For those of you with ficus in your chams cage, how do you maintain them? I can't seem to keep them alive in the cage, they always start dropping leaves and getting white spots. I assume either too hot (getting burned from the heat lamp) and probably too much water (from the mistings, water drippers). When I take them out of the cage and just place them in the house by a window, they do great. I read that ficus likes to dry out between waterings and it's easy to over-water them, but how do you avoid that in a cage that is constantly getting water? Any suggestions would be helpful. I really wanted to use live plants in my cham cage but I can't seem to keep anything alive and growing, so right now the poor guy is only getting fake plants.
