Wait until there is no wind before you try to put the poly in place.

And anchor it down well.

I have had my tunnel for 2yrs now 6mx4m, when erecting ensure that the frame is square by measuring corner to corner, must be equal. When you put the cover on any left over material is buried a spade depth all around the perimeter, on each corner i have put a half tanalised field post ( the type farmers use for field bounderies) buried 2ft deep with one bag of post crete round each post, then screw from the inside through the corner frame into the post. I have had some gale force winds in the past and nothing has bothered it.
Good luck with it.
PS I grew sweet corn, chillies, red peppers and cucumbers in mine this year!

This is an interesting Topic and also quite argumentative although I have no views either way ! I do have PT which is down to the ground and has done me well . However the current advice I am getting from the pro's is to leave a 200mm air gap around the base ! I have not tried this or tested it :)

I wonder where the Pro's are getting advice from? ref. airgap, mine has built in ventilation panels along each side, if i raised it 200mm all around the wind would get inside and destroy it, i have an exposed site.
I have seen the sides raised by about 1m, this would allow the wind to blow through and not try to lift it like a ballon, but using them for a living i suppose the Pro's have got to get it right.

Horses for courses - I think it would depend on what you are going to grow in it.
For example, the ones they were using to cover fruit trees, in the harvest programme last week, had completely open sides ;)
I wouldn't want to let that many cold draughts into one I was using to grow seeds, or for early plantings, in the Spring. Just need to make sure there is enough ventilation to stop things going mouldy,

I tend to agree mum but the idea is you have less wind damage and losse's
