Resource Directories - Some manufacturer's and other web sites can also be found in the links below. Listings are restricted to either 1) Individual or business members own web pages, or 2) greenhouse related businesses who offer gift memberships or discounts to HGA members according to specific criteria (see link below). The printed Commercial Directory is an annotated list of 45-50 manufacturers of hobby greenhouses and solariums for those members who would rather buy than build "from scratch". Each entry gives a brief description of the product and supplementary literature available, plus the address, telephone, fax, and e-mail addresses of manufacturers. The information in the Directory is supplied by the manufacturers and is always current. The publication is available for $2.50 (postpaid) from the HGA Publications Office, 10746 NW 103rd Court, Granger, IA 50109. Inclusion in the Directory is free to the manufacturers and no HGA endorsement is intended of any product included, nor is criticism implied by omission.
