Yeah I have two terrors-3 and 5. The girl loves the figs like me and the boy has taste buds like his Mom. LOL
The old timers do it this way. After a year if they come back you know. It's rare that they don't.
My dad did it this way with no problems. No worries about humidity or light.
I did the moss, bags and paper towels in bins with moderate to good success. But the hassle is too great. They did well under grow lights in my basement. But then again your in paradise and I need the light to carry them over for the winter.
IMO people worry too much about whether roots are forming. Like Ron Popeil, Set and forget it! ( As long as water is added). ;-) Obviously they are the most important thing but I would fret over them to the point of not enjoying it.
