you would have to ship it over night....get a good strong clone...then i'd use those little flower water pods you get on flowers from a flourist sometimes...that might work. I don't know it would be really iffy if they would make it i think
1 liter bottle(s) to make a sturdy container. I think the thread aknight3 is speaking of uses this with cuttings wrapped in wet paper towels or something, re-cut and root upon arrival. They use this to store cuttings in crisper of fridge in case you need to close shop and go on vacation.
You could totally use this for rooted clones as long as the mass of the medium is secured. Some sort of insulation would be smart to protect from extremes.
Pretty sketchy on who you could trust to ship...FedEx has been featured on CNBC's "Marijuana inc." so you can expect them to not enjoy the negative publicity...not that they were cool before as I do not know.
Lastly, be careful about the topic in general as there was a warning from the staff that any talk of trading of seeds or clones would mean being banned from the site due to this being a legal problem for the site.
I believe there is a thread on here were a guy ordered some from a site online and got them through the mail. Pictures were put up and it was wrapped in a newspaper. I'll see if I can find it and post up the link.
