The miniature species and hybrids are somewhat less demanding with regard to temperature and are the best candidates for indoor culture. A well-drained potting mixture is required for best results. Cattleya species and hybrids are the most common commercial orchids. These orchids are epiphytic and require intermediate temperatures and high light intensity. The species often have a stringent rest requirement between flowering cycles.
Many hybrids are much less demanding and make good indoor plants.
Dendrobium species, especially Dendrobium phalaenopsis, are good candidates for indoor culture if large size is not a problem. D. phalaenopsis is an epiphyte requiring intermediate temperature and relatively high light intensity. Watering should be reduced during this period but not stopped. Some varieties may flower without a rest period. They grow well under relatively low light intensities and are good plants to grow under fluorescent lights.
