I try my best to keep up on S/H conversations on several orchid forums, but some folks - especially those that travel - may have problems getting to a browser, so I have set up a mailing list so that we can share our experiences to help each other via email (which many can even access via their phones).
If you are interested in joining the list, please follow the instructions here:
Help Me with a Semi-Hydroponics Issue!!!
Please note that there will be no archiving of the list messages, so if you want to browse others' questions and responses, stick to forums like this one.
I am hosting this one myself, rather than using freelists.org, as do "orchids", "orchidphotos" and "orchidhelp".
