Murashige and Skoog media preparation

[cfreidsma]

I got this today, and it didn't arrive with instructions. I am assuming that I follow the instructions for agar, and add this to the agar before it cools. I just want to make sure that I don't need anything else.

HiMedia PT022-1L Murashige and Skoog Shoot Multiplication Medium A with CaCl2, Vitamins, Sucrose, IAA, Adenine Sulphate and 2iP, 1 L: Amazon.com: Industrial & Scientific

I am planning on doing tissue culture of assorted plants, orchids included possibly.

Edit:
I am going to add sucrose, benzylaminopurine, naphthalene acetic acid, and the agar.
