Thanks for the info. Both replies are quite encouraging.
The main problem I have is winter, not summer. Because it is so cold outside here during the winter (I'm close to the arctic circle), I can't open the windows during the winter. The apartment is warm and dry then due to electric heating. Within about a foot of unopened windows, the temperature can get around 15C / 59F which is fine but the room humidity is in the 20-30% range. With a terrarium, I can easily maintain 85% humidity and good internal airflow, but the temp rarely drops below 20C / 68F.
Anyway, I'll try a few things for a year and see how the plants do before I rush out to purchase more. It is my first attempt at keeping cool growers, but I hope they do well - they're beautiful little orchids.
Thanks again,
Markus
