How hot can hot weather crops tolerate?

A follow up to my okra experiment: I have okra seedlings growing in polytunnels and they are just forming their 1st true leaves. With the strengthening sun and long days, I am observing 1" soil temps of 110-115 degrees F. The okra looks quite happy so far. I haven't ventilated the polyhouse in the hope that it will give the okra a competitive edge over our temperate weeds. Do you think it's too big a risk? I would love to let nature do the weeding.
