I have had my newly rooted cuttings in my covered screen porch for a week now. I waited until the night temps stayed in the 50s. It is my plan to keep them there for at least another week until they are hardened. In this environment they can toughen up a bit with breezes and get diffused sun a part of the day. Even in this protected space the leaves will droop a bit when they receive the partial sun. After the first week this stops. I will move them to the sun porch after that for full exposure.

In your case, definitively stick to the shade for this first period. If you do not do this, the indoor leaves will dry up and burn with direct sunlight as quick as the first day.
