Check out gardenweb.com . You should be able to find links and advice on everything you need. I have three mangrove plants growing in a container. I've acclimated them to saltwater without a problem. Strangely enough, I purchased the plants at target 8O . Well, I should say rescued. All of the containers were bone dry when the directions say to have 2" of water in the pot at all times.
If consequence dictate my course of action, then it doesn't matter what's right, it's only wrong if you get caught.....
