Types of media for stem propagation

[AAWilliams]

Hi,

I am a student in urban horticulture at ASU Poly in Phoenix. In order to graduate I need to do a research project.

I would like to do stem propagation of Phalaenopsis orchids using different types of media to determine what works best and why.

The orchid source has media specifically for stem propagation of Phalaenopsis orchids. I would use that as a the control. The second test would be using the same media with keiki paste (?) and the third would use something else that is unknown at this time (any suggestions would be appreciated).

Does this sound like a reasonable experiment, are there other types of media or propagation methods that would work better? Not having done this before I am open to any and all suggestions. The only caveat is that the experiment can only last sixteen weeks (the length of a semester) as I hope to graduate when this is over.

Thanks in advance for everyones guidance
