I'm no expert either, but we're so close to the sun that I keep the plants out of the sun and in the shade for about a week, increasing the time outside by an hour or two a day. Right now mine are up to 6 hours in the shade, but no nighttime for about a week more. Still way too cold.
Next week I'll time the sun and the exposure so the plants get an hour of morning sun and then increase one hour every day. They should be hardened off in about 2 weeks, though they won't go in the ground until the nighttime temps are 50 or above. Then I hope to cover them with sunscreen as we get hail in June and last year many lost lots of leaves.
Good luck with your endeavors. Whoever said gardening was easy, never gardened.
