How many plants can you legally grow in California?
You can grow up to 6 cannabis plants at home if you’re at least 21 years old. If you turn the cannabis into a product, you cannot use volatile solvents like butane or propane. Some cities and counties have specific rules for home grows, such as permit requirements or requiring grows to be indoors. The legal penalties include: For adults between the ages of 18 and 20, cultivation of between 1 and 6 marijuana plants is an infraction punishable by a $100 ticket. For adults over the age of 18, cultivation of more than 6 plants is a misdemeanor punishable by 6 months in the county jail, a $500 fine, or both.
