O753 multiplication medium: this medium is used for establishing stem props of phalaenopsis and dendrobiums. This is pretty typical stuff, but with 2.0 mg/L of BA. It is used for making stem props- it is NOT for germination, replate, or other weird things you may wish to use it for, but probably shouldn't.

This medium is based on Murashige and Skoog salt base with 20 grams of sugar and all the other goodies (inositol, peptone, B vitamins- the whole kitchen sink is in there). Inexpensive and reliable. Contains gelling agent (agar). Add water to 1 liter final volume, mix thoroughly, pour, and autoclave.

Please note: Making stem props from orchids is a technical matter. If you are not familiar with the process, I recommend looking up some videos on YouTube, and doing some web searches for more information before buying media.
