  1. Maintain A Consistent Temperature

During cold weather months, the temperature between the daylight and nighttime hours can be pretty drastic. 

So, if you maintain a consistent temperature, you will see the difference between compact and robust nodes and widely-spaced internodes. 

You have to keep the temperature fluctuation to a minimum. Try to strive for a temperature gap of 3.5F to 7F [2C to 4C]. 


This stands out to be pretty crucial during the 2 weeks to 3 weeks of the flowering time. Once the third week passes by, you can allow the variance in temperature to take place. 

But you still have to keep it in check. When you want to strive for changes in the temperature, make sure it’s not over 18F [10C]. 

If you are growing weed, engineered for the dramatic cold conditions, you must always be aware of your surroundings. The best way to think about temperature is to consider how exactly you feel. 

This means that if the weather is way too hot for you, it will be desirable for your plants, and it’s too cold for you, it’s hard for your plants. 

Temperature is something that has a massive impact on cannabis. It will affect the yield, quality, growth, and it’s overall health.

  1. Managing The Humidity

As a pot grower, you must always consider the factors related to humidity and temperature. You have to pay a lot more attention to your plants when growing them in the chilly winter months. 

Remember, warm air carries a lot of water, which leads to much higher humidity. Cold air is pretty dry because it doesn’t hold much moisture. 

This means that cold air contains less humidity. 

The RH or relative humidity to maintain an excellent growing ecosystem will be based on the plant’s stage. When the plants are pretty young, you must keep the humidity levels between 40% to 60%.

Are you facing some issues obtaining the correct humidity during the cold? No problem, follow the steps below, and you will be alright. 

  • Utilize a spray bottle to add water into the air. 
  • Go for a large capacity humidifier as it will be worth the investment. 
  • Moisten up the surface of the soil, but avoid over-wetting it. 
  • Drape a damp towel or a cloth around the grow space. 

Remember, plants become vulnerable to numerous molds during cold weather. So, if the ecosystem is way too damp, molds will start growing, for which you have to be pretty careful.

  1. Make Sure Not To Overfeed Your Cannabis With Nutrients

Managing the nutrients correctly stands out as the foundation of marijuana cultivation. 

Maintaining your cannabis plant without under-feeding or overfeeding stands out as a skill that magnifies the experience. 

But if you are an outdoor grower, there are several things you have to be aware of. Cold air is dry, and the plant will compensate with the great nutrient or water uptake. 

On the other hand, when the soil is rich in nutrients, it will give birth to a bit of nutrient burn, which you find visible on the tip of the leaves. 

When the temperature goes below 10C, the plant cannot absorb proper nutrients and will not obtain appropriate Phosphorous. 

Indoor growers must opt for an electrically heating mat that will stop the root zone from becoming way too cold. 

  1. Timing Is Essential

Climates in the north have short summer days that last only around 8 weeks to 10 weeks. This is one of the reasons why so many outdoor cannabis growers choose indoors when growing the plants. 

All the seeds will sprout when placed inside and begins to grow after they are placed outdoors. After they are placed outside, they get to obtain natural sunlight during the flowering and vegetative stages. 

Also, the harvesting will take place right before the unfavorable climatic conditions make an entry. When the locale forces a race against the time, try to opt for a cannabis variety with a short flowering stage.

In this modern time, there have been so many different kinds of lights available in the market. So, the cultivating lamps moved towards LED lighting options.

They stand out as a perfect option because they are much energy-efficient and lessens the heating cost. The only problem is in the low wattage, which is emitted from the lights.
