Grow cannabis at home in Maine: city by city
The same plant behaves differently in every town: frost dates, summer heat and humidity decide when to start, when to move plants outside, and what to watch for in the tent. Here is Maine, city by city, from NOAA's 30-year weather records.
Adults 21 and over: yes. Plant limit: 6 mature, 12 immature and unlimited seedlings per adult.
Not visible from a public way; each plant tagged with your name and ID number; towns may regulate but not ban. Source: 28-B MRSA 1502. Local rules (landlords, HOAs, city codes) can add more; this is a summary, not legal advice.
| City | Start indoors | Move outdoors | Last frost (typical) |
|---|---|---|---|
| Portland | Apr 2 to Apr 16 | May 14 | Apr 26 |
Planting dates follow the rules on each city page: after the frost date that held 9 years in 10 and once nights average 45°F, and never before April 15. Weather: NOAA 1991 to 2020 normals.
