I thought I'd start a thread with lists of common orchid-lingo acronyms and what they mean.
Things like NoID (although there's a whole sticky on that one), phal., catt/cat, the numbers for fertilizers (like 20-20-20 and even explain NPK), S/H, moss types,
whatever acronyms and abbreviations you can think of.
Maybe this will be helpful. Maybe it's been done. >.<
