Growing Marijuana In Massachusetts

March 8, 2021

Please note: ILGM is NOT a legal adviser. Information contained in this website is intended as general introductory information only. The information contained on this website is not legal advice. It should not be construed as legal advice and should not be relied upon as such.

Growing marijuana in Massachusetts has never been more easy, especially now that it has been legalized. That said, it’s still important to know the rules to be sure you’re staying within the limits of the law.

Here are a few things that are not allowed:
Growing some place other than your home
Selling your harvest
Storing your harvest any place other than home

There is also a section on parenting while growing. Although the state clearly says you can parent and grow, it also says it is for those aged 21 and up. If you have children in your home, it may be a good idea to invest in a lock or have a designated grower outside of your home.

If you have more questions or comments about growing in Massachusetts, leave them below in the comment section. I will update this article as needed to add the most frequently asked questions as well as any other interesting information.

In 2015, the Massachusetts Department of Public Health began accepting applications on a rolling basis from non-profit organizations that wish to apply for a state license to operate a Registered Marijuana Dispensary (RMD) in Massachusetts. RMDs are allowed one location, and may have a second location for cultivation or preparing marijuana-infused products.

These applications are not a merit-based competition, but are verified for compliance and suitability, and will be reviewed in the order received. However, applications in open counties will be processed first. There is no stated limit to the number of RMDs that may be approved.

Medical marijuana

The medical program will cover the following conditions:
Amyotrophic Lateral Sclerosis (ALS)
Crohn’s disease
Hepatitis C
Multiple Sclerosis
Parkinson’s disease
Other conditions as determined in writing by a qualifying patient’s physician

It also will let certain patients designate caregivers, if they can prove they are unable to purchase from a dispensary.

Massachusetts marijuana laws

The tax is $3.50/gram, but it is only required if the weed only has at least 40 grams. When the tax is paid, the user receives a stamp. If caught with marijuana, the stamps must be produced, or there will be additional fines or jail time.

For those charges that do give jail time, Massachusetts has a conditional release program. Conditional release means that people caught for the first time will most likely not receive jail time.

High Quality Seeds

Mandatory sentences are the exception to conditional releases. Massachusetts has mandatory sentences for large amounts of marijuana (100 lbs or more).

You won’t get arrested for having less than an ounce of marijuana, so be sure to keep your possession amounts small.

My Marijuana Grow Bible has the best information on how to grow without getting caught. It is a free download, and when combined with high-quality seeds, it can result in the best personal weed stash you’d ever grown. So, whether you are a medical patient or a lover of high- quality weed, grow with confidence by downloading my Marijuana Grow Bible first.

Growing marijuana in Massachusetts

Learn to harvest marijuana from my Harvest Guide and start growing high quality marijuana in Massachusetts

Massachusetts Growing Laws In-Depth: If you’re confused by any of those rules, here’s a little more detail:
You must be 21 to grow your own marijuana. At 21 you’re officially an adult. At that age, you can drink, go to a casino and now, grow marijuana. If you’re still underage, wait a couple years to stay legal.
You are limited to 12 plants per household. One person is limited to 6 plants. Time your harvest so that you never have more than 12 plants in your household at one time.

They need 18 hours of light and 6 hours of complete darkness per day to remain immature. Once the days get shorter, your plants will begin producing flowers.

When growing indoors, you can control that light cycle. By shortening it from 18 hours of light to 12 hours of light, you can trigger the plants to start flowering.

You are limited to 6 flowering plants. Like I talked about in the previous section, the flowering stage is triggered by light. It lasts about two months. Make sure you harvest your plants on the right cycle so that you never have more than six flowering at a time.
Keep your entire harvest, and give away up to an ounce. You’re expected to keep your entire harvest, not to sell it. If you would like, you’re welcome to give some away to any adult, but you can’t give away more than an ounce.
Grow within your primary residence. Make sure you only grow within your own house. Do not plan to grow marijuana in your office or at your mom’s place. If you own a second home, whether it’s an apartment or a cabin in the woods, you cannot use that space to grow. You can grow in your garden or in a greenhouse but ensure it is properly secured and your plants are not visible without binoculars or an aircraft.
You can grow for someone else, but they must be at least 21. If you have a friend who’d like to grow marijuana but doesn’t have the space or time to do so in their own residence, you can help them out and grow at your home. However, make sure your friend is 21 or older and that you have no more than 12 plants at a time.

As you can see, most adults in Massachusetts should be able to grow their own marijuana. And for those who cannot, there is probably someone that can help you out.
