I'm not sure about aquarium plant clubs but I know there is a group about gardening in facebook. my country, Panama, is small and the only plants available are common plants, though one hobbyist did advice on how to import plants.OK, I may have made Adler jealous of our plant clubs, lol. But maybe he(?) has a fish or plant club close to him? They really are a great way to get locally grown plants & fish. & to learn about local water issues, new shops, etc. & to just talk tanks & show pics with like-minded people. There may be facebook or similar groups nearby? It's worth searching around for them.
Sometimes it helps to have other people see tank pics to offer advice on hardscape layout (we on AC can help here too). Or even to say "that looks balanced & nice!" or maybe "move that wood to the left a bit". I find that easier to do with other's tanks than my own, I tend to have a narrow focus. This pretty rock & plant or a nice piece of wood & lose the overall theme.
