Depends upon how many staghorns you really want to grow, Heath. I guess I just don't see the point of starting from spores on these. First you have to nurture them to germinate, and grow tiny plants - do you have a greenhouse? Then you'd have to pot or mount them all which involves a lot of time, effort and expense.
I think you'd get better value, for sure buying a plant already started. Here's Ken's site, where you can get a nice small plant for $12.95 plus shipping.
