Hello weedgrower. You can pack them up quite well in an empty 1 litre bottle bare rooted so to say with wet paper towel around them and taped up with some strong packaging tape and post. I have received many things like this and in bubble wrap and indeed posted this way for swops as well. I am sure any takers (me included), would be happy to send you the postage cost in stamps?? Let me know if you are interested.
