Vacation care

[Sevelina]

I have several orchids in planted in net pots with sphagnum moss and a peanut or two in the middle. They dry out pretty quickly, and I water them every 2-3 days, by which point the moss tends to be pretty crunchy.

My question is, I'm leaving on vacation for a week starting Tuesday, and wanted to see if dropping the net pots into an outer pot and leaving some water in the bottom of the outer pot (not touching the moss) would be a reasonable solution to prevent the moss from drying out too quickly, and to retain some humidity while I'm away. My concern is that this may invite mold? I'm attaching some pics of what that would look like.

I also have a mounted mini orchid (an experiment), which I spray with water every day, usually twice (third picture). It might not survive an entire week, so I would welcome any tips on how to deal with mounts when leaving for an extended period of time. I'm thinking of wrapping it with water-saturated moss, but I think it would still be too quick to dry out. I could also unmount it and put it into a regular pot permanently, since watering it every day is a pain in the, and I'm not sure that it's doing too well, even though it's sending out a whole bunch of roots and there's a new leaf coming out. In the picture, the super-wrinkly roots are from when I bought it, and the new medium-wrinkly roots are new. Does it look like it would be happier in a pot?

Any tips and experiences would be most appreciated, thank you!
