I need some advice. As way of belated introduction (I have posted here before), I have collection of around 40 orchids mainly phals, mini-catts and oncidiums and have been "orchiding" for about 7 years now. Some of the collection are mounted. I need to go away for a week. What do people do for their plants when they go away? I prefer not to get a house sitter/plant waterer if I can help it.
