Help me protect my broccoli

I need some suggestions for fall frost protection for my beds. I've got broccoli and peas (direct seeded 6 weeks ago), and cabbage and carrots (direct seeded 3 weeks ago). All the plants are still pretty small (broccoli 8", peas ~12", cabbage and carrots minute).
I'd like to get them all to harvest. How far will I have to take these into the fall?
I've heard about row covers, except these are beds (around 5' x 3') and the plants are not in rows.
Any suggestions would be much appreciated, Greg USDA Zone 5, Toronto

make a hoophouse over the beds. You need, I think, 1" PVC (I have my own tunnels, but right now I can't remember the diameter of the pipes), 2 to 6 mils poly, and something to hold it down. Territorial has clamps to attach the film to the hoops, and they specify the diameter. Use the biggest ones.
