It's still going to get cold at night, probably too cold for those southern crops to start well because they want a steady temperature. You can help by putting mass inside to warm up in the daytime. Bricks, a wall of your house, patio stones, rocks, bottles of water etc . Consider a a blanket at night. Maybe a small heater, old waterbed heaters work pretty good and have a thermostat, even an incandescentlight bulb will make a fair amount of heat..
It's going to get hot in the sunshine too, and quickly so you'll need to be around to open it up a bit to regulate the temperature.
