This is straight from the FAQs of the MMCC.
The Commission has announced the names of the 15 Pre-approved Growers, however, no actual final licenses to grow medical cannabis have been issued.? The pre-approved entities are currently working through Stage Two of the licensing process, which includes extensive background investigations and regulatory requirements. The Commissioners will vote for licensure in a public meeting once compliance with the regulatory requirements is complete.
It's very plausible they already know they are approved and moved on to phase 2.
