The cost of 2000 Euro is ridiculous unless you are looking for something hugh. 2 years ago I bought a 6ftx6ft aluminium GH with glass windows and sliding door - it is fabulous and I grow all my autumn rooted cutting, my Cosmos for planting out (this year, I hope in, in late May) plus bedding plants which we buy in early May and grow on. My seedling Toms which now are 6 inches high and will be grown in the GH (heated until mid to late May to 50-60 degrees) through the summer and autumn. Look at Halls Greenhouses or similar for quotes. I am sure I did not pay more than £350.00 complete. |

I was actually pricing a 10'x6' the cost 2,247.00 Euros. Crazy price! One of the reasons I didn't go for glass was the mention that glass can scorch seedlings. I really want to grow summer bedding for family and friends and of course the fact that I love it immensely. This side of gardening is new to me. Are you talking about twinwall polycarbonate or clear sheet? Anything using clear sheets will potentially scorch seedlings on a strong sunshine day even if you have thermostatic vents. Twinwall is different in that it diffuses the light - reckoned not to be so good for growing tomatoes but it didn't seem to bother mine. Bubble wrap is OK as a diffuser to protect seedlings and keep heat in. Polycarbonate is a bit inclined to flex and spring out which might not be ideal in a windy location unless they are properly captive. My experience with wind loading in a very exposed spot and a 20x10 green house suggests that no matter what you buy to resist the worst storms you actually have to use stronger diagonal cross bracing on the side that faces into the prevailing wind if it is aluminium frame. The wind was gusting to 100mph and crumpled the aluminium struts which then broke the glass. Once wind was inside the structure it rained sheets of glass down in a neighbouring field. It wasn't safe to approach. This was what happened to mine in the winter of 1997. You could also consider a wooden and twinwall polycarbonate construction by a local handyman. If you intend to heat it then the fuel savings of a twinwall insulated greenhouse are significant. Not as pretty as glass or clear. -- Regards, Martin Brown |

Thank you for replying. I have now found a company called 'Steeltechsheds' they say their greenhouses are built to last a lifetime and are able to withstand extreme weather conditions. The frame is made of Steel Hollow section. If you could take a look at their website and tell me what you think. |

Hello Martin. Thank you for replying. I have now found a company called 'Steeltechsheds' they say their greenhouses are built to last a lifetime and are able to withstand extreme weather conditions. The frame is made of Steel Hollow section. If you could take a look at their website and tell me what you think. Having looked at that site, I wouldn't touch them. The frame may last a life time what ever that means. The plastic sheeting may last up to around 10 years but 7 would be more realistic.It may well discolour with sunlight, and tends to get brittle. David Abacus Nurseries. I can see no ventilation, and you should ideally have 1/8th of the roof area as vents |

I don't see those poorly supported polycarbonate panels standing up to coastal weather , either. Why buy steel (which rusts) when all the other manufacturers use aluminium, which doesn't. No explanation of the "lifetime" guarantee, either.. how long has the company been making GH's? Janet |

David Abacus Nurseries. I agree. I am sure some local woodworker/shed maker could make a proper wooden frame to take standard size twinwall polycarbonate with proper uv inhibitor in. It will degrade in time but is worth it if you intend to have a heated greenhouse. Otherwise I would be very sceptical of a mounting system that does not support the sheets in the middle as well as at the edges. Plastic unlike glass will flex considerably in the wind and so a plastic greenhouse needs a stronger frame. I can see no ventilation, and you should ideally have 1/8th of the roof area as vents I agree. I don't see those poorly supported polycarbonate panels standing up to coastal weather , either. Ventilation seems to be an optional extra - which is a nonsense. Seems like these are greenhouses specifically designed for non-gardeners. Why buy steel (which rusts) when all the other manufacturers use aluminium, which doesn't. You could at least in pricinple have a much stronger large steel structure for the same price as aluminium. And steel is less likely to cripple under extreme wind loading. I would recommend replacing some of the struts on the prevailing wind side with thicker material. My failure was in the winter of 1997 http://www.nezumi.demon.co.uk/garden/gizmos/gizmos.htm I expected a few panels to fail most winters from flying debris. We have some pretty strong winter storms in North Yorkshire. No explanation of the "lifetime" guarantee, either.. how long has the company been making GH's? Janet Not long judging by the lack of ventilation on roof or sides. Regards, Martin Brown |
