I travel to see family every few months, usually for about 5-6 days. Most of my orchids can last for a week without water. The mounted orchids, I will often place a terrarium top over them (I hope open-bottomed terrariums--basically a glass case you place over plants).

Thank you Analyst; the terrarium would be a good idea for my two mounted Tolumnias.

You know, ironically I haven't put my mounted Tolumnia in the terrarium while away. I'm still trying to get to know it. I've had it for about 9.5 months and hasn't bloomed yet, but doing well otherwise.

Analyst, I have two Tolumnias which I bought 7 months ago while they were blooming; lovely little flowers. I have to soak them every-other-day to keep them moist. They seem to be doing well, but no new growth yet..... I fear my house is too dry, so have begun misting all my orchids with a hand sprayer (and rainwater) almost every day. Have seen some new root growth at crown level on some plants.

I water tol's every day and am interested in what others do with them on vacation.
