That god damned Cheese Fairy been at it again, hahaha. There is no holding her back. How about this for an idea.
So sending clones via the post is probably not the best thing unless doing it internally in your own country - next day delivery guaranteed.
I am sure you get thse things in the UK and Holland (I first saw them in the Far East in Singapore when I brought Orchids back) Basically you have a vile that is filled with water and the clone or cut flower is put into that. The vile doesn't allow water to escape. This can also be acheived with a cotton wool ball soaked and carefully bagged up around the base of the clone. Next you get a small bit of tubing (or even a bottle) and you hang a little bicycle lamp in there - we get them in Holland, they are tiny little lights you can attached to your jacket or your bike (about the size of a 1 euro coin). You could put this inside the bottle/pipe with the clone and then package and post.......
I wonder how long it would last???
