Frequently asked questions


1. How many seasons does it take the average grower to pay for a new polytunnel?

Most growers can more than cover the cost of their Polytunnel in just a single season. 

2. Do I need to get planning permission for my polytunnel?

As most Polytunnels use concrete foundations they are considered a permanent structure, Planning isn’t always required. But to be safe, check with your local planning officer or building inspector.

3. I want to stretch my growing season as much as possible; what would you suggest?

Start with a genuine polytunnel and extend your season 3-4 months. Then for extra growing weeks, add a second layer of insulating film and an inflation blower. Some growers even use floating row covers inside the polytunnel during the coldest months. 

4. How do I control the temperature in my Polytunnel?

The classic phrase “warmed by the sun and cooled by the winds” describes the natural temperature regulation process in our greenhouses. Even on cloudy days, the sun warms the interior of a polytunnel nicely. Roll up the sides or open the roof vents for ventilation; and a breeze will take care of the rest. What could be more cost efficient?

5. My land is windy and we get winter snows. Can I still build a Polytunnel? 

Yes, our Polytunnels are designed with strong steel frames to handle winds and snow, with a little help from you. Site your polytunnel perpendicular to the prevailing winds for good ventilation, and take advantage of a windbreak if you have one. Cross bracing bars can be added to support the hoops in areas of heavy snow. Also, remember that wet snow is heavy, so brush it off to keep the weight from damaging the polythene.

6. What’s the best way to use vertical space in a Polytunnel?

Add cross bracing bars! These horizontal rods were made for hanging baskets, tying up tomatoes, beans and cucumbers. They can also be used to support irrigation and lighting. This is a great way to efficiently use every square inch of your growing space.

7. Does a Polytunnel have a door on each end or just on one?

Feel free to customize your Polytunnel anyway you like, but traditionally a Polytunnel has an easy access door on each end, plus a pair of windows/louvres

8. Is it possible to use my Polytunnel for a chicken coop?

Yes, with poultry netting the hoop design makes a great chicken coop or aviary. Growers have also used shade cloth to create a perfect site for orchids and other specialty plants.

9. What material is used for your Polytunnel frames?

50mm Z35 Tubular galvanized steel is formed into the “hoops” that create the framework of our greenhouses. We’ve found this material to be low maintenance, strong and long-lived.

10. What components are included in a Polytunnel greenhouse kit? 

With every Polytunnel kit ordered we supply a full picking list and detailed instructions on how to erect your structure.

11. I may want to move my Polytunnel; is that possible?

Yes, a fully assembled Polytunnel can be relocated, seasonally or whenever your landscaping plans change. You’ll probably want to call a couple of strong friends over to help, but you won’t need a tractor or other heavy equipment. Try doing that with a glass house!

12. Are Polytunnel greenhouses a good choice for people seeking retirement or second incomes? 

Yes! Our growers have the freedom to manage their own businesses, work part time or fulltime, and to spend lots of time outdoors. Also, many are able to work from home, which is wonderful for families with children.

13. How is my polytunnel delivered?

Our Polytunnels have hoops that can be dismantled, allowing for easy shipping to any home or business address. This approach is quick and economical.

14. Do you have a minimum order?

No, we want to be a convenient source for your greenhouse needs and are happy to take orders, both large and small. 

15. What is your warranty?

We want you to be happy with your polytunne; and we stand behind our product. Our polythene film has a 5 year warranty against manufacturing defects -- most owners get 6-8 years of growing time before slipping on a new “skin”. All other components carry a 1 year warranty against manufacturing defects. 

16. Do you supply gutters?

We supply a profiled steel gutter on our livestock units and our horticultural tunnels. The gutters are manufactured from galavanised steel sheets. Our gutters are thicker than most for a good reason, It allows you to stand in the gutters when resheeting the tunnel. This is makes re sheeting much easier.

17. My ground isn't level, and on a slope, is this okay?

Yes.  We suggest if a steep slope then the polytunnel is assembled at right angles to the slope. Some customers create a number of  beds at different levels inside. We can provide longer ground tubes or hoop extension legs

18. How long does the cover last?

The cover is guaranteed for 5 years against UV degradation. It is expected that the polythene will last 7 years although many people have had polythene which lasts 15 years plus
