The Best Medical Strains to Grow in Minnesota

Between tornadoes and cold temperatures, weather conditions in Minnesota make it a somewhat challenging place to grow cannabis outdoors. The state receives around 30 to 40 days of thunderstorms in the summer. It also averages 27 tornadoes yearly, mainly around June to August.

Additionally, depending on where you are in the state, you can get fewer or more days in its growing season. It can have as few as 90 days in the north or 160 days in the southern region.

With all that said, it’s not impossible to grow cannabis in Minnesota. You just need the right method and strains to thrive in the state’s humid continental climate with its hot summers and freezing winters.

Harlequin

Harlequin is one of the best high-CBD cannabis strains to grow in Minnesota because of its ability to thrive in high humidity. However, if you want this sativa-dominant cultivar to flourish, consider growing it in northern Minnesota with its milder summers. Harlequin cannabis plants don’t handle excessive heat very well; they’ll dry up and eventually wither.

Harlequin Feminized Seeds

Harlequin is a sativa-dominant hybrid offering the best sativa and indica qualities. This strain delivers very effective medicinal uses with its reasonably high CBD levels.

Buy seeds

Harlequin is moderately difficult to grow due to its temperature and nutrient requirements. For this sativa hybrid to flourish, you must maintain a temperature of 72 to 85°F (22°C to 29°C) and ensure the plants receive plenty of nutrients. But, the effort you put into growing this strain rewards you with a considerable yield of around 14 to 17 ounces of cannabis flower per plant, with flowers boasting a high CBD content of 10 to 15%.

Strawberry Kush CBD

Strawberry Kush CBD is an Indica-dominant strain that’s suitable for growing in Minnesota.

Strawberry Kush CBD is an indica-dominant low-THC strain with high levels of CBD. It's a popular strain due to its berry taste and smell combined with a smooth high. These feminized seeds produce small, easy-to-grow plants that are perfect for beginners.
