Which Is Best Polytunnel Or Greenhouse

When it comes to choosing a greenhouse or polytunnel, there are several factors to consider. You may want to look for one with more storage space, or a larger structure with more planting space. However, remember that you will need to consider the price of the structure as well.


The most common way to ventilate a polytunnel or conservatory is by opening a door. However, if there’s only one door, this is insufficient to provide adequate ventilation. If your polytunnel is more than 30 feet long, side windows and roll-up vents can be very useful. The problem with these ventilation systems is that they can also allow insects and other pests to enter.

Proper ventilation is crucial to your plants’ health. By providing ample ventilation, you can reduce the risk of diseases, such as leaf mould. Humidity encourages the growth of moulds and mildew, which can lead to disease and damage. Inadequate ventilation can also promote the growth of pests and diseases.

Proper ventilation in a polytunnel can help extend your growing season, which can be essential for growing certain crops. Proper ventilation will help to keep the greenhouse at a consistent temperature and ensure that your crops don’t suffer from a lack of moisture. Furthermore, a proper ventilation system will help to reduce condensation and mould in your polytunnel or greenhouse.


Durability of a polytunnel or greenhouse depends on the materials used in its construction. A polytunnel is usually made from polythene, which comes in a variety of types and qualities. The polythene should be 720 gauge, or 180 microns thick, to ensure longevity. A good quality polythene cover should last at least five years, and in some cases up to ten years.

The construction of a polytunnel or greenhouse is easy to do, and the frame is generally sturdy enough to last decades. Polytunnels, however, are more prone to damage in high winds, and errant branches can damage or break the glass. In addition to durability, a greenhouse is easier to maintain than a polytunnel, which will require periodic repairs.

A polytunnel or greenhouse can be built for short-term or long-term use. Small versions can be purchased for a fraction of the price of a large polytunnel, but if you want to preserve your polytunnel or greenhouse for many years, then you should invest more money. The cost of a polytunnel can range from fifty to several thousand dollars. The price range varies depending on the size and construction.


When comparing the cost of a polytunnel and a greenhouse, there are several factors to consider. Although greenhouses are more expensive, polytunnels are considerably cheaper, and they are less susceptible to damage. In addition, polytunnels require minimal maintenance. Most polytunnels have a lifetime of about five to ten years, so you can expect minimal upkeep over this time.

A greenhouse is usually easier to insulate, and it can be fitted with shelving and staging. A polytunnel does not have staging, which is an essential feature for a growing garden. Adding extra height is useful for gaining heat and light, and it is much easier to install staging in a greenhouse than in a polytunnel. Fortunately, wires can be used to tie plants to scaffolding.

A greenhouse is also more durable and will last for longer. Polytunnels are flexible and easy to erect, while greenhouses have toughened glass and require careful site preparation. Both structures are beneficial to the growing process, but one may be better suited for a smaller growing space.

Whether to buy

There are many advantages to having a greenhouse or polytunnel in your garden. These structures offer optimal growing conditions for plants and can increase the length of your growing season. These structures are also ideal for starting seeds and growing plants from seed. Both greenhouses and polytunnels are relatively inexpensive, and they are easy to expand if you need to grow more plants.

You can save a lot of money by buying a secondhand greenhouse or polytunnel. However, keep in mind that used tunnels will require dismantling and reassembling. These structures may need new plastic and a wood door. The hoops may also need to be replaced. Also, make sure you check the structure for rotting wood or bent aluminium.

Polytunnels are easier to maintain than greenhouses. They are made of polythene, rather than glass, so they can be easily repaired. However, glass panels in greenhouses are more expensive to replace than polythene ones.
