Woohoo! :D I goto san francisco once a year. And I looooove their aq stores!
I went to one near berkley, and it was heaven. New york LFS cannot compare! XD I guess those are the perks of being closer to asia :D
Moss are highly adaptable! are there any specific moss you are looking for? each moss have a very unique look and growth patter. One of my personal favorites is the peacock moss! it grows fairly fast in beautiful triangular fronds (is that the right word for it?). I get to trim it about once a month :D if you are interested, I will be more than happy to send my next trim out to you ^_^.
Moss will attach to anything porous, if given enough time. you simply have to tie it to a piece of wood or rock. and it will grow fairly well. A good current is usually preferred.
A great way to attach moss (especially to wood) is to dry start it. Which simply means to grow it in a high humidity environment without water. This can be achieved by tying the moss onto a porous material (wood, lava rock works well for me) and placing it in a sealed container where your wood will fit comfortably :). Place it near adequate lighting and mist periodically with a weak fertilizer solution ^_^. Sent from Petguide.com App
