I have a dozen or so ficus 4 of which I have in a 50 gallon aquarium outside under my bench. Its under my bench only because I had a problem with my puppy getting the plexiglas lid off it. Though it is under my bench it still gets about 6+ hours of direct sun. From noon till sundown. Last week the termometer outside my kitchen window (part of my bench runs under it) probably averaged 98. I could only guess in the aquarium was well over 100 and I have had fast and more growth on the 4 in the aquarium then the ficus on my bench. They LOVE heat and humidity! Oh and I have schefflera cuttings in the aquarium also and they put out a spread of roots the size of my hand in 2 weeks
Another thing, the ficus on my bench have been putting out more growth during our heat wave then before. Mixed with the east coasts high humidity it's sure proof they love it.
