How did you wet it when you began the blocking process? If you submerged the item and then spun or towel dried it, it should have been sufficiently damp to block properly unless it took you a long time to get it situated to start drying.
If you blocked it out with the blocking wires and then spayed it until good and damp I'd think it would be okay the way it is. Just make sure you don't jump the gun and take it up before it is 100% dry. In New Mexico and with lace weight yarn I wouldn't think that it would take too long to dry properly. If it was properly wet the first time, doing it twice won't add anything.
