I'll ask the dumb question. Is the plant in a basket where the emerging buds can make their way through the potting material. In the link are pictures of Stanhopea grown as garden plants here in Sydney, Australia. I can assure you that Phalaenopsis would not survive a year in that spot which gets some morning sun but has protection from the worst of the hot afternoon sun. Average Temperatures Summer Min 17C Max 27C Winter Min 7C Max 17C Extremes 42C High Low 2C No snow ever. Maybe you have to vary your inside out routine a bit and take your plant outside a little bit earlier in the spring and bring it inside a bit later in Autumn. Widely grown around here as a garden plant by non orchid growers. Humidity, sometimes it is other times it isn't, depends if the wind is coming in from the pacific ocean or blowing from the interior of the continent.

BN thanks for the support of the ID. Not my orchid, the owner has various types of Stanhopea growing in her garden. Moth balls! Yuk. Inga, these are big plants and are not often seen at orchid society meetings due to the difficulty of carting them about without damaging the flowers.

Stunning! Jane

The blooms are big and lovely, but It's a bummer, the flowers are so short lived, but the fragrance got my attention.
