• Although it is very rigid now, when assembling the greenhouse it was quite fiddly and you need to follow the instructions very carefully as some of the bolts have to go in early in the build for fastening later. All that aside it is good value for money. I have fixed mine with some small metal brackets and it is very solid. The door is a bit hit and miss to open and shut but not really a problem once you get the hang of it. On reflection I would buy this again

Polycarbonate Greenhouse Questions

When purchasing a polycarbonate greenhouse there is always questions everybody asks. We hope we answer a few of those questions.

Are Polycarbonate Greenhouses any good?

Polycarbonate greenhouse is great to have they are a lot cheaper to maintain and replace any panels if you lose them. They are safer because if the glass smashes in a glass greenhouse it can be sharp, cause an injury and a mess.

Polycarbonate greenhouse is good for keeping warm in the winter with there UV panels they will only let natural light in. There will be no need to paint the panels as you do with a glass greenhouse. Glass greenhouses can scorch the plants from the hot sun rays.

How thick should the polycarbonate sheets be?

When looking for a greenhouse ideally you want to be getting one that has polycarbonate sheets that are around 4mm – 6mm thick any less and they won’t last as long or keep the heat in as good. Don’t always go for the cheaper option when buying a greenhouse. Spending wisely could make it last a long time.

Polycarbonate Greenhouse Tips

Once you have bought your polycarbonate greenhouse there are some tips and advice you need to know to maintaining them and growing in them. Hope these greenhouse tips help.

How to secure your Polycarbonate Greenhouse

When you are building your polycarbonate greenhouse you need to spend extra time securing it. The reason for this is because you see so many posts online about the bad winds blowing them over and crumpling them. Make sure you have secured it to the ground as much as possible either using a greenhouse base, concrete or paving slabs and screwing it down.

For the panels make sure you use as many greenhouse clips as possible. Once you have done this go-round each panel with silicone and seal it. This will stop the plastic windows blowing out. If one does blow out fix it straight away because if the wind gets in the greenhouse it could blow more out.

How to clean and maintain your Polycarbonate Greenhouse

To grow successfully in a greenhouse you have to spend time maintaining and cleaning them. This can be a yearly thing, usually in the winter months once your tomatoes and cucumbers have died off.

To clean your greenhouse you need to wash and disinfect all the windows and framework so that they are gleaming. Make sure there is no moss or mould anywhere. Cleaning and disinfecting it will kill off any diseases which may be lurking in the greenhouse – leaving it could cause tomatoes, cucumbers and plants to catch something bad. Ideally, you want steel or aluminium staging and shelves as this can be cleaned easily for the year ahead.

Each year go round and make sure all the panels are firmly in place, any old greenhouse clips replaced and sealant fixed around the windows. If the greenhouse is glass replace any cracked windows.

Make sure all the greenhouse guttering is clear of leaves and that it’s connected up to your water butts ready to catch the winter rain for the next year. Why not set up multiple water butts to catch as much rainwater as possible.

Growing in a Polycarbonate Greenhouse

When you purchase a polycarbonate greenhouse it’s always exciting to learn to grow and knowing what you can grow in it can always be confusing. In a greenhouse you can start all your flower and vegetable seeds off at the beginning of the year depending on the temperature, if you have a greenhouse heater that is always a bonus, this is where a greenhouse thermometer comes in handy to keep an eye on the temperature in the day and the night.

Greenhouses are obviously popular for growing tomatoes, cucumbers, peppers and chillies but you should try growing melons also as they are delicious and you can have some great success from them. If you have not got room for a greenhouse you could always opt for a grow light for indoors.

Polycarbonate Greenhouse Conclusion

Our overall conclusion of the polycarbonate greenhouse is that it can be worth it’s weight in gold. We would rather have a plastic one than a glass greenhouse which can be dangerous. As long as you follow our tips for securing it well it should last you years of enjoyment.
