Lindsey,
As you had so many test positive for viruses, are you convinced they are positive? I know that many orchids never show symptoms but... Maybe a re-test of those plants in a couple months?
On another note, having plants that do test positive is not a death sentence for those plants. Isolation is the easiest way of dealing with a positive test result. But thinking about how a virus spreads will also help. Viruses are spread by cross contamination. We have talked about tools... but insects are probably the most uncontrollable part of the equation.
I HATE bugs!
I just ordered a boatload of alcohol wipes to help me deal with the fall outbreak of scale.
I have never seen any indication of viruses in my orchids. There may be a virus or two out there (in the GH). But I'm not going to go look for any either. Ignorance is bliss.
