The Best Strains to Grow in Maine
Growing cannabis outdoors in Maine can be tricky due to the state's humid continental climate. It's essential to choose the right cannabis strains that can withstand humidity and temperature shifts.
There are a few factors to consider when growing cannabis outdoors in Maine. The biggest is Maine’s humid continental climate and its humidity and temperature shifts that limit your options. It's a difficult climate, so it’s essential to understand which cannabis strains grow best.
During the summer, Maine experiences warm and occasionally humid conditions, with daytime highs reaching 75 - 85 degrees Fahrenheit in July and the high 50s overnight. Winters are harsh in the Pine Tree State, with cold and snowy weather in the North and West parts. However, the coastal areas tend to have slightly less severe winters due to the Atlantic Ocean.
Despite Maine being particularly hot in July, the state tends to significantly cool down in the lead-up to fall, making outdoor cannabis cultivation difficult for many strains. Our best strains to grow in Maine list feature cultivars with hardy genetics that will withstand colder temperatures.
