Another thought, why does a Phalenopsis plant (even a small one) have roots many times larger than, say, a specimen sized Oncidium? The Oncidium has massive water storage facilities and wouldn't need constant source of water, yet when water is presented it needs to drink quickly? Phalenopsis on the other hand has no water storage so perhaps the roots serve part of the storage function?

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Masdies, Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)
