and how does calcium differs from any other fertilizer... what about those growing in S/H
do they add calcium to it as well? Im just confused because how come paphs needs more calcium
than the other orchids, or was i wrong in my assumption.

Im concerned because I never applied calcium for all of my paphs, but it seems that they are
thriving.
I used to add calcium (crushed oyster shell) in the early part of growing paphs but had stopped for while. They are still growing fine and flowering. BTW I grow mainly brachys which are supposed to love calcium.
