Growers Licenses called Optional Premise Cultivation Licenses [OPCL's] can only be issued to Dispensaries. You can not grow and sell to a dispensary. This is all regulated through the Department of Revenue Medical Marijuana Enforcement Division.

Caregiver growers can cultivate for up to 5 patients, but are required to sell medical marijuana for cost of production. Caregivers can charge for the other required services that they must provide to patients. Cooking, cleaning, shopping, etc... but I don't know a lot about caregivers and how all that works these days. I will say that when we were caregivers we kept an attorney on retainer to help keep on the right path. Maybe that might be your first step. The Health Dept has rules on their website if that helps.

If you moved here to start a marijuana business, you might be disappointed. Shops are closing down at a rapid rate due to excessive competition and over regulation. Caregivers are giving up because of the regulations and grow site registrations required.
