Polytunnel Winter Temperature

Polytunnel Winter Temperature

The winter temperature in a polytunnel can be difficult to predict, but there are a few things you can do to ensure the plants inside stay safe and healthy. First, consider what you can do to reduce the amount of heat coming into the polytunnel. You can use insulation or ventilation, horticultural fleece or shade.

Insulation

The best way to reduce the winter temperature inside your polytunnel is to insulate it. This can be done by using bubble wrap and fastening it to the tunnel using string or cable ties. When choosing bubble wrap, it is best to buy one that is UV stabilised and extra durable.

The main advantage of polytunnels is that they can grow crops throughout the winter months. The best way to prevent your plants from suffering from the winter temperature is to make sure that the polytunnel is insulated. Most polytunnels are made from double layers of polythene that is reinforced with nylon mesh. This makes them more durable and insulated. These types of polytunnels are more expensive than ordinary polytunnels, but will protect your crops better. The disadvantage of double layers of polythene is that they won’t allow for as much light as regular polytunnels do.

Shade

For a polytunnel to be successful, it needs to be well prepared for a range of temperatures. The ideal temperature for most plants is between 26 and 30 degrees Celsius, although temperatures can rise considerably during sunny days. Too much heat can affect the growth of plants, impede germination, and cause problems with photosynthesis. In extreme cases, overheating can even result in the death of plants.

To reduce temperatures, cover polytunnel walls and roof with net shades. These nets can provide 47% of the shade your plants need, while still allowing for full ventilation. They can be fixed to the polytunnel’s roof with cable ties. You can also create a damp path around the polytunnel to keep the air moist, which will discourage pests.

Horticultural fleece

If you’re concerned about the winter temperatures in your Polytunnel, it’s a good idea to invest in horticultural fleece. This super-insulating material can help protect tender young shoots from late frosts and can also help boost the soil temperature. It’s an easy-to-use fabric that’s lightweight and permeable. Moreover, it can last for up to three or four years when properly treated. It will also extend your growing season by about two or three weeks.

While the Winter is a less busy gardening season, polytunnels help you keep your crops growing throughout the winter and into spring. This way, you can enjoy the bounty of the crop even on cold days. It is also a great idea to invest in a heater for your Polytunnel. Whether you’d prefer a traditional or modern one, First Tunnels has several options for you.

Plants to grow in a polytunnel in winter

Although there are many advantages to growing certain crops in a polytunnel, some crops are only suitable for the winter months. Garlic is a good example of a crop that does very well in a polytunnel. Planting garlic indoors in October will allow it to sprout quickly and grow over the winter months. This means that when it comes to harvesting, your crop will be three times larger than what you would have grown in the winter outdoors. Another advantage of growing your garlic indoors is that it will extend the growing season by 4-6 weeks. You can then start harvesting your crops a few weeks later than you would have had you grown it outside.

Another great choice for wintertime growing is kale. This weather-hardy vegetable is easy to grow and you can sow it directly into the soil in your polytunnel. Carrots are also excellent for growing in a polytunnel in winter because they can survive in cool temperatures. Carrots should be planted at least 10cm apart and should be kept moist.

Costs

Polytunnels are useful for a range of purposes, from livestock housing to horticulture. They provide a controlled environment for plants to grow in, and they are an ideal solution for greenhouse gardening. Polytunnels are relatively inexpensive, and they can be constructed using any materials you choose. Compared to traditional methods of growing plants, polytunnels have more advantages than disadvantages.

The cost of a polytunnel depends on the material you choose and the size of the structure. A simpler polytunnel can be bought for about sixty dollars (250x200x200cm), but more expensive ones will cost you more.

Sizes

There are many different sizes of polytunnel, and if you want to protect your crops from the winter cold, you should consider the size of the polytunnel you choose. The right size will help you protect your plants from the weather, and it will allow you to grow more crops in the autumn, winter, and early spring. Polytunnels are also great for protecting your plants from the ultraviolet rays of the sun. They have galvanised metal frames for strength, and a plastic sheeting cover for protection. Although polytunnels are great for protecting your plants from the cold, you should also keep in mind that they can be quite hot inside, so it is important to choose a size that matches your climate.

In order to prevent your plants from suffering from the freezing winter temperatures, you should buy insulated polytunnels. This will allow you to grow crops throughout the winter and prevent them from dying. Often, these polytunnels have two layers of polythene, and these are reinforced with nylon mesh to keep the heat inside. You’ll find these polytunnels to be more expensive than regular polytunnels, and they won’t let you get as much light.
