Home Grow Laws in Maine
Adults 21+ may grow cannabis at home for personal use.
Plant Limits
Overview
Maine legalized recreational cannabis through a citizen-initiated referendum (Question 1) in November 2016. The law permits adults aged 21 and older to cultivate up to 3 mature (flowering) plants, 12 immature plants, and unlimited seedlings per person for personal use. Maine's home grow provisions are among the more generous in the country when considering immature plant allowances. The state's climate features a relatively short outdoor growing season, but the long summer days in northern Maine provide excellent light for vegetative growth.
Medical cannabis patients in Maine enjoy even more generous cultivation rights, with the ability to grow up to 6 mature plants. Maine does not require home growers to register with the state for personal cultivation, making it one of the simpler states to begin a home grow. Plants must be kept in a location that is not visible from a public way and is secure from unauthorized access. Local jurisdictions may impose additional regulations.
