If you harden off, thats good. What we do to get a start on plants is plant out if you know you will have a few days of warmth, cover or protect them from cold and winds but I told my daughter her new plants, seedlings and cuttings would be fine down to 38* with no covering. (In Feb) and everything pulled thru with flying colors and never hiccuped. (Except the sunflowers, darn snails) Good luck!
