When To Use A Growing Light In A Polytunnel? 2 Proved Advice!

It cannot be obvious when to use a growing light in a polytunnel, so remember that it’s when the existing light intensity is not optimal and if the growing plants need it. The Auburn University Office of Sustainability has mentioned that one of the advantages of polytunnels is that you can have complete control of the environmental conditions. And one of these conditions relies on artificial light, so you must know how to use it correctly in the UK. 

Gone are the days when farmers have to worry about extreme and unpredictable weather in the United Kingdom because polytunnels allow productivity all year round, including tripling crop yields. However, it’s essential to learn the requirements of your plants to guarantee this impressive success. Below is a guide on when to use a growing light in a polytunnel.

Supplementation needed

We all know that plants need light to perform photosynthesis, so a successful polytunnel should provide this in addition to other optimal conditions. According to Cornell Information Technologies, natural sunlight is sometimes enough for the polytunnel. But in some cases, this leads to problems in temperature that can affect the plants negatively. 

As a result, polytunnels use cooling systems and reduce the light levels to control the temperature. The temperature control can then potentially lead to another problem, which is the lack of light. In this case, you want to provide a growing light to support the plants

Another example that dictates when to use an organic light in a polytunnel is during the winter months. In the Northeastern and Northwestern parts of the UK, the cloudy conditions affect the amount of light in the polytunnel. The lack of light during certain seasons is where using a growing light is going to be necessary. 


Young plants vs mature plants

From the name itself, a growing light is something you’ll use for the polytunnel to support your plants’ optimum growth. However, it’s worth remembering that different plants and vegetables vary in their requirements for growth. Michigan State University even mentioned that light plays a role in the fruit yield of plants

Once your seedlings germinate, you’ll notice the effect of the light levels on their growth. If the growing plant does not receive enough light, it will end up weak with thin stems. And even if it survives to mature, the stem will not thicken. 

As your plants grow, you may need to use a higher growing light intensity to ensure that even the older leaves receive light as much as the new ones. Simultaneously, the type of plants you’re growing will also affect the need for a growing light in a polytunnel. For example, you will need a growing light for plants moving into the fruiting or flowering phase during the months with little natural light. 

In the United Kingdom, you will need to use a growing light to support tomato production because it usually happens at the end of October. On the contrary, some plants grown for vegetative parts may not need a growing light since they stay at this growth stage anyway. Still, low light levels during winter may require you to have a growing light to prevent plant growth from slowing down. 

How Long Should You Use A Growing Light In A Polytunnels?

As mentioned previously, the light requirements for each plant vary. Therefore, using a growing light in a polytunnel will depend on the plants you have. You can classify your plants in long-day and short-day groups to make the planning of growing light duration easier.

Long-day plants will grow best and undergo the reproductive phase when the day is long, while short-day plants would be better if the night is longer. The difference in growth speed is why some plants will start to flower even in the autumn. And since short-day plants like herbs are grown for their vegetative phase, you can use an organic light to extend the day length. 

Overall, the success of your polytunnel is affected by the light it can provide. It’s crucial to know your crops’ individual lighting needs while also being mindful of the other requirements they need to thrive. At the same time, it’s worth noting that failure to meet the proper spacing on your crops can also affect the amount of light. 


Can You Have Too Much Light In A Polytunnel?

You must maintain the optimal lighting conditions in the polytunnel because too much light also equates to high heat energy that can affect the plants. The proper balance of light conditions is where the ratio of light and temperature is vital in a successful polytunnel. For temperature control due to too much light in the polytunnel, you can use cooling systems, evaporative cooling, and shadings. 



A successful polytunnel depends on the planning and execution of each crop’s optimal growing conditions and requirements. Knowing when to use a growing light in a polytunnel is one of them, so note that it’s when the existing light intensity is not optimal and if the growing plants need it. Each plant and growth phase may require a specific depth and duration of growth in the UK, which means careful planning and preparation are mandatory.

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!
