Don't do one like in the picture, it won't hold upto the snow. You need a gothic arch (although some take the plastic off each year, I don't have experience with that). If you bend your gothic arch it will be just a little more work but well worth it, this is an example of the kind of arch I mean https://www.farmersfriend.com/p/gothic-caterpillar-tunnel

I would not trust pvc pipes, I would personally look at trying to source some chainlink fence posts and use a pipe bender on them, you can set in your limits on a board so that all your bends are repeatable.

Worth looking into the NRCS who do a season extension grant for poly tunnels, go talk to your local extension and you may be able to get one for free but they have rules that you will need to be up on.

Personally when I build my next one I will probably use wood and frame it out, then use polycarbonate instead of plastic film and would be more interested in a Chinese/arctic style greenhouse (southern side exposure with northern side covered up and used for a thermal mass etc).

Was a few years back but I used to buy it at https://www.facebook.com/people/Liberal-Beef-Co/100023842616162/ to make pemmican.

Lads, I don't know how to stress this more thoroughly but I saw some very suspicious crows this morning. They were behaving more like seagulls than crows which is very worrying, all I am trying to say is hide yo wife... hide yo kids.

When you get up here you here you will probably realize that you don't desire to goto MA/CT or those kind of states..
