Don't be tricked into thinking you can buy a pack of orchid seeds and sprout them like other houseplants. The seeds of orchids are extremely tiny: ranging in size from nearly invisible dust-like particles up to the size of the smallest seed of some herbs. In the wild, these seeds rely on a symbiotic relationship with species of fungus in order to grow. To grow them yourself, you will need access to laboratory equipment such as an autoclave and laminar flow hood, as well as knowledge of good aseptic (sterile) technique. The seeds are grown in flasks on an agar based medium. These seeds are usually acquired as seed pods or by weight. Ask many questions of anyone claiming to sell 5 or even 50 orchid seeds. The seeds of most species are far too small to count-out in this manner.
