A registered medical marijuana patient has the right to grow six plants while only three of them may be mature at a time. This is different however if a patient chooses to designate a medical marijuana center as their provider. The patient and the medical marijuana center may grow six plants collectively with three of them being mature. If a patient wishes to grow and also name a medical marijuana center as their provider, then the patient should communicate with the medical marijuana center so that plant quotas may be adjusted accordingly.
