Greenhouse or Poly tunnel

Time to replace the shed. I think I will go for something to plant in.

I am on the coast, it's very wild and things like PIR light fittings that I fitted by the hundred inland are only good for a couple of years.

So what is best, I see a few poytunnels around, not many, but have only seen a greenhouse in Woodies, Tralee. They do not seem popular.

As my normal practice is to eventually buy the thing I should have bought in the first place, has anyone an opinion?

I live within 500 metres of the sea.

Wow! It must be nice to live so close to the sea. At least in some ways.

Yes, everything corrodes though.

I used to run Ford Focus's into the ground and never replaced a brake disk until I spent a couple of years here.

Even dropping an aerial lead down the roof, which is common practice inland, resulted in the outer insulation and braid wearing through in months.

I don't have the experience, so I'm hoping someone else has done the groundwork before I jump in and buy.

Corrosion and the chance of the thing becoming airborne seem like distinct possibilities.

I have my doubts that warranties would extend to the gales we get here somehow.

We had a greenhouse that was blown flat in windy weather. We have had three polytunnels, the latest one was supplied and fitted by polytunnels direct. We are only on the third as we have moved twice, they all stayed up in high winds.

I highly recommend these guys.

Many thanks,
I am looking at a polytunnel. Thanks for the link, but I found someone local who is coming around later today.

It's funny, but what started out as a casual enquiry as to growing tomatoes more successfully than last years attempts gave an introduction to a whole new area.

Greenhouses were astronomical in cost for this area and even should I want to part with a few thousand for one, they seem to be on a very long delivery time.

Thanks for the information, the polytunnel it seems to be. I thought if I went local the supplier knows the conditions well and it keeps the money in the area. They are a nice crowd around here :-)

On a final note, if it wasn't for the partial success, I probably wouldn't have bothered trying to grow things like tomatoes and chillies. From what they told me at the garden center this week though, it seems that I picked the one exceptional year and normally I could expect a few green "berries" at best.

Polytunnels are amazing, you get much more space for your money than a greenhouse and you don't have to just garden in there, we always have a couple of chairs and a radio, nice to have somewhere outdoors on wet days to putter about.

Thanks, it crossed my mind that it might be good to sit in there, relax and admire the lawnmower and all the rest of the garden tools at my leisure :-)

I started work on a concrete foundation and walls last year for a sturdy concrete/ metal frame/ 8mm Perspex greenhouse as we have strong storms out here but I'm starting to think I should have just bought a polytunnel as Perspex is expensive section to buy and I'm still saving for it :/

I got my polytunnel 7 years ago from here
His name is john.
It's taken every thing the west has thrown at it and still going strong.They were a bit cheaper back then. But still I don't think you will get a better tunnel for the money. The frame is so strong and the plastic is tough. Back when I bought it for the price it was, there was nothing better out there.
I do believe you wont go wrong getting one from john. my impression of him back then nice and very honest.
Just dig your trenches a little deeper for your frame and bury plastic well considering your location. This applies to what ever you put up.
Try to pick sunniest and most sheltered location you can as well for what ever your going to to get.

I did some research though and few locals have them. I was to have someone come tomorrow, but after phoning a few suppliers, they thought the area was too wild to give a firm warranty.

I have gone for an Optima greenhouse which is like a polytunnel. It uses 6mm polycarbonate and will be installed in a month's time'

The warranty extends to an orange gale warning, so I am counting on being able to install a windbreak around it, with removable framed breaks so the light will be unobstructed in summer.

The unit is made of readily obtainable components, so in a worst case scenario, I will collect the bits from the surrounding fields and rebuild in the very sheltered back garden.
It will be a bit dark for plants, but it will be a useful shed and will keep the ducks dry when it rains :-)

Hi kwackers,
I found an optima 8x2.5m greenhouse (which is about 24x10ft) but it uses 4mm polycarbonate.

I can't seem to post link but it was from a website called Weisa .lv/ en/ products/ greenhouses.

It's seems to be Ä495.
It this the right one you have?
Where did you find the one with 6mm polycarbonate?
Did you have to purchase it outside Ireland?

Did you bolt it down to a concrete foundation?

I found a clear solid 6mm polycarbonate sheet 2440mm x 1220mm for Ä149.90 (excluding vat) on 365 plastics website.

I noticed the multi wall sheets being used, for example on Tesco's external trolley bays, and the multi wall got dull with green algae and dirt within a year so I'm hoping the solid sheets of acrylic or polycarbonate stay transparent longer.

What are people's experiences?
Are sheet prices cheaper with a different website / company?

Sorry, I did a PM accidentally,
as there are one or two contributers, I will repost:

have the Optima on order. It's 3 meters by eight
I ordered it with an 8X1 meter raised bed and the lot installed is 1785 euro

The company is KSB and it was the one recommended to me originally, before I did all the research, the recommendation was by a customer at the garden center.

The center is Shanaghans Tralee/ Farranfore incidentally, [a bit of a plug but I find them great, they help duffers like me and have lots of patience].

I think KSB are in Meath, and they seem pretty helpful also. The manager says if I order my own shelving locally he will install that too.

He also said that they have them installed on the Arran Islands without protection when I asked about windbreak recommendations, so I'm hopeful that it will last a year or two.

Oddly enough I ordered some of the windbreak timber today anyway. Eighteen 3X4 and ten 1X2 inch by 4.8 meter lengths of wood that I'm adding a few bags of cement to in the hope everything remains in Kerry :-)

Thanks kwackers,
Hopefully it will last longer than a year or two and stay on Kerry soil :)
