How Can You Lower the Temperature of a Polytunnel

If your polytunnel is too hot, here are some of the ways to lower the temperature:


Open the doors and windows

Let yourpolytunnelbreathe. Open the doors and windows or roll up the plastic sheet to release to ventilate and provide air circulation.


Use fans

Using fans to cool down your polytunnel is better than opening doors and windows. Fans keep the hot air out and draw the fresh air in. For this method to be effective, make sure not to place the fans on the ceiling or ground level. You should place the fans around six feet high in front of vents to draw air over and through your plants.


Use shade

Another way to lower the temperature inside your polytunnel is to use shade. The use of a shade blocks the blazing heat from the sun from entering your polytunnel. You can use a shade cloth, plant vines, or a liquid shading compound.


What Grows Well in a Hot Polytunnel?

Temperatures go up during summer, so it’s better to grow plants that thrive best in warm weather. Just make sure they get plenty of water so they’ll continue producing throughout the summer. Here are the following plants you should consider growing:



Greens grow well in warm weather. But if you want to hasten growth and harvest, it’s best to plant them in a polytunnel.



To grow sweet melons, you’ll need two to three months of warm summer weather. Keep your plants moist, but make sure not to overwater, especially when the melons are starting to ripen. Adding too much water makes melons bland. Heirloom melons are deeply rooted in the soil, so they thrive best in heat and drought.



The hotter it gets, the faster the corn grows. However, you need to ensure that the soil is moist enough throughout the growing season. Corn absorbs a lot of water to form crunchy and sweet kernels.


Sweet Potatoes

While sweet potatoes are famous in the southern United Kingdom, northerners are beginning to catch up. Sweet potatoes thrive best in the heat, but they need to have even moisture, just like other plants. Don’t forget to harvest your sweet potatoes before the soil temperature goes below 55 degrees F.



Compared to sweet bell peppers, hot peppers work better under prolonged heat. If you prefer sweet peppers, you can try planting Big Bertha, Cal Wonder, Cubanelle, and Sweet Banana.

Top Reasons Why You Should Invest in a Polytunnel

Polytunnels allow you to control the climate. You can ventilate during hot days, protect your plants from heavy rains and strong winds, and provide shade under the blazing sun. At the same time, you can also maintain the humidity levels to ensure that your plants grow healthy.

Here are some of the reasons why you should invest in a polytunnel:


Prevent pests

Harmful pests and critters can destroy all your hard work. By placing your plants in an enclosed space, you can prevent birds, deer, moles, aphids, mites, etc., from attacking your plants. Consequently, you wouldn’t need to use toxic pesticides or chemicals to ward off these critters.


A longer growing season

Polytunnels offer a longer growing season since it provides a more controlled climate. The controlled climate enables you to plant weeks or months longer.


Protect plants from extreme weather

Placing your plants in a polytunnel protects them from harsh weather, such as heavy rain, strong winds, hail, storm, and blazing heat. As we’ve already established, polytunnels can shield the plants from the effects of temperature swings.

Strong winds and beaming sun rays can negatively affect the delicate plants if left exposed. Glass polytunnels or polytunnels with a plastic, translucent cover diffuse the sunlight that hits your plants while ensuring that there’s enough ventilation throughout the space. Make sure to use a polytunnel to cover your plants and produce from harsh weather.


More plants to choose from

If you want to grow plants that aren’t native to your UK area, you should consider getting a polytunnel. As mentioned, you can easily control the temperature in a polytunnel so that you can offer a colder or warmer environment regardless of the weather outside.

The heat and insulation let you plant warm-season crops even if it’s the winter season. A polytunnel allows you to adjust the climate based on the plants you want to grow. All you have to do is to understand the conditions your plants need to grow and thrive.


Thoughts on the Answer to “What Temperature is Too Hot for a Polytunnel?”

Now that you know what temperature is too hot for a polytunnel, make sure that your polytunnel’s temperature DOES NOT exceed 90 degrees F. Otherwise, your plants may shrivel up and die. Make sure that you know the perfect growing conditions for your plants and adjust your polytunnel accordingly.

What Is The Size Of A Baby Crib Mattress? Read This!

A baby is tiny, but then they also need to have a comfortable sleep since they are one sleepyhead, so, do you have any idea what is the size of a baby crib mattress?

Babies are sensitive; that’s why you should always keep an eye on them.

When it comes to mattresses, you want to find the material suitable for their skin providing comfort and support.

There are beddings with pillows sold as a package for babies.

In that way, you will be able to make sure that they have a good surface and support them when they are sleeping.

Having a soft mattress to lay them in makes their sleep a lot better.

It must be smooth and fluffy so that it would make the baby feel comfortable and sleepier.

Aside from drinking milk, another thing that babies do is cry and sleep.

As a mother, you would not want them to cry all the time.

It would mean too much stress both for the baby and for you.

So, without further ado, let’s discuss!


The Size Of A Baby Crib Mattress

A baby sometimes cries because of hunger, but it could also be uncomfortable and a strange feeling for them.

As I have said, babies are way sensitive. You must be very careful about choosing your things to avoid sudden reactions.

Putting the baby beside you on your mattress is fine, although it would be better to have their bed made for babies.

Mattresses should be soft and mild for the baby so choose wisely.

Include the thickness and, of course, the size of the bed.

But then what size is a standard baby crib mattress? There are a lot of beds found in every part of the world. It mesmerizes me to know about all this.

There are so many types of mattresses produced. It could be traditional, modern, convertible, etc. It is all up to you to choose from your preference.

So, what is the size of a baby crib mattress?

A crib mattress would usually be fifty–one and five – eights (51 5/8) up to 53 inches in length.

Including the width is about twenty-seven and one–fourth (27 ¼ ) up to 28 inches. And its thickness would be around 4 – 6 inches thick.

Familiarizing yourself with this is the right decision, especially when you are having a baby in no time.

A crib is one tool that could help you have some time for other things when your baby is asleep. You can just put them down there and let them rest for a while.

As a mom of an infant, you have no enough time for other things, and you focus on your baby. Babies are very dependent.

And that would mean having them by your side always.

You see, some babies, when uncomfortable with their sleep-wake up in no time.

You have to find the right mattress for them to put into so that their sleep won’t get disturbed, and you can also rest and sleep for a while.

Grab that crib and find the right mattress for it.


Is It Necessary To Buy A Mattress That Fits The Crib?

Well, indeed it is. Of course, it is necessary to buy a mattress that fits into your cribs.

Leaving spaces or gaps free could put your baby in danger.

Remember that your cribs could be their sleeping place up until they are 3 – 4 years old.

And that you have to consider things up to that period.

When a baby starts to crawl, walk or explore they would move more inside the crib.

And you should limit contact with the material as much as possible.

Some cribs have gaps in their structure that could trap up your babies. You have to avoid these situations from happening as much as possible.

And when talking about a mattress that is way bigger than your crib, it would still not go well.

You have to think of how it would like if it laid flat on the surface.

It would just fold upwards, which would affect the mattress’s structure and form.

It would be going up along the sides of the crib and would create a sweltering space.

Mattresses are thick, which could cause to give off some heat from it.

But then it is better that way than a bed blocking the sides.

It could result in a lack of air and could harm the baby. Just try to cut the mattress to the size of the crib’s surface as much as possible.

In an instance, to avoid this, you could learn how to measure your mattress to fit with the crib.

You can check this out, and you are good to go.



When you are carrying a baby inside you, you would want to give him/ her the best things you could when they come out. That includes a good sleeping bed or crib.

Now that we have answered your question, “What is the size of a baby crib mattress?”

I hope that you have an idea somehow and you can prepare for it.

Best wishes and have a good time with your babies!
