Most species and hybrids are compact enough so that they can be easily accommodated on windowsills or under lights. Masdevallias can be kept in light intensities up to 2,500 foot-candles if the growing area can be kept cool. Plants grow well under standard fluorescent fixtures and can be summered outside in shade. In the home, place in an east or shaded south window or under artificial lights. The plants will grow slowly and eventually expire if temperatures remain high for long periods.
Cool evenings help reduce heat stress during the day.
Good-quality water low in dissolved solids is imperative for success. The ideal range is 60 to 80 percent. In the home, set the plants on trays of gravel partially filled with water. In the greenhouse or enclosed growing area, humidity can be increased by use of a humidifier, while evaporative coolers help raise humidity and lower temperatures. If plants are summered outdoors, automatic misters under the benches are recommended as is more frequent soaking.
