Cannabis Seeds in Montana
Because the Treasure State is surprisingly 420-friendly, many people are growing themselves, and you can see many residents purchasing cannabis seeds in Montana for at-home cultivation. However, ordering quality seeds is only the first step in harvesting your favorite plant. There are many considerations to take into account.
Luckily, Herbies Seeds offers the best selection of marijuana seeds for sale in Montana – let’s cover legal and climate questions of growing in Montana before moving on to our top seven seeds ideal for this state.
Is it Legal to Buy Marijuana Seeds in Montana?
First, the good news: it’s completely legal to buy cannabis seeds in Montana for adults aged 21 and over. Better still, you can even grow them, unlike many other regions throughout the country.
Now, the bad news is that adults only get to cultivate a limited number of plants simultaneously. That said, you can find many strains that produce huge yields with one plant – we’ll get to them later. Montana consumers can legally possess up to one ounce of cannabis. Recreational cannabis sales are permitted only in counties that have opted in, but personal possession and cultivation are legal statewide. With many counties approving adult recreational use, you'll surely need a rotating stock.

Can You Grow Cannabis in Montana?
Although you can't grow that many plants, it’s legal to do so. This is excellent news for anyone who wants to buy marijuana seeds in Montana. Adults aged 21 and over may cultivate up to two mature cannabis plants and two seedlings per person, with a household maximum of double that amount if multiple eligible adults live at the same residence. Medical marijuana cardholders are allowed higher plant limits under state law. You must also keep your plants away from minors and ensure they are grown in an enclosed area and not visible from public view. While Big Sky Country is supportive, there’s still much progress to make.

What to Consider When Buying Marijuana Seeds in Montana
Although it's legal to grow in Montana, you have several considerations to take into account first. The state is infamous for its natural ruggedness and harsh winter weather. Before you start the search for marijuana seeds in Montana, reevaluate your growing setup first. Many consumers prefer to grow their plants inside, but some strains become pungent. You may need additional carbon filters or other accessories to keep them from smelling. Some strains must have their light cycle adjusted, while others don’t. Make sure to research autoflowering and photoperiod cannabis before you buy cannabis seeds in Montana to make a truly informed decision.
Climate in Montana
The climate in Montana isn’t the most ideal for growing cannabis. By mid-September, the temperatures will begin dropping, making your plants vulnerable. Will you see flowers bloom before winter, or will you lose your entire crop?
MN is also known for having different climates for the west and east sides; the western end stays mild and humid, while the east is windy and dry – you’ll need to act accordingly. The warmest month is July, usually peaking in the mid-80s°F (high 20s°C). Temperatures plummet from September to January, when it stays frigid.
But no worries – with properly chosen seeds, you’ll successfully harvest your buds. Outdoor growers in Montana should rely on autoflowers for their faster flowering times, or they could buy photoperiod strains that will finish before temperatures plummet. Consumers will likely find that Indicas and Indica hybrids will offer the best chance. Now to the best part: let’s see what cannabis seeds in Montana prove ideal for growing.
