Varies by state. Some states don’t let the dispensaries grow they must buy from a licensed grower. Contact a lawyer or dispensary in your area and ask a few questions. If you know other growers ask them how you can get into it. Either way I wouldn’t trust too much info from a random Internet forum especially if your freedom or livelihood is on the line.
Go on the state website. They usually lay it all out there step by step. Do you have any drug felonies or assault charges? That is usually a no go in most states.
