Is it legal to buy and grow marijuana seeds in Montana?

The cannabis legislation varies from state to state, so it’s essential to know what the law says about buying and growing marijuana seeds in Montana.

Is it legal to buy and grow marijuana seeds in Montana?

Is weed legal in Montana? Yes, it is—but different cannabis laws apply to medical and recreational users. Let’s look at the history of marijuana in Montana.

The Treasure State banned cannabis in 1929. The first sign of change came in 2004 when 62% of residents voted for medical marijuana for people with debilitating conditions.

Some lawmakers weren’t on board with these new laws, so they introduced the restrictive Montana Marijuana Act, prohibiting things like growing medical marijuana seeds in Montana. Attempts were made to repeal the medical marijuana laws entirely in 2011, but Gov. Brian Schweiter was against it.

Opposing views continued to shake the senate until 2016, when the Montana Supreme Court officially approved the medical cannabis legislation. This decision led to the Montana Medical Marijuana Initiative, a bill that eased restrictions, approved more medical conditions and allowed licensed patients to grow marijuana seeds in Montana.

In November 2020, the state passed the Marijuana Legalization and Tax Initiative, which officially entered into law in January 2021. This legislation legalizes recreational cannabis, allowing the possession and consumption of a maximum of one ounce of marijuana and eight grams of cannabis concentrate for anyone over 21. Keep in mind that these are private possession and consumption limits. Public use remains illegal for medical and recreational consumers.

The law also announced recreational sales for January 2022, a 20% sales tax, and possible expungement for marijuana-related offenses.

Can you cultivate cannabis in The Treasure State? Yes, all adults can grow weed from marijuana seeds in Montana. The law allows a maximum of two mature plants and two seedlings for every recreational user.

During the medical marijuana application process, you need to select a licensed provider to buy cannabis from or opt to grow your own supply. If you choose the latter, you have to stick to these maximum possession limits at all times:

  • One ounce of dried weed
  • Four mature marijuana plants
  • 12 immature marijuana plants
  • Any cannabis flower and concentrates from the above plants

If you choose to purchase cannabis from a provider, you need to remember that you can only buy a maximum of five ounces of marijuana a month and no more than one ounce per day.

Can you buy marijuana seeds in Montana? Yes, you can shop online or visit your local medical dispensary if you’re a registered patient. Adults can also possess unlimited amounts of ungerminated marijuana seeds, whether regular, autoflower, or feminized seeds.

Should you grow weed indoors or outdoors in Montana?

Before you start planting marijuana seeds in Montana, you have to make the choice between indoor and outdoor cultivation. Let’s take a brief look at the pros and cons of each option.

If you decide to grow your cannabis crops indoors, you’ll have a lot more control over every factor of your setup. You can tweak the temperature, water, humidity, nutrient intake, and light schedule to perfection. Indoor cultivation also removes the risk of pests and keeps your plants safe from external forces.

One of the biggest deterrents to indoor cultivation is the cost. If you’re a first-time grower, you might not want to splash out on dozens of items for a setup you don’t fully understand yet. Luckily, you can grow your marijuana seeds in Montana outside and also get excellent results.

Outdoor cultivation puts your plants at the mercy of Mother Nature, but proper care and maintenance can generate sky-high yields of premium buds. Grow feminized or autoflower seeds from strains with genetic resistance to pests for optimal results.

grow weed outdoors in Montana

In Montana, marijuana seeds can be grown indoors or outside. If you opt for the latter, make sure you start in the correct season and choose the best-suited strains for this climate.

Climate conditions

Due to the Continental Divide, Montana often experiences contrasting climates. The west side is typically milder with lighter winds, cooler summers, and warmer winters. The east is less humid but has frequent warm winds that break up the freezing winters.

Peak temperatures around 85℉ usually hit in July, while January has the coldest weather with an average of 0℉. Planting marijuana seeds in Montana outdoors from November to March isn’t recommended, as this is when the state sees its heaviest snowfall.

For the best results, germinate your weed seeds around April. Prepare to plant them outside by the end of June. In Montana, marijuana seeds’ crops are usually ready for harvest from late September to early October.

Here are some excellent tips to help you produce top-of-the-line outdoor cannabis plants:

  • Plant your weed seeds in the right-sized pots for easy relocation at night or when the weather conditions are unfavorable.
  • Make sure your marijuana crops have plenty of access to the sun and that there are no obstructions.
  • Use a tarp or a plastic cloche to shield your plants from rain, wind, and pests.
  • Grow your crops in raised beds for extra heat retention.
  • Choose cannabis strains that are suited to outdoor cultivation and have a high resistance to disease and pests.

If you decide to cultivate marijuana seeds in Montana inside, follow these top grower tips:

  • Install top-quality HID lights at the appropriate distance.
  • Use an organic and nutrient-rich growing medium, like soil or hydroponics.
  • Maintain a temperature around 70–78℉ through the vegetative stage and decrease it to 68℉ when your weed plants start to flower.
  • Keep up with regular trims and remove unessential foliage for optimal airflow and light penetration to the lower leaves.
  • Use training techniques like the Screen of Green or Sea of Green to increase yields and create more consistent plants.

Best strains to grow in Montana

Before you buy a batch of marijuana seeds in Montana, you need to make sure you’re choosing the best strains for The Treasure State’s climate.

Regions in the Pacific Northwest typically experience more moisture and colder weather. As such, it’s important to select strains that can perform well in cooler and wetter climates.

Best strains to grow in Montana

Since the law sets specific plant limits, many breeders opt for faster-growing strains, like indicas, that promise more frequent harvests. The shorter time also allows outdoor growers to collect their buds before the freezing weather hits.

Let’s find out which marijuana seeds in Montana are the go-to for cannabis growers.

If you’re on the hunt for a resilient and beginner-friendly option, you’ll love White Widow feminized seeds. This award-winning cultivar offers an intense yet balanced buzz of uplifting sativa effects paired with relaxing indica ones.

White Widow feminized plants typically deliver 15 oz./m² indoors and around 24 oz. per outdoor plant after 8–9 weeks from germination. When growing these marijuana seeds in Montana outdoors, choose a location with ample sunlight and plenty of space. These crops can get tall and typically emit a potent aroma, so keep them far away from nosy neighbors.

Another easy-to-grow option includes Northern Lights feminized seeds. This popular cultivar produces short plants that are pest and mold-resistant. For optimal airflow and light penetration to the lower leaves, keep up with regular trims and remove unessential foliage.

Northern Lights feminized plants flourish in various climates and deliver huge harvests. By growing these marijuana seeds in Montana in your garden, you can collect up to 31 oz. per plant, while an indoor grow can reward you with up to 17 oz./m² around 6–8 weeks from germination.
