My fiddle leaf fig finally stopped dropping leaves after I moved it away from the heating vent

My fiddle leaf fig finally stopped dropping leaves after I moved it away from the heating vent. I spent months thinking it needed more water or light, but it was just the dry air. Now I keep a humidity tray underneath and mist it every few days, especially in winter. It's putting out new growth for the first time in over a year, so I'm pretty happy about that.
