A Danish very good grower and seller and hybridizer Hans Christiansen said, when I talked about growing my orchids now indoors, that it's actually good. Less risk for fungus and especially less risk for bacterial attacks and many other perks. It's also easier, cheaper and less work than indoors.
When it's warm enough in Summer, I take my orchids outside. I still have the greenhouse, that was bought for them. But here in the winter time you have to have good covers outside around and over the greenhouse, and light, heating and so on costs money. Then you always have to go there especially to take care of them. It's good place to grow, but they can grow well indoors also. And as I said, it's easier, and cheaper, and more comfortable.
