A polytunnel is an inexpensive, flexible and highly effective way to grow vegetables. But it’s also less effective at controlling temperature. So, which is better? Read on to find out. It’s also cheaper and easier to erect.
Less effective at controlling temperature
Temperature can be a major concern in polytunnels. They can get considerably warmer than outside temperatures, causing crop damage. To counteract this, it is important to increase ventilation through the structure. Changing the polythene used to cover the structure can also help keep the temperature more manageable.
EMS technology, on the other hand, is aimed at temperate growing regions, primarily those in hardiness zones 7 or lower. These structures must be able to control temperature and ventilation, as well as above and below-ground heating. However, there are numerous advantages to poly tunnel farming. It reduces greenhouse gas emissions, and helps grow produce closer to markets. It can also help farmers adapt to changing climates.
Polytunnels can be constructed from wood or aluminum. Wooden structures are more durable and will last a long time. However, aluminum frames will bend and break more easily in poor weather. Wooden polytunnels can also last for many years, but you must be sure to protect them.
Polytunnels can help you grow early crops in the spring and winter. Spring cabbages and peas can be grown in a polytunnel. It can also help you grow spring salads and beans. By planting the seeds over the winter, you can start harvesting the vegetables in the spring.
Polytunnels are a great alternative to greenhouses, and they are considerably cheaper. For a start, a basic 2.5m x 2m polytunnel can be purchased for less than PS50 delivered. This is equivalent to an 8ft x 6ft greenhouse and is much cheaper than the average greenhouse.
A polytunnel costs less than a greenhouse, and it also requires less maintenance. However, timber framed greenhouses require regular paintwork and putty replacement. The choice between a polytunnel and a greenhouse depends on your circumstances and the type of crops you plan to grow. If you only have a small garden, a greenhouse might be the better option. Otherwise, a polytunnel may be a better choice if you plan to grow crops for commercial or personal use.
When choosing between a polytunnel and a greenhouse, there are several factors that you should consider. One important factor is the size of the structure. A smaller structure can be moved easily and costs less, while a larger one can house more plants and produce more yield. You can always expand the structure size if you find that your crops are exceeding your expectations. Another important factor is the design of the structure. A polytunnel can be built to look good and last for decades.
Whether or not your polytunnel will last for many years depends on the materials that make up the framework. A polytunnel can be made of aluminum or wood. Aluminum is easier to work with and does not corrode, unlike steel. However, aluminum is not as durable as other materials, and it can break or bend more easily in rough weather. Wood is another option, but it must be treated to resist oxidation.
Easier to erect
Compared to a greenhouse, a polytunnel is easier to assemble and dismantle. These structures are typically made of plastic sheeting stretched over aluminum arches. They are often tunnel-shaped, but can also be dome-like or tent-like. They can be erected in virtually any location, unlike a greenhouse, which needs a firm flat foundation.
A polytunnel can get much warmer than the outside temperature, which makes it ideal for growing plants in warmer climates. However, proper ventilation is necessary to control the temperature. By raising the sides and widening entrances, you can increase air flow, which prevents condensation and mould.
A polytunnel can be as large as thirty feet or ninety feet. It is important to know how big you want your polytunnel to be in order to grow as much as possible. The size should be based on the number of plants you are growing.
More suited to growing larger amounts of fruit and vegetables
Polytunnels are a flexible way to grow vegetables and fruit. They are more cost-effective than greenhouses and can be moved around if you want to change your crops. They are also easier to maintain, with lower maintenance costs per square meter. Polytunnels are ideal for growing virtually anything, from small vegetables and fruit to large fruit and vegetable crops. However, you must bear in mind that they may not be suitable for fruit trees and thorny plants.
A polytunnel can be installed in just a day and costs less than a greenhouse. The disadvantages of a polytunnel are condensation and light transmission issues. However, the advantages of a polytunnel over a greenhouse far outweigh these disadvantages.
