"Light. Various sarcochilus species and hybrids have differing light requirements and this must be taken into account for successful culture. In my shade house there are four zones with significantly different light levels.
Zone 1 - Plants at bench height near the eastern wall, where they receive bright light, particularly during the morning. This zone is most suitable for Sarcochilus ceciliae and many of its hybrids.
Zone 2 - Plants at bench height in the middle of the shade house, well protected from the western sun in the afternoon. This zone provides dappled light and is suitable for S. hartmannii and many of its hybrids.
Zone 3 - Plants hung below benches facing north, well protected from strong sunlight throughout the day. This zone provides plants with high humidity and low light levels and is suitable for S. falcatus, S. fitzgeraldii, S. olivaceous, S. serrulatus, S. spathulatus, S. weinthalii, Plectorrhiza tridentata, Rhinerrhiza divitiflora and selected hybrids.
Zone 4 - Plants hung below benches facing south. Plants receive only indirect light. This zone provides high humidity and lowest light levels. Sarcochilushillii, young sarcochilus seedlings and plants showing stress are grown here.
S. dilatatus and S. hirticalcar are grown in a heated glasshouse maintained at temperatures above 9°C and at light levels approximating those of Zone 1.
Sarcochilus species are placed in the various zones on the basis of conditions in their natural environment, although some trial and error has been necessary to determine optimal conditions of growth and flowering for some. As might be expected, hybrids are more tolerant of their growing conditions and may do equally well in two zones. In some cases, however, one parent may dominate and thus influence the choice of the most suitable zone. For example, hybrids bred from Rhinerrhiza divitiflora grow much better in the lower light levels of zone 3 than they do in zones 1 or 2. A certain amount of trial and error is needed to determine the best zone for some hybrids."
