He claims as long as you wash the frost off before sunlight and keep it washed off, frost will not damage the plants. Works for him
I only grow a couple hundred or so plants, but constant overhead irrigation in the wee hours - usually 3 to 5am or so until early morning (it usually gets the very coldest just before dawn) has worked very well for me in the past.

However, for the last three years - I now wrap my cages as soon as I plant out in mid-weight row cover that protects down to 28F and leave it in place until all possible chance or frost or freeze has passed. Takes a few hours to apply, but does save me a lot of worry later.
