As far as trading plants goes, feel free to bring anything and everything you have to the meeting! Just label it with the plant name and your name. What doesn't get swapped at our meeting can either be auctioned at Sunday's GCAS meeting or donated to GCAS from SWOAPE!
Java Moss should do well at GCAS as would Java Ferns, Anubias, Stargrass, Bolbitis, and any other fast growing stems anyone may have! I've only been to one of their auctions but the more common stuff (Java Ferns, Vals, and Stargrass) did much better than the rest of the stuff that was donated!
Erik - the crypts I have are the common ones, lutea, I think wendtii, spiralis, retro-spiralis etc. I'm not even sure of the exact ID's on some of them as they came in with trades! I can easily break you off some runners if you want some. I lost my two C. nurii while trying to grow it emmersed out on the deck

I knew I should've only put one out there...
I think Jack and Damon also have crypts but I'm not sure what type or if they will have any for the meeting!
