Polytunnels are an excellent way to grow crops in cold climates. However, they require a solid foundation and stronger supports. This will ensure that your polytunnel will stay put even in strong winds. You can use concrete for the tunnel foundation and door frames to ensure that they stay firmly in place.
Build a polytunnel with Northern Polytunnels
When planning to build a polytunnel, you need to take several things into consideration, including weather conditions. Polytunnels should have basic protection from frost and should be heated during winter. Another consideration is water supply. Many plants require copious amounts of water, which can be time-consuming. You should also consider the climate of your area as some plants will do better in cooler climates.
To erect your polytunnel, you must first prepare the site. You should start by digging a trench parallel to the long sides of the polytunnel. You should also angle it inwards to meet the door posts. Next, you should extend the trench over the front and cut the doorway.
They are easy to build
If you are looking for polytunnels for sale, you should look for a brand that’s easy to assemble. Some brands may have easy-to-follow instructions and videos. Others may be more complex, so you should make sure you are well-versed in the techniques you’ll be using.
First, you will need to build a foundation for the polytunnel. It is important to make sure that the base positions are square to each other and evenly spaced. To do this, drill holes that are about 3 feet deep.
They require a foundation
When installing a polytunnel, make sure that you install it on a level ground where it will receive a lot of sun. It is also a good idea to position the polytunnel in an east-west direction to allow for the best possible light penetration. You should also avoid placing the polytunnel under any trees as they can grow over time and cause problems with the structure. In addition, be sure to plan for proper movement of your equipment around the site. Large permanent polytunnels can be difficult to move around.
A polytunnel is stable only when it has a foundation. A foundation is essential in order to prevent the tunnel from moving or becoming unstable in strong winds. A foundation tube should be at least 6 feet long and driven three feet into the ground.
They have better ventilation
Proper ventilation is a critical aspect of polytunnels. It reduces the risk of disease, which spreads easily in high humidity. In addition to reducing disease, adequate ventilation can also increase crop yield and quality. Haygrove Growing Systems Managing Director Richard Mills cites four reasons why ventilation is important in polytunnels. The most commonly understood reason is temperature control, but the impact of humidity control is even more significant.
Polytunnels are ideal for growing plants that are difficult to grow outdoors. Although most of these plants are annuals, many perennials do well in polytunnels. In addition, vegetables such as asparagus and globe artichokes will grow better in a polytunnel than in the garden. Plus, you’ll find you can use these vegetables in more recipes if they’re grown in a polytunnel.
They last between one and two years
Polytunnels can be as long as 20 years if they are well looked after, but the polythene covering may only last for one or two years. If you want to maximize the lifespan of your polytunnel, you should consider the type of cover and the environment where it will be placed. A high quality cover made of 720 gauge polythene can withstand the elements for up to eight years. It is also possible to purchase covers with UV protection additives.
Proper ventilation is essential to the longevity of your polytunnel. Keeping it properly ventilated will help protect your crops from disease and pest infestation. It is also important to maintain an even temperature. A too humid environment will breed disease and pests, so it is essential to monitor humidity levels. You should also avoid over-watering to avoid damaging the polytunnel.
