I like to keep them inside until good and rooted, mainly due to wind and rain. I even keep my up potted (1 gal) inside for a few weeks to control the watering, under grow light and in a window.
I transition to sun very slowly and I still end up burning leaves. My deck has perfect transition, one side gets no direct sun and it transitions to full sun all day on the other. I step them out, 1 week full shade, then 2 hrs AM sun 1 week, then 4 hrs, etc. I find if it rains and the sun comes out the droplets on the leaves act like a lens and burn tiny circles! This is when they are in transition.
