The Best Medical Strains to Grow in Maryland

Maryland offers a humid subtropical climate with hot, humid summers and cold, snowy winters. The average annual temperature is 12°C (55°F), with high temperatures occurring in July that can range from 26-30°C (80-86°F). It’s said that growing Cannabis in the state has its challenges, and there are some. However, that’s to be expected when cultivating cannabis in less-than-ideal conditions.

The main concern that commercial outdoor growers have with Maryland’s climate is its ‘short’ growing season that goes from May to October. Although it has 170 days between the first and last frost, it’s cutting close when growing Cannabis from seeds. Of course, there are ways around this, like growing autoflower seeds, which have a much shorter grow cycle than regular, feminized seeds.

However, with the right marijuana strains, you can grow Cannabis that fully veg under Maryland’s short growing season and cool environment. Here’s a list of the 10 best Cannabis strains to grow in Maryland.

OG Kush CBD

OG Kush CBD is an indica-dominant high CBD strain that typically flourishes in sunny places but can thrive just as well in less-than-ideal climates, making it a great strain to grow in Maryland, with its 21 sunny days and 9 rainy days per month. Just ensure you have something to protect your outdoor Cannabis plants from sudden rain showers.
