Orchids require bright light to bloom such as an east, west or south window but they should be protected from direct sun. Too much light will burn the foliage and too little light will result in little growth or no blooms. Lady slipper orchids and moth orchids can be grown under fluorescent lights also. Generally blooms will occur when the night temperatures are 10 to 20 degrees colder than the day temperatures . Orchids require a high humidity of between 40 to 85 percent by using humidifiers or by filling a tray with pebbles, saturating the pebbles with water and placing the pot on the pebbles.
Orchids appreciate good air circulation from small portable fans or ceiling fans.
The potting mix should provide good air penetration and fast water drainage . Commercially prepared orchid mixes are available. Most mixes are a combination of shredded fir bark, peat moss, perlite or sand. Orchids which naturally grow in trees can be grown on slabs of wood. Orchids should never be dug from the wild.
