Do You Use Calcium

[BikerDoc5968]

No I don't mean do you drink milk or give the chids ice cream treats.... I mean to you use/add calcium to your fertilizer? I know there are some, like the MSU stuff, that have the Ca already in there. But, for those of you who may not be using something that is SO complete, do you add Ca and if so what are you using? Bone meal or what? I also understand not all chids need/require the addition of Ca...even some species/hybrids within a specific genus may not need the stuff. But what are your thoughts....I know you must have some thoughts....you can't be as brain-dead and orchidlly compromised as I am!
