What Is It Like to Grow Cannabis in the Winter?

Cannabis cultivation

Many cannabis enthusiasts have questions regarding the ability to grow their favorite plant in the winter. The winter climate, along with shorter daylight hours and fewer hours spent outdoors, presents a challenge to what most people consider optimal growing times for cannabis. In fact, many people tend to associate cannabis cultivation with warmer weather; however, the winter season creates its own challenges and opportunities.

Why does winter create such big differences?

Cannabis plants prefer a certain amount of heat, and the lower temperatures and colder nights of winter will likely slow down the biological processes involved in plant growth. Reduced daylight hours and less available natural light reduce the rate of photosynthesis and reduce the amount of sugars being produced by the plant. Outdoor plants are also exposed to potential frost damage and excessive moisture, which can both kill your cannabis plants in just a matter of minutes. Therefore, growers indoors rely upon a climate-controlled environment to provide the warmth and light required by the plant to produce flowers. For these reasons, winter growing is mostly done indoors, rather than outdoors.

Challenges of growing cannabis in the winter

There are generally four major challenges related to environmental factors when growing cannabis in the winter:

Less daylight hours means less available light for your plants.
Lower and inconsistent temperatures, especially at night.
Indoor heat systems cause drier air.
Inconsistent humidity, which can lead to health issues for your plants.
Increased energy consumption to keep your growing area at a steady temperature.

This is why growing in the winter is more complicated and requires more planning and attention to detail when controlling the environment.

Considerations for Light and Temperature

Light is among the most crucial aspects of the growing process for winter plants. With the shorter day lengths, there is simply less sun available for your plants, and it impacts the cycle of development for your plants. Consistency in temperature is equally important because rapid temperature drops can stress out your plants and negatively affect the quality of the plant’s final product. In terms of information, winter growing is about creating a stable environment, i.e., consistent light levels, consistent warmth, and minimizing environmental shocks.

Considerations for Humidity and Air Quality

As the temperature decreases, so does the capacity for air to hold moisture, which leads to a drier environment in your indoor growing space. At the same time, when you have air trapped within a closed space (such as a growing room), you risk having too much moisture. When either extreme occurs, it can present problems for your plants. Therefore, many of the conversations surrounding winter cultivation center on achieving equilibrium: circulating clean air, regulating humidity, and preventing sharp transitions in the environment.

Is growing in the winter worth it?

While some might view winter growing as less convenient than other growing methods, for others, winter growing is more about having control over your growing environment. Growing indoors allows you to grow at the same time every month regardless of the outside conditions. However, this method requires much more knowledge, resources, and planning than growing during the warmer months. Knowing how winter affects cannabis plants can help people to make educated choices whether or not they want to attempt to grow in the winter or if they’re just interested in learning about the process.
