How to grow a weed plant in winter and cold weather

The leaves are changing, and it’s officially sweater weather. As the climate changed, you might be wondering how to grow a weed plant in winter? 

Although marijuana is more of a summer gal, it’s possible to grow weed in the winter under the correct care. 

Want to find out how? Continue reading our tips and tricks on growing cannabis in winter and the best strains for a cold climate. 

What are the ideal growing conditions for marijuana?

Marijuana likes the same environment as your grandma. There’s a reason older folks go to Florida for the winter. Both like a climate that’s not too hot, not too cold, has plenty of sunlight and average humidity, which is why growing weed in the winter isn’t ideal. 

How to grow a weed plant in winter and cold weather

The optimal temperature for growing marijuana is from 68°F to 78°F. Typically the weed season is from late spring to early fall. 

If the temperature drops below these degrees and you’re growing weed in the cold, your cannabis plant suffers from stunted growth, a less potent harvest, and can even die. When the environment is too hot, it can lead to nutrient burn, prolonged growing, or mildew. 

Lighting is an essential factor for growing marijuana. During the immature stages, cannabis plants need 24 hours of light, which helps with photosynthesis and producing a potent harvest. 

As the crop matures, it only needs 12 hours of light. There’s only about 8 hours of sun when growing weed in the winter, and most days are cloudy. 

Weed plants love a humid room from 40% to 70%, depending on the crop’s maturity. If you’re growing weed in the winter and the humidity for weed is too low, you run the risk of a longer growing process and less resin production. 

On the other hand, mold, pests, and other pathogens appear when the grow room is too humid. 

Your cannabis plants will be as happy as grandma at her all-inclusive resort if you have these factors under control. 

How to grow a weed plant in winter and cold climates?

You’re probably thinking, well, in the United States, the northern half of the country experiences below-freezing temperatures with snow. What happens if you live here? How can you grow a weed plant in winter?

Growing marijuana indoors during winter is possible; you just have to watch all of the climate factors. Let’s look at some tips to follow on how to grow a weed plant in winter. 

How to grow a weed plant in winter and cold weather

Pick the perfect genetics

Some marijuana strains do better in colder climates than others. For growing weed in winter, look for indica dominant strains from parts of the world that tend to be cooler. 

Autoflowering cannabis strains are best to use when growing weed in winter. These pot strains aren’t dependent on light to enter the flowering stage. They’ll start flowering automatically at a certain point of maturity. 

If you choose regular marijuana seeds, your plants could get stuck in the vegetative stage until late winter or early spring. 

For growing weed in the cold, we recommend choosing an indica dominant autoflowering strain.  

Keep roots warm and up off the cold floor

To grow weed in the winter, the roots of your marijuana plants need to stay above 54°F to promote healthy growth during the vegetative stage and minimize stress. 

If you’re growing weed in the winter in a garage or unfinished basement with cement flooring, it’s best to raise your plant off the ground. You’ll lose a lot of warmth through the flooring. 

When possible, it’s better to grow weed in the winter in a place with good insulation. This way, you won’t lose a lot of the artificial heart and humidity you’re paying for to the elements. 

How cold weather affects cannabis plants

Growing weed in cold weather changes how the plant matures. The crop’s metabolism is much slower and less active. This results in a longer growing period, smaller buds, and a less potent harvest. 

Growing weed in the winter can change the color of the leaves to a purplish red. 

If you want a successful harvest while growing weed in the winter, it’s vital to keep a consistent and warm climate for your marijuana plants. 

Can you grow cannabis outdoors in winter?

If you live in a state with snow or below freezing temperatures, we don’t recommend growing cannabis outdoors in winter. 

When you live in the southern half of the United States, you can get away with growing marijuana outdoors in winter. 

How to grow a weed plant in winter and cold weather

Consider growing cannabis in a greenhouse during winter

Growing cannabis in a greenhouse during winter is the best way to protect your plants from any severe storms and conserve some heat. Even the southern states can drop under 68°F during the days and nights. 

You’ll be able to create a consistent climate in a greenhouse, which is what marijuana plants love. 

Start your plants indoors

During the early stages of the cannabis plant’s life, start growing marijuana indoors during winter. 

During the seedling stage, the crops need to be very warm and in a humid environment to thrive. This is easier achieved indoors. Once the plants are mature, you can move them to be outdoor pot plants for winter. 

Pay attention to the temperature

If you’re growing cannabis outdoors in winter, keep an eye on the cannabis temperature and grow in portable pots. 

If you know a cold front is coming through, or the temperature is going to drop too low at night, bring your plants indoors. This action can help keep your marijuana crops healthy. 

Protect from rain and snow

Similar to a cold front, if you know rain or a snowstorm is coming and you’re growing cannabis outdoors in the winter, move your plants to a safe location. 

Growing cannabis in a greenhouse during winter can assist in protecting your plants, and you won’t have to move them. 

Control humidity levels

The humidity levels range from state to state during the winter. The colder months tend to be less humid. Controlling the humidity levels outdoors is difficult as Mother Nature is in control. 

Again, growing cannabis in a greenhouse during winter will help regulate the humidity levels. 

Try to force flowering 

If you’re not growing autoflower seeds outdoors in winter, you can force flowering. 

Why do this? You can enhance the quality of the nugs and have marijuana plants at different stages when growing outdoors. 

How? You need to eliminate light with an opaque container, like a cardboard box or tarp, so that no light can get through. Your plants will go into the flowering stage once there’s more darkness. 

Best strains to grow in cold weather

Now you know it’s possible to grow weed in the winter, you’re probably wondering what the best outdoor strains to buy are.
