I'm shipping mostly mosses and ferns so rather strong plants.
Shipping time from Poland to Singapore or way back takes about 10-15 days.
From my experience best result is when plants are bagged in a ziplock bags without water and air. I'm wrapping ziplock bags into newspaper and putting into bubblewrap-lined envelope.
When I was adding water or wet towels to ziplock bags I had some problems with rotting plants.
