Thanks for that detailed information Robert. Are those temperatures you quote (= 12.8C to 15.6C) daytime or minimums (night)? My problem with these types of plants is I'm equatorial lowlands, the average minimum for the coldest month is about 16C, the average maximum for the coldest month is 32C. This year we had our coldest winter on record but still no flowering from H. papilio. But they grow well and still keeping producing young pups.
I have a room in the house which has constant airconditioning so I can safely store photos, documents and books (plus a few other odds and ends). The aircon acts like a dehumidifier, but it's set to 20C (68F). The window gets morning sun and reasonable light during the day. The only problem might be the lack of humidity. But I'll give it a try. Thanks again.
