    Polycarb and the like is widely regarded as being prone to blowing away in strong winds, coupled with the fact that its lightness means manufacturers can reduce the strength of the frame (and the price of course).

    Make sure you anchor it down well, and you may have to put the panels in with Silicon to stop them blowing out (which will then make it a pig to disassemble - if ever you have to)

      I can't see any windows included for that price, nor a rectangular base/plinth for it to sit on, nor integral guttering, which could well make this greenhouse comparatively more expensive than lots of others, especially taking account of regular 15-20% off promotions from the likes of B&Q, Homebase, etc.

      Especially perhaps, in the absence of any windows, the only method of ventilation is having the door open?

      sorry for late reply. i bought a base myself reading that where she got the greenhouse from didnt supply 1 and another customer commented on the fact it didnt come with 1, i was always thinking of bolting it down so that wont be a issue , the glass i may just put a very small , and i mean small blob of silicone in each corner just to hold the glass in , but i would wait to see how the wind effects it 1st.

      but as a whole your views , will it do ?, or should i be polite and tell the misses to send it back?.

      No personal experience, but from memory I think folk here who have reported of panes being blown out have managed to solve the problem by silicon'ing them in. But I wonder if you need to properly silicon them in, rather than just the corners?

      Nice to have a greenhouse though :)

      Plan B might be to procure a second hand one - eBay or Freecycle or similar - if you are OK at DIY to disassemble it, cart it home and then re-erect it. You get a lot for your money, compared to a new one, and the old ones on offer tend to be strong ones 'coz they are still there! It wno't look Shiney New though ...

      If you really want an honest opinion, I think there is nothing wrong with it but it may be too small. The picture looks rather deceptive to me. According to the dimensions in the advert it is 6ft x 4ft (I think my rough calculations are correct). Definitely doesn't give that impression in the picture!

      I've just looked at one of their other, larger, greenhouses and they use the same picture. It's highly unlikely that your greenhouse will look like the picture because panels are normally at least 2ft wide. I'm trying to imagine what 'double sliding doors' will look like in a 4ft width :scratch: and if they put them in the 6ft side you will have lost a lot of working space.

      Most people find that, after one season, the greenhouse they buy is much too small. If you only have space for that size, then it's OK.

      According to their returns policy, you can only return it if you don't assemble it. So you will need to make up your mind before doing anything to it.

        You will definitely need some opening vents in the side and the roof, does it come with any?

        That's what concerned me and I think it's a major omission.

        The pic doesn't show any windows:

        Do you mean glass or Polycarb panes, Mr N?? Glass should be secure with clips and maybe some silicone on the clips to anchor them even more. Polycarb bends in the centre under wind pressure and that blows the panel out if the pressure is big enough. Silicone does help to anchor the panels but, to be honest, not greatly as when the panel bends inwards, or outwards, under the wind pressure that will drag the panel out of the seating just like a sail.:dunno::snork:

        Shiney's right, nearly every garden with a Green House wants a bigger one!:heehee:

        My first, when I was 15, was 10' x 8'. At the time I wanted the 12' x 10' but didn't have enough pocket money saved up ...

        First thing I got when I bought this house was a 12' x 10' that I had wanted since I was 15 :)

        And then I bought a 30' x 10' ...

        ... I won't tell you how big the one I'm considering now is ...

          well it came and is now erected and to be honest with it am very pleased, the doors are a little tricky but that maybe my fault , the only 1 gripe i have is i listened to 1 of the reviews and bought a base from a certain supplier only problem is the greenhouse is 8 inch shorter then the base, but not to worry i can soon sort it , the problem with the glass blowing out i cant see happening on this 1 anyway they seem very solid indeed , i just thought i would pass this on incase anyone else was thinikning of getting 1. :)

            I have a couple of these (plus a glass one) and I am happy with them - never had a pane blow out - the only thing I should have done is seal the complete edge of the roof sheets as over the years water has got into some of the tubes (it looks like 2 sheets with tubes inside) and it just looks messy - but still works. On hot days with the door shut it gets very hot (steams up my glasses) but once the door is open this improves - I also hose in there to cool it down sometimes.

            I think it is warmer in winter than the glass one - perfect for my overwintering fuchsias although condensation is a problem in the Autumn - but there again I don't have full sun on mine all year as once the trees leaf up morning sun is lost and I mop the roof if it gets too bad.

            Enjoy :)

              I bought a similar greenhouse, ex display, from B&Q a couple of years ago.
              Now I realise it could do with a roof vent. Does anyone know whether I can purchase and fit one now? I can't find anything on-line except thermostatic openers.

              i have come to the same conclusion david , its too hard to regulate the heat , i thought about cutting a window into the roof somehow and buying 1 of the automatic vents what copen and shut with temprature changes but didnt fancy screwing the whole thing up

              There should be a local Greenhouse Dealer in your area who should be able to supply you with roof vents, one vent is fine, two is better!!:snork:
