Correct me if I'm wrong mark, but I think you want to exchange all the air one time per hour, even at night. This would be for early in your season when the sides are down and you are running your heater. This is why you need the end vents at a minimum. It would be overkill doing the auto sides for this and would be too much wear. They would be good for summer with the gable vents like cole mentioned.
I agree with the insect netting. I will be outfitting both of my tunnels with it this year. Look specifically for greenhouse insect mesh that excludes thrips to get the micron size small enough to keep them out along with whiteflies.
