Since Proposition 64, it has been legal to grow marijuana for recreational use. This is provided that both of the following are true: the grower is aged 21 years or older, and he cultivates no more than six cannabis plants. The following restrictions also apply: a cultivator must follow any applicable local municipality ordinances, and a person can grow no more than six plants at a single private residence. Note that: spouses or partners sharing a residence, can cultivate no more than six plants in total. This is opposed to six plants each.
