All looking good to date

I bought this greenhouse to provide hens with a covered outdoor space when weather poor.
All parts were supplied correctly and fitted well. Good value although I realise that is not highest spec steel tube for this price. Only had it for a week but very happy. Probably will fix to timbers for more sturdiness and portability.
