"..However, speaking of Sarajevo resistance varieties to frost, you should know that this is only possible at low humidity (dry air) and windless weather. For a long time scientists advised growers evening and night watering as effective against frost but this is false. Wet surface gives four times more heat than dry.”

I saw this for myself this year... tomatoes in dry soil sailed through the frosty nights with no damage. When I watered them in the afternoon before a cold night, the leaves were a mess by morning.
