I have had 3 of these and they are not great the last one I got was from eBay and it ended up in the neighbours garden the first two lasted a while and they were wilkos walk in greenhouses if you want a permanent structure have a look around for a second hand greenhouse you will save money in the long run I got one off eBay for £75 But if not permanent get a good quality one and not a massive one smaller is better when it comes to the wind.

Thanks Steve, greatful for the info.

You could also make your own cheaper polytunnel with 1" plastic tube from bradfords (underwoods) bent over into 3-6ft canes depending on height/width wanted, and pushed into ground at the edges. Cover these tubes with plastic sheeting weighted down at each end with a long baton (2"x1") stapled to the sheet, which you can then just roll up to the centre for access to each side. A baton along the centre line is useful for this. Elbow grease, staple gun, canes and sheeting is all you need.

Good idea Avkq47 will give that some thought,thank you.

Stuff a cane into the ground at each end of the tubing, to create the bend over your bed, then with a baton runner along the mid-section, with a post at each end, you can 'rest' any rolled up sheeting. I bought horticultural sheet off the internet, but cannot remember who or where, except that it came in 3m widths for as long as you need ... sorry not very helpful, but googling horticultural sheeting should help you. Good luck!
