Um, dude the *only* way to not report is to keep it under *6* medical plants that are your own. If you're growing for *anyone* else (even if not for yourself) you have to use one of the reporting sites see:
https://www.oregon.gov/oha/PH/DISEASESCONDITIONS/CHRONICDISEASE/MEDICALMARIJUANAPROGRAM/Pages/reporting.aspx
The bit you want to look at is under "MUST REPORT MONTHLY IN OMMOS" The only way around that is to have two medical growers who both live at one growing site each growing for ONLY themselves to hit the 12 plant number, any other method that gets you up to 12 (medical mature) plants means you have to report in some way, shape, or form.
