Acidic MSU-RO Solution Precipitates

I think orchid growing is science - probably scientifically analytical observation, more than anything - but we just haven't learned it well enough yet!

Don't forget; science to the uneducated looks like magic!

I am grateful for the folks that spend their time researching and just plain thinking about these things, and sharing them like this, as they realize that there are no hard-and-fast answers to orchid-culture questions that start with "what's the best...".
