LFS in air-con room where it is cool, then it is fine. But like I told Tarence, if the temperature remains 28C and above then start worrying. The roots rot very quickly and once that happens, nothing you do can save the plant.

So keep the humidity as high as you can but with good ventilation. Amongst other taller plants in a windy area helps. And allow the top of the LFS to dry out a little before watering and no water tray.
