Whether you’re brave enough to grow cannabis in winter or live in an area that’s always chilly, you’re in for a challenge. Growing cannabis in the cold is no easy feat, requiring more than just knowledge and experience. To succeed, you’re going to need the right strain—one that can withstand the frigid weather without sacrificing potency and yield. To help you get started with the right genetics, we’ve compiled a list of the best cannabis strains for cold climates.
Can You Grow Cannabis in the Cold?
Marijuana is a hardy and versatile genus of plants that has successfully adapted to a wide variety of climates; however, every cannabis strain has its limits, especially in the seedling stage. During this early period of growth, the plants need to be kept warm, with temperatures between 75 and 80 degrees Fahrenheit. So, it’s best to keep the seedlings inside and under a grow light until they reach the vegetative growth stage.
Flowering plants also can run into problems in the cold. Rain and snow can create the perfect environment for fungal infections such as botrytis. So, if you’re going to keep the plants outside, you’ll need to keep an eye on them and protect them from inclement weather.
What Type of Cannabis Is Best for Cold Climates?
Cold climates tend to have short growing cycles and plenty of snow and rain. Therefore, your best bet is to choose a strain that is mold resistant and can complete the flowering period quickly.
For growers who prefer photoperiod strains, we recommend choosing an Indica-dominant cultivar. Indicas have adapted to the mountainous regions of Asia and the Middle East. As a result, they can handle much cooler temperatures than Sativas. They also complete the flowering cycle much faster than tropical cultivars, usually reaching maturity in just eight to nine weeks.
Autoflowering cannabis strains also are an excellent option for growers in cold climates. These cultivars descend from the Ruderalis variety of cannabis—a subspecies that has adapted to the harsh conditions of Eastern Europe. Autoflowering strains can be harvested in just two to three months, so they are ideal for areas with short growing seasons.
The team at Greenpoint Seeds is currently developing a line of autoflowering seeds that will be released this spring, so subscribe to our newsletter to be notified when they are available.
