From what vegetables are ideal for polytunnels to learning the proper temperature range, this blog has it all for every farmer and gardener in the United Kingdom.

What Is The Best Growing Temperature For Vegetables In A Greenhouse

What Vegetables Do Well In A Polytunnel?

Gardening specialists in the UK will tell you that growing vegetables in the polytunnel may be a challenge, but you can get through with this very easily. Take good note that the best vegetables to cultivate in the polytunnel are those you can consume and sell to the market. They must be able also to thrive indoors. 

The best vegetables to have include:

  • Peppers
  • Strawberries
  • Lettuce
  • Tomatoes
  • Beans
  • Peas
  • Cucumbers

What Is The Best Growing Temperature For Vegetables In A Polytunnel?

The best temperature that must be within your polytunnel is 85 degrees Fahrenheit, so regulating the temperature should be the first lesson you must know as you keep the temperature stable within your polytunnel.

Proper ventilation is also crucial when taking care of your plants, as what plant specialists can share. The polytunnel can offer the ideal environment, but it remains a duty for you to keep the correct temperature levels in the area.

Many of these polytunnels are present to source the energy from the sun as you heat the air inside, though there are supplemental heat sources you can have with electric or gas heaters. Like your automobile, the interior of the building may quickly heat up to over 100 degrees Fahrenheit on warm, sunny days, so regulating the temperature is necessary to avoid the plants to suffer. 

Polytunnels should also have vents, as you have heard of earlier, either the top vent that opens a hatch right in the ceiling or side vents, as well as fans that whisk out hot air and welcome cooler air. You can prefer vents that either operate automatically or manually. 

The manual systems are more affordable, but remember to constantly open and shut your vents during the day as you close them during the night. Some individuals may consider this extra work, and for those who are not at home by the day, it may be an issue, significantly when the weather suddenly changes. 

Take note that automatic ventilation systems work on sensors that kick on the fans or heating systems if the temperature rises or falls below limitations in the system. It should be similar to how your house heating and cooling system exists. 

Can You Grow Vegetables In A Polytunnel Year-Round?

The polytunnel is a preferred addition to your vegetable plantation, enabling gardeners in the UK to make the most of the sunlight. Even the smallest, unheated structures can let UK gardeners extend the seasons with the polytunnel as they produce the best crops for a wide range of vegetables.

The best polytunnels are those you can use most times of the year. Heated greenhouses will allow for maximum use all year round, but rarely they will be cost-effective. 

Late winter toward early spring

Be sure to sow hardy plants, including cabbage, celeriac, early leeks, Brussels sprouts, lettuce, onions, and peas, for planting out when the warmer weather has arrived. You may utilise your heated propagator to ensure the proper germination.

Heated polytunnels may have peppers, tomatoes, and more tender plants that you can sow early with the propagator.

Middle of spring

While one may use a polytunnel all year round, and this is a guarantee that we offer, sowing fast-growing tender plants like cucumbers, pumpkins, squashes, and courgettes are best during mid-spring. You may also add French beans, sweetcorn, and melons. Up until late in the spring or early in the summer, they will grow best. You can also utilise the heated propagator to ensure germination.

It is also a good tip to purchase ready-to-grow pepper and tomato plants to introduce in unheated polytunnels. You may start sowing basil indoors, ready to get moved outside during the summer. 

Late in the spring to early in the summer season

What you can do is to cultivate summer polytunnel plants into the final positions indoors. Then, you may also harden off and plant out young plants for your outdoor crops once frost has passed. 

The middle of summer

The mid-summer UK gardener’s dream must have them harvesting crops like melon, French bean, and cucumber. They may also include parsley and calabrese when summer crops have ended.

Late in the summer

When your spaces permit, late in the summer season, what you can do is to sow lettuces, spicy leaves for your salad, baby carrots, and more before the autumn sun. You can also, right now, start planting new potatoes for the Christmas season using the heated polytunnels


In the autumn, remove the spent summer vegetables as you plant out lettuces into beds and grow bags ready for winter harvesting. You may also plant calabrese, French beans, and parsley prepared to get the seedlings mature indoors. 

After this, you may slow broad beans and peas to overwinter and plant out once the clay soil becomes more manageable early in the spring season. Sow hardy lettuces and pea shoots to harvest these indoors during the spring. Finally, move your herbs in pots and keep them cropping longer. Things will get better when you take heed of these steps.

What Temperature Should A Polytunnel Be At Night?

Consider that the temperature must be at 32 degrees Celsius (90 degrees Fahrenheit) and 24 degrees Fahrenheit (75 degrees Fahrenheit) at night. This polytunnel temperature for your vegetables should also depend on the crop growing at either cooler or lower temperatures to produce the ideal results. Plants may have more branches and flower buds compared with plants in warmer conditions.

What Temperature Is Too Cold For A Polytunnel?

Having the right temperature is downright necessary. At the minimum, the heated polytunnel must be free from frosts at 37 degrees Fahrenheit. Still, tender plants like citrus trees, half-hardy fuchsias and pelargoniums must have happier outcomes with minimum temperature at 45 degrees Fahrenheit, safest at 50 degrees Fahrenheit. 

How Can I Heat My Polytunnel For Free In The Winter?

To answer this thought, here are the steps to follow. Finding opportunities to heat the polytunnel without paying the cost could be challenging, but there are cheap alternatives to make this happen. 

The cost of heating the polytunnel during the winter may be greater than the savings, as well as the advantages of having one on your own. Thus, it is excellent to use the mini polytunnel, have a rabbit hutch in the space, install composting hay, or dustbins to save up on the costs.

How To Make A Comfortable Bed Without A Mattress? 5 Best Ways

How to make a comfortable bed without a mattress? We all want a comfortable and complete bed when we sleep.

However, buying a mattress could be a hassle, and maintaining one isn’t an easy thing to do, too.

It’s a whole responsibility, and I know none of us likes doing these tedious tasks!

Therefore, I thought, what if we try to make our beds and exclude the mattress itself?

Luckily, I found out that there are four best ways to make a comfortable bed without a mattress.

It includes using airbeds, futon mats, sleeping bags, camping mats, and creating a DIY mattress-less bed.

Finding the best bed without the hassle is an easy thing to do for yourself. Keep on reading to know more!


Ways To Make A Comfortable Bed Without A Mattress

So, how to make a comfortable bed without a mattress?

You could create a comfortable bed without a mattress by looking at these five main options:


#1. Airbeds

The first option that comes in this list is airbeds. These are portable, easy-to-build “mattresses” that are unlike mattresses at all!

Airbeds are inflatable beds that provide you with the comfort and a good quality sleep as any standard mattress would.

One thing that’s also great about airbeds is that they’re easy to disassemble.

You can fold and stack them once you’re done sleeping which makes it less of a hassle!

You don’t need to worry about maintaining them, too.

Purchase an airbed and assemble it using this guide.


#2. Futon mats

Futon mats are thin, foldable versions of your typical mattress. These tend to be smaller and are often used on the floor.

The Japanese created futons, and these beddings are still being used now.

These beddings are often layered with cotton or any soft fabric that feels like a typical mattress.

Moreover, futons also provide you with better posture in the long term since it aligns your back well compared to a bed.

Due to their small size, futons also provide you with more space within your room.

These mats could be easily rolled and stacked after use, making them an excellent alternative for a bulky mattress.

You can buy futons almost everywhere, from your local stores to online shops, your option is endless!


#3. Sleeping bags

Don’t have the luxury to purchase any of the said items above? Here is an option that is just for you.

Sleeping bags are sleeping items that you can find in almost every household.

These beddings are the epitome of minimalism and are also great for making a comfortable bed without a mattress.

These beddings are soft, warm, and are portable. We can use sleeping bags anywhere and any time since thin duvet sheets can be folded and disassembled.

You can put these sleeping bags on your bed frame or even sleep on the floor with them!

Beddings like these also help strengthen your back in the long term by keeping your back straight and sturdy instead of using a soft mattress.


#4. Camping mats

Still don’t want any of the stated options? Here is a bed option that could be just for you.

Camping mats are an excellent substitute for a mattress and could make a comfortable bed.

Typical camping mats are equipped with insulation technology which keeps your back warm from the cold air throughout the night.

The main advantages of these beddings are thin and easy-to-carry; you can stack them up quickly after using them!

Furthermore, camping mats are also soft and very durable since they are designed for camping, but these mats make for an excellent mattress substitute, too.


#5. DIY mattress-less bed

The final option for a mattress-less yet comfortable bed is for you to create your very own. I know this may sound like a tedious task, but it isn’t!

I have discovered that “sandwiching” or stacking a comforter, pillows, and a thin blanket in that exact order!

The comforter would act as an insulator for the bottommost part, and the pads provide softness like that of a standard mattress.

A significant advantage of these DIY beds is that they are easy to assemble and can be made by anyone!

These beddings also provide you with the perfect feel that is not too soft nor too hard, which can give you a great night’s sleep.

All you need to do is buy the said beddings and stack them up!

You can even sew them up by putting them in the exact order and sewing the comforter and blanket together.

It’s easy, cheap, and very comfortable too!
