manani - should you ever decide to share you find for others to experiment with,
here is a cheap way to do it. buy tiny zip lock bags used for portioning out pills.
put a bit of algae in tank water dampened paper towel, then zip it into the bag,
gently squeezing out any extra water as you close it up. you can then drop it in
a regular envelope and mail it for low 44¢ first class postage within the USA.
to Canada is 75¢
as long as you use an envelope and keep it under one ounce.
I used to ROAK moss samples this way years ago.

don't get the light thin mil type used by jewelers,
you want these thicker mil water tight pill bags. please let us all know the moment you notice
it start growing on any other PLANT matter.
