Different types of orchids can be found growing everywhere from deep shade to full sun. The most commonly available orchids we grow at home need bright indirect light at a minimum, and in some case direct sunlight. We photographed this Brassvola orchid is growing in dappled sunlight along a riverbank in Belize.
Add less sand to your potting mix than for other species. Haworthias and some other succulents also prefer bright indirect light to direct sun. LIGHT: Indoors, give cacti and other succulents the brightest or sunniest window you can provide (four to six hours of direct sun). In less light, they will become long and skinny, an abnormal growth habit.
