Cultivation is by a qualified patient cultivating marijuana pursuant to Section 11362.5 of the Health & Safety Code if the area he or she uses to cultivate marijuana does not exceed 100 square feet, at full plant maturity, per legal parcel, and he or she cultivates marijuana for his or her personal medical use and does not sell, distribute, donate, or provide marijuana to any other person or entity.

b. The 100 square feet limitation is imposed regardless of the number of qualified patients residing on the property, participating directly or indirectly in or benefitting from the cultivation.

c. For purposes of this subsection, the area used to cultivate marijuana shall be measured by the aggregate area of vegetative growth of live marijuana plants at full maturity on the premises.
