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.

Key Rules & Regulations

Penalties for Violations

Growing more than the allowed amount is a civil violation for small overages, with fines starting at $500. Significant overages or commercial-scale cultivation without a license is a criminal offense. Growing more than 20 mature plants without a license is a Class C crime (up to 5 years in prison). Selling home-grown cannabis is a criminal offense with escalating penalties based on quantity.

Tips for Home Growers

1Start plants indoors in April to maximize Maine's short outdoor growing season, transplanting after the last frost in late May or early June.
2Choose cold-hardy, fast-finishing strains bred for northern climates.
3Take advantage of the generous immature plant limit to maintain a healthy rotation of mother plants and clones.
4Use greenhouses to extend the season and protect against Maine's early fall frosts.
