If you look at what they DO get, it's almost all nitrogen, with very low levels of everything else. The Huntington Botanical Gardens has been getting tons of awards lately, and they feed almost exclusively calcium nitrate.

Do they add the calcium nitrate to pure water, or tap/well water that also contains things plants need? I also noticed they pot some orchids in mixes containing granite chips, which likewise will add small amounts of inorganic salts to the water in the container.
