How to grow Orchid from seeds: Phalaenopsis orchids, perennial epiphytic plants that grow on trees in their native Asian environments, are typically cultivated in homes or greenhouses where indirect sunlight conditions can be reproduced. Also called moth orchids, as their flowers give the impression of colorful flying moths, these members of the Orchidaceae family prefer temperatures of 75 to 85 degrees Fahrenheit during the day and 60 degrees Fahrenheit at night, though they also survive outdoors in USDA cold hardiness zones 6 through 11. Growing phalaenopsis from seed, though possible, is difficult, as the process requires strict sterilization procedures to prevent contamination.
Pour equal amounts of distilled water and agar-based orchid gelling medium into a cooking pot and boil the mixture. Flask the mixture, filling the glass bottles to one-fifth full. Rest the lids on top of the containers without twisting and cover the tops with aluminum foil. This creates a contained environment without risking the lids sealing permanently. Bake the bottles, along with another empty bottle, for half an hour at 250 degrees Fahrenheit to sterilize the medium. When the bottles cool, remove the foil and twist the lids closed. Place the bottles in a safe spot for three days, which is long enough for bacterial contamination to appear, if it exists. Dispose of any contaminated bottles. Boil water in a pot covered with a small grill section, so that steam rises onto the grill section for sterilization purposes. Put on a pair of rubber gloves. Wipe the grill surface and the forceps with a paper towel soaked in 70 percent ethyl alcohol. Lay another paper towel soaked in the alcohol on top of the grill section.
