Thanks a bunch Mayres and Biscuit! I live in Kansas so I have to keep it indoor. It's in moss on pebble tray, facing an east window with long hours of indirect sunlight. I didn't know it's such a cool grower. But boy if it likes 45oF nights, I'll have to keep it in the fridge - just kidding. Maybe I'll do what I read somewhere, put it on a bed of ice to simulate cold nights. I welcome the fact that it doesn't like to be repotted very often because it's too scary to work with delicate thin roots. Thanks and I'll see if it likes it this way
