You should get pink blooms with multiple blooms I would think. The sepals should be a different shade from the petals. It's hard to predict what you will get sometimes. This is a mini-cattleya so you will be fine with a good windowsill and I believe they will bloom sooner. Growing orchids does not require a greenhouse, I don't have one.
