If you are thinking about building a greenhouse or polytunnel for your gardening needs, this article will help you decide which one is right for you. This article will also cover the costs of greenhouses and polytunnels. In the end, you will be able to build the perfect greenhouse or polytunnel for the needs of your garden.
Building a polytunnel
To build a polytunnel, you need to start by constructing the frame. The frame can be made from aluminum tubing, mains water pipe or scaffolding poles. These should be driven into the ground at least three feet deep. When you drive the poles into the ground, use a block of wood to level the tube. Once you’ve anchored the frame, the next step is to attach the polythene cover.
Polytunnels should face the wind. Ideally, they shouldn’t be too close to trees. You also need to leave at least one meter of space around the perimeter so that construction is easier.
Choosing between a polytunnel and a greenhouse
Both greenhouses and polytunnels are useful structures for growing plants and crops. Both provide ventilation and ideal growing conditions, but which is best depends on your specific circumstances. For example, if you have limited space, a greenhouse is probably more suitable. Alternatively, if you want to grow a large variety of flowers, vegetables, or herbs, a polytunnel will be more appropriate.
One big difference between greenhouses and polytunnels is cost. A greenhouse is usually more expensive and permanent, but a polytunnel is more flexible and cheaper to buy and install.
Cost of building a polytunnel
If you’re planning on building a polytunnel, it’s important to know how much it will cost to build. Generally, polytunnels cost less than greenhouses. However, they are suited for growing larger plants and tend to have issues with condensation and light transmission.
A polytunnel is typically made of two long garden beds with some extra space between them. Most polytunnels are designed to grow vegetables, such as tomatoes and cucumbers. They are often equipped with a nursery table and a space to grow seedlings. A polytunnel can also have a walkway, so gardeners can avoid muddy shoes.
Polytunnels are great for extending your growing season. You can grow plants in them from spring to fall. However, you have to keep in mind that they can block 23 to 9 percent of natural light. Hence, it is best to avoid installing them in Zone 1 or Zone 2. In addition, a polytunnel is an ideal location for a homestead garden, as it will be a one to two-minute walk from your kitchen.
Cost of building a greenhouse
There are many factors to consider when calculating the cost of building a greenhouse. The size of your greenhouse, climate controls, plants, and other systems will all affect the cost. The more complicated the greenhouse, the more money you’ll have to spend up front. Also consider the time and labor needed to clear the plot of land. This is a labor-intensive process, so you may want to hire a professional or rent earth-moving equipment.
If you’d like to add a glass greenhouse, make sure to get bids from construction companies. These professionals can help you choose the most appropriate materials for the greenhouse frame. They can also help you source cheap glass. Secondhand glass is often cheaper than new plastic varieties. Another consideration is the type of flooring you’ll need. You can use a wood floor or a dirt floor. A wood floor requires some sort of leveling and installation, and may require a staking process.
Alternative materials for building a polytunnel
If you’re trying to save money and build a polytunnel, you may want to consider alternative materials. Concrete, for example, is inexpensive and sturdy, and can serve as the foundation for your tunnel. You can also use old floorboards for the perimeter of your tunnel. Just be sure to use wood screws to secure everything together.
You can also make your polytunnel out of wood, which is also a popular alternative. Wood is strong and can last for several years when built properly, but it is important to protect it from the elements.
