Maine Cannabis Home Grow Laws: How Many Plants You Can Legally Grow

Can You Legally Grow Cannabis at Home in Maine?

Maine stands out from many other states because it allows adults to grow cannabis at home for personal use. Under current law, anyone 21 or older can cultivate up to six mature plants, twelve immature plants, and unlimited seedlings. You can grow them on property you own or someone else’s land, as long as you have the owner’s written permission. It’s one of the more grower-friendly laws in the country, but there are still rules you need to follow to stay compliant.

Rules for Recreational Home Grows

Maine’s home grow laws are clear about how cannabis should be handled, labeled, and secured. Every mature and immature plant must have a legible tag that includes:

• Your name
• Your driver’s license or state ID number
• A note stating the plant is being grown for personal adult use as authorized by Maine law
• The landowner’s name if the property isn’t yours

The law also says your plants cannot be visible from any public area without using binoculars or an aircraft. That means you need to grow inside a greenhouse, a fenced backyard, or a private space that keeps your plants out of view. You can legally possess up to 2.5 ounces of usable cannabis. Still, anything beyond that is off-limits unless you’re a licensed business. Municipalities can regulate where homegrown farming occurs, but can’t ban it or drop the legal limit below what the state allows.

Rules for Medical Marijuana Patients

Medical cannabis patients in Maine also have the right to grow their own plants. Registered patients can cultivate up to six mature plants, twelve immature plants, and unlimited seedlings. Patients can grow for themselves or designate a caregiver to handle cultivation. Caregivers can grow for multiple patients and choose between a plant count or a canopy limit. They’re allowed up to thirty mature plants, five hundred square feet of canopy for mature plants, and up to sixty immature plants or one thousand square feet for immature plants. Every caregiver must register with Maine’s Office of Cannabis Policy (OCP) and follow all recordkeeping and security requirements.

Where Can You Grow Cannabis?

You can grow cannabis indoors, in a greenhouse, or outside as long as it’s within a locked or enclosed space. The main rule is simple: no one should be able to see your plants from the street or a neighboring property. If you rent your home or space, get written approval from your landlord or property owner. If the land isn't yours, that approval must also appear on your plant tags.

Can You Share or Gift Cannabis?

Maine lets adults share cannabis with other adults, but it has to be a true gift. You can give another adult 21 or older up to 2.5 ounces of cannabis without payment or any trade. Selling or bartering cannabis without a license remains illegal. The same rules apply to homegrown cannabis; it can’t be sold or exchanged for anything of value.
