Help! My Polytunnel is Overheating

With global temperatures on the rise, you may find the temperature in your polytunnel is on the increase. It goes without saying that there are both advantages and disadvantages to our warmer temperatures.

You can look at temperature increases in different ways. If you feel like growing new exotic crops and plants you can do so. But!You should be aware that warmer temperatures can lead to other problems in your commercial polytunnels or garden polytunnels.

 

One of the biggest problems apart from wilting plants is insect infestations. Inspect your polytunnel every couple of days to make sure that no new pest insects have set up home in your tunnel.

What Polytunnel Supplies Should I Have on Standby?

 

You may already have a good quality insecticide on stand-by. But, if you find new types of pests in your tunnel, you may want to set up an alternative arsenal. Prevention is always better than cure. For instance, neem oil is often used and is disliked by most pests that prefer warmer temperatures. We have already mentioned neem oil on another article, but we think it is so good that we like to emphasise its use.

 

Shading should also be on your polytunnel supplies shopping list. You can buy different kinds of shading covers that are available for both garden polytunnels and commercial polytunnels. The shading does not have to be black. As a matter of fact, black attracts heat. Green shading is much better depending on your preferred crop. You may even be able to buy army surplus camouflage netting.

 

Water Supplies in Your Polytunnel

 

Water supplies are essential when the temperature starts going up. Constructing your own water irrigation system is not very difficult at all. Unless you have an exceptionally large polytunnel, you should be able to install a drip system in a day. We are going to take a look at how you can make your own drip watering system and save money in detail in another article.

 

Ventilation is another key factor that you must not overlook. You will find that most commercial polytunnels have a ventilation system installed to suit the intended crop. If you are not sure how to set up a ventilation system in your polytunnel, it is a good idea to get in touch with a polytunnel supplies company. They can help to install one, or sell you what you need.

 

Are Polytunnels Going to be a Thing of the Past?

 

With the temperature going up all of the time, many gardeners think that greenhouses and polytunnels will soon be a thing of the past. That is not true.

 

Both domestic and commercial polytunnels are going to play more of an essential when it comes to growing crops and plants. Polytunnel supplies will continue to adapt to our climatic changes, with new products becoming available.

 

Don't forget that polytunnels are there for protection as well as propagation. Choose the right set up and your polytunnel will protect your crops from harmful hot rays from the sun and winds that would normally dry out your garden or field crops.

 

In the future, we are likely to see more polytunnels springing up,as we combat the climate crisis.
