Cymbidium Bud Blast

[Bethy]

A friend of mine has a Cymbidium that successfully spikes with lots of buds, but before the buds can fully develop, they wither, droop, and die before blooming.

The orchid grows indoors until May when it warms up, but it's early March and far too early to bring it outdoors with snow on the ground.

I know all the traditional causes of bud blast - temperature changes, watering fluctuation, pollution, insufficient light etc. It's really an enigma. Do you have any ideas?
