants. It is especially useful if you have a rainwater collection system. It is also a practical way of growing crops in winter.

The best way to protect plants from frost is by insulating your polytunnel. While there are different ways to insulate a polytunnel, one of the easiest is by using bubble wrap. This material is easy to install and remove and can be used to keep cold draughts out of the tunnel.

Another affordable method for insulating a polytunnel is by using straw mulch. This can be found easily in rural areas and keeps the area warmer on cold nights.

A thick cloud cover can also help to reduce the temperature difference between the outside and the inside of the polytunnel. In addition, the warmth of the sun can be transferred to the greenhouse through conduction.

Ventilation

Getting the proper ventilation in polytunnel is vital for keeping your crops healthy. Proper ventilation in polytunnel can prevent overheating and prevent the development of harmful algae and mold. In addition, regular cleaning of the polytunnel walls will make it a more enjoyable environment to work in.

You can also use a digital thermometer to monitor the temperature inside your polytunnel. This can help you decide when to sow or when you need to add extra protection.

To protect your plants from cold weather, you can use a heater in your polytunnel. This will keep your plants warm throughout the winter. However, this process can be expensive.

In warmer climates, you can grow your plants in an unheated polytunnel. In this case, the temperature inside the tunnel can reach as high as 85 degrees.

Watering

During a heat wave, it’s important to water polytunnels. Not only do the plants need moisture to stay cool, but they also need to stay well ventilated.

The soil in a tunnel warms up slowly. This is ideal for tender plants, but it does cause problems for other plants. A soil temperature of over 15 degrees Celsius can actually slow down germination and cause diseases.

Ideally, a temperature difference of at least 25 degrees is required to successfully grow most crops. In the case of tomato, a temperature of 90 F inside the polytunnel could stop the fruiting process.

Keeping the interior of the polytunnel well ventilated can help to reduce the number of plants with overheating problems. In addition, maintaining good ventilation is important for photosynthesis.

Plants to grow in a polytunnel

Whether you are interested in growing flowers, vegetables, herbs, or fruits, you have a few options. You can use a greenhouse or a polytunnel to provide a more sheltered environment for your plants. But how do you know which structure to choose?

In addition to protecting your plants from the elements, polytunnels can also be used to control climate. This includes temperature, humidity, and light levels. The use of supplemental lighting can produce desirable changes in the form of plant growth.

Depending on your location, you may want to heat your polytunnel in the winter. You can also consider a ground-source heat pump to draw heat energy from below ground. However, this option is more expensive.

If you live in a warmer region, you can also opt for an unheated polytunnel. This is a less costly and more practical choice.

Maintenance

Whether you’re on the lookout for a new houseplant or trying to snag the title of gardener of the year, a polytunnel is a smart choice. Not only are they cheaper to maintain, but they come with a plethora of perks. The latest offerings from manufacturers such as Greenworks and Suncast are geared toward a wide variety of horticultural needs. They can accommodate plants that require the perfect temperature conditions and the right amount of sunlight. They can also help prevent bugs and insects from spoiling your crops.

They can even be used to extend the growing season for your favorite plants. They’re also more versatile and have the potential to add some life to your home or office. There are several ways to keep your polytunnel in top shape, including the use of a quality polythene repair tape.
