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.
Having a separate grower and be very complicated, if you can grow for your self, do it. How much medical marijuana can my grower posses at anyone time? An Oregon medical marijuana grower cannot posses more that 24 ounces of useable marijuana at any time. While the grower and caregiver also have these limits, it is a collective limit, meaning that if you, your grower and caregiver are in one car, the total you 3 can posses is 24 ounces (not 24 ounces times 3 people).
