Culture
Light:
2400 fc. Light should be diffused or barely dappled. Direct sunlight should be avoided.
Temperatures:
Summer days average 74-76F (24-25C), and nights average 58-62F (15-17C). These average temperatures indicate a probable intolerance to hot summers. The diurnal range of 14-16F (8-9C) fluctuates only 3F (2C) throughout the year and is slightly lower in summer when rainfall is highest.
Humidity:
80-85%.
Water:
Ample moisture is needed in the active growing season. The medium should be moist year-round. The rainfall pattern is wet/wetter.
Fertilizer:
1/2 strength, applied weekly when plants are actively growing.
Rest period:
Winter days average 66-70F (18-21C), and nights average 50-55F (10-13C), with the diurnal range of 14-17F (8-9C). Plants require less frequent watering during the cooler winter, but the habitat is always moist and humidity hight. Fertilizer should be reduced unless active growth is evident.
Growing media:
A fertile terrestrial mix with good drainage. Repotting is best done as plants break dormancy or immediately after flowering.
