There's a new listserv, HGA-L, sponsored by the Hobby Greenhouse Association. So far the mail volume is low, but it seems that Hydroponic growers should be interested ! To subscribe to the HGA-L send a message SUB HGA-L <your name> to LISTSERV@ULKYVM.LOUISVILLE.EDU or LISTSERV@ULKYVM.BITNET. -- Steve Saunders, Nova Scotia, Canada ssaunder@fox.nstn.ns.ca
