Light:
1200-1800 fc. Diffused light is preferred.
Temperatures:
Summer days average 70-75F (21-24C), and nights average 56-63F (13-17C), with a diurnal range of 11-14F (6-8C).
Humidity:
80% throughout the year.
Water:
Ample moisture is needed in periods of active growth. The rainfall pattern is wet/drier, but humidity levels in the habitat indicate that fog and dew provide some moisture in the dry period.
Fertilizer:
1/2 strength, applied weekly when plants are actively growing.
Rest period:
Winter days average 65-70F (18-21C), and for 5 months nights average 52-56F (11-13C). Highs and lows decline simultaneously, maintaining a uniform diurnal range. The rainfall pattern indicates that water should be reduced in winter with a 1-2 month dry period occurring in early spring. Fertilizer may be reduced or eliminated, and light increased for 2-3 months.
Growing media:
A fertile terrestrial mix with high humus and good drainage.
