'What Orchids Eat', importance of calcium

[Ray]

David, the formula was devised with the help of a professional plant nutritionist who had never read Rick's article or knew one was in the works.

It was based upon scientific articles and textbooks I have referenced in the past.

I cannot speak for anyone else, but the long-term negative impact of excessive potassium exposure to orchids is nothing more than speculation in my mind. However, as I have stated more than once, other - unrelated - scenarios involving the interference of potassium in natural and chemical systems do lend a modicum of potential credibility to the theory, which is why I'm willing to experiment.

You are certainly free to have your own opinion on the matter, but I fail to see why you think I don't, and choose to fight it so vehemently.
