Thanks Greg!
Rick, in my yard I've collected moss (out of the lawn, out of gutters or wherever it's found) and just laid it on and between bricks in the fall, winter and spring as I am weeding. Eventually with the rain it takes. Of course I have the same criteria for "instant" as you. Still have one rain barrel waiting to be hooked up. Took more than a year to get the foundation bricks to set it on.
