Morning glories do NOT like cold temperatures! 35 is too cold for them. What you could do, if you have them, is put your starts into either somewhat larger peat pots or metal coffee cans with the bottoms taken off and replaced with the plastic lid (suitably perforated for drainage). That way, you can either plant the whole peat pot or take the bottom off the coffee can and plant the whole can when you're ready to put them out. I've done the bit with the coffee cans and it works very well for any number of plants.
