Entity integrity is one of the primary rules of effective database construction. It refers to the process of enforcing a primary key for each table in a database, where the key must be either a row or a combination of rows that are unique non-null values.
If you use Senate Bill 420 as a general guideline (SB420) then you can have 1 mother plant, 12 immature plants, and 6 mature plants. I highly recommend having your medical marijuana recommendation or a copy of next to the plants.
The only thing left to do is get the paperwork to the appropriate state government agency (in Michigan it is MDCH). You are now in the medical marijuana club, medicate yourself responsibly!!!! The limits in Michigan are 2.5 dried ounces and up to 12 plants in an enclosed, locked facility (no outdoor gardening!). In Oregon, per card, we can have up to 24 dried ounces, 6 mature plants, and 18 immature plants.
