Massachusetts law allows residents of the Commonwealth to grow marijuana at home. There are a few things you should know about Home Cultivation.
- You must be 21 years of age or older.
- You may grow up to six plants in your primary residence. Be sure you harvest your plants on a cycle, so that you never have more than six plants flowering at a time.
- If more than one individual in the residence is 21 years or older, the maximum number of plants is 12.
- If you are a Registered Qualifying Patient (Patient) of the Medical Use of Marijuana Program Online System (Online System), you are permitted to grow enough marijuana to yield a 60-day supply for personal, medical use. A 60-day supply is defined as enough to provide 10 ounces of usable marijuana.
- If you rent your home, keep in mind that landlords can legally restrict cannabis cultivation. Check your lease—and if you’re unsure, ask your landlord.
- The plants must be grown in an area that is equipped with a lock or security device.
- The plants cannot be visible from a public place without the use of binoculars, aircraft, or other optical aids.
- You cannot manufacture at-home marijuana or hemp by means of any liquid or gas, other than alcohol, that has a flashpoint below 100 degrees Fahrenheit.
Responsible Home Cultivation
Lower Risk of Electrical Fires
Growing cannabis plants indoors often requires high-powered lamps, temperature controls, and expanded levels of ventilation which can overload electrical circuits and cause fires. To lower your risk of electrical fires, consult a licensed electrician to ensure you are following all relevant fire codes.

Cannabis Oil Extraction
When making concentrates, extracting cannabis oil with flammable materials, such as propane and butane, is illegal. These materials release vapors that can easily trigger explosions. Consider alternative extraction methods.
When making edibles at home, such as cannabis-infused beverages or baked goods, it can be challenging to distribute cannabis evenly throughout a product. This can make it difficult to control potency and dosage of the edible.
Keep Kids and Pets Safe
If you have any marijuana products in your home, be sure to store them away in a locked storage container and out of reach of children and pets.
