Seeds for a Cool Climate
Growing marijuana outdoors can be challenging in cold, damp climates. However, it doesn't need to be impossible. Cannabis can grow anywhere. If you're looking for marijuana seeds that grow in cold climate conditions, these are some of the best. A few of these in your shopping cart will last you all winter.
Marijuana has three distinct growth phases. First is the seedling stage, where plants need plenty of light and attention. Then, there's the vegetative stage. During this time, Cannabis plants grow in size and strength to prepare for flowers. Finally, during the flowering stage, they develop their cannabinoids and terpenes.
Although we want our Cannabis plants to grow as fast as possible, each stage is crucial for growing high-quality marijuana. Unfortunately, the vegetative stage only lasts if the temperature stays warm. This stage also needs sunlight. Sunlight and warm temperatures can be hard to provide outdoors in colder climates -especially during Fall.
How to Grow Outdoors In Cool Climates
For the best possible marijuana, a Cannabis plant must receive enough light during its vegetative stage. Indoors, this is easy with artificial lights. Outdoors, it is the will of nature.
The warm temperature won't hang around forever. That's why, when the timing is critical auto flowering marijuana is the way to go. The fact is, if you want to grow where it is cold, you'll need autoflowering cold weather seeds. Our collection of cool climate seeds flower quickly. These autoflowering strains reach the flowering phase before it gets too cold for them to grow.
Timing is key when growing outdoors in a cooler area. You must plant your Cannabis seeds when you know they will receive plenty of sunlight. They must finish their vegetative stage before the energy from the sun goes away. Use our Grow calendar to help calculate when that will be. If you know your environment will not produce enough sunlight, grow indoors with lights.
You Can Plant Weed in Winter
Autoflowering Cannabis makes it possible to grow year-round. The easiest way to do this is by keeping your plant indoors. However, if you can ensure mild temperatures, they can grow outside as well. Some places have mild enough temperatures for wintertime growing. Others may need to use greenhouses and heaters to prevent frost damage. Whenever you choose to plant, if cold temperatures are a concern, planning is critical auto flowers are the solution.
Autoflowering plants combine Siberian ruderalis genetics with popular marijuana varieties. This combination led to hearty, rugged plants that can survive the occasional frost. That doesn't mean all auto flowers are suitable for winter growing. However, in general, they tend to be much better adapted.
How to Know If It's Too Cold to Grow Weed
Marijuana can grow well where it's cool and survive where it's cold. In the Northern hemisphere, a cool climate might occasionally have cold September temperatures. Colder climates, on the other hand, frequently have frigid Septembers that sometimes freeze. For Cannabis strains, regular freezing temperatures are not okay. However, a hearty plant should be able to survive one day of freezing temperatures.
If your area never freezes by mid-October, you do not need cold weather plants. It's probably best if you choose one that is suitable for warm environments. If you plant Cannabis strains that are best in cold climates in a warm climate, your plant may never reach its full terpene potential.
Growing Marijuana Strains in Colder Climates
Marijuana strains that thrive in cool weather have a few similar traits. Besides having shorter vegetative periods, cold climate autoflowering seeds also need less sunlight. This one fact means you can grow these strains in cloudy conditions, such as in Europe or the Pacific Northwest.
While needing less sun helps autoflowering strains survive, it also makes them more at risk for mold. That's why the best strains for growing in cold climates are also mold resistant. Many cold-weather varieties produce hearty, mold-resistant marijuana plants. Finding them is the hardest part.
If you decide to buy marijuana seeds cold climate conditions limit your selection, but they do not make it impossible.
