How Can You Keep Your Polytunnel Warm at Night?

There are several ways to keep your polytunnel warm during the nighttime. Here are some of the simplest yet most effective steps you can take:


Add compost in your polytunnel

Compost is naturally warm, so it makes sense to keep them inside your polytunnel. Good compost can be as hot as 100 degrees F. It can keep your polytunnel warm throughout the night, especially if you regularly turn it to add oxygen. Additionally, having wood mulch as pathways can contribute to the heat.


Use thermal mass objects

If you solely rely on the sunlight to heat your polytunnel, you need thermal mass objects to increase warmth further. Bricks, clay, rocks, concrete slab floor – these objects absorb heat during warm weather and release it when the atmosphere is cold.

Using thermal mass objects is one of the most affordable ways to heat a polytunnel. If you’re planning to make raised beds, use stone or bricks for maximum heat absorption. Water is an excellent thermal mass as well. It’s also a great idea to put black barrels or water around your polytunnel.


Strategically position your heaters

If you have heating systems, make sure to put them in an open spot at a corner of your polytunnel. Keep them away from water for safety purposes. Additionally, angle the heater above the plants that need it most.


Only heat the necessary areas

You don’t have to heat your entire polytunnel if you don’t need to. You can create a mini polytunnel inside your polytunnel. Further insulate your mini polytunnel by placing bubble wrap, your heating system, or horticultural fleece.

Why Should You Buy a Mini Polytunnel?

A mini polytunnel is an excellent investment for anyone interested in polytunnel gardening. It’s a cheaper and more convenient alternative to a regular-sized polytunnel. If you still haven’t decided, here a few reasons why mini polytunnels an excellent investment:


Start early plant growth

With a mini polytunnel, you can start planting even before the cold season begins in your region. You can plant warm-season vegetables in your polytunnel, and as the weather gets warmer, you can transfer your plants into your British garden. In this way, you’ll be able to harvest crops earlier than usual so that you can start your next planting season earlier.


Compact and easy to handle

If you think that all polytunnels are as big as a small house, think again. Polytunnels come in all shapes and sizes. Mini polytunnels, in particular, are compact and convenient for home gardeners in the UK who don’t need a big and spacious greenhouse. A mini polytunnel is more cost-effective, and it gives you the same benefits as a regular polytunnel.


Protect your plants from pests and animals

While there are beneficial insects, there are also bugs that want to eat your leaves and produce. Raccoons, rodents, snails, aphids, and other animals and insects can damage your months of hard work. Additionally, if your plants are out in the open, they’re more prone to catch certain diseases from neighbouring plants. Keeping them inside a polytunnel keeps them safe from pests, animals, and diseases.


Great for UK gardeners with limited space

If you’re interested in growing crops but don’t have enough space, a mini polytunnel is a perfect solution. You can plant almost anything inside a mini polytunnel regardless of the weather outside. Plus, you can place it anywhere – on balconies, patios, decks, and even on your tables. The average size of a mini polytunnel is around six ft., but there are smaller options for those who like a more compact size.


Keep plants safe from bad weather

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!
