Temperature Impact on Marijuana Plants

The temperature has an enormous impact on cannabis plants. For instance, higher temperatures often expedite cannabis growth, making warmer conditions more popular. That said, too much heat can also cause stress to the plants. The most popular harvesting time is Croptober

In contrast, colder temperatures make cannabis growth slower than in the warmer months. As such, many growers will grow cannabis in a greenhouse during winter. 

Cold Climate Greenhouse Cannabis

Greenhouse cultivation in a cold climate is a game-changer for winter cannabis growers. A greenhouse can protect plants from harsh weather conditions while allowing for optimal growth, enabling excellent growing conditions year-round. 

Here are some things to consider:

The Greenhouse Design

You should choose a greenhouse with good insulation properties to retain heat. For instance, double-layered polyethylene or polycarbonate panels are commonly used for insulation.

Likewise, ensure proper ventilation to prevent humidity buildup, condensation, and the risk of mold. Adjustable vents and fans help regulate temperature and humidity.

Heating Systems

You should install heating systems to maintain a suitable temperature range—especially during colder nights. The best options include gas heaters, electric heaters, or radiant heating systems.

You can also incorporate thermal mass elements, such as barrels of water or stones, to absorb and release heat gradually to stabilize temperatures.

Lighting Considerations

Lighting Considerations for cold weather growing

In areas with shorter daylight hours during winter, you should provide supplemental lighting using high-quality LED or HPS grow lights to ensure plants receive adequate light for photosynthesis.

One of the biggest downsides of cold weather cannabis growth is the lack of sunlight, so it’s critical to ensure correct lighting,  

The Soil and Growing Medium

You should use well-draining soil to prevent waterlogging, which can be a concern in cold climates. Mulching is also important. Apply mulch around plants to regulate soil temperature, control moisture, and protect roots from extreme cold.

10 Winter Cannabis Growing Tips

As winter descends upon cannabis cultivators, the challenge of maintaining optimal conditions for plant growth becomes paramount. Fortunately, with a few strategic adjustments and careful planning, winter can be a rewarding season for cannabis cultivation. 

Here are some of our top tips:

1. Strain Selection

Selecting the right cannabis strains for winter cultivation is crucial. You should choose strains known for their resilience to colder temperatures and shorter daylight hours.

Indica-dominant strains—which tend to have a shorter flowering time—can be particularly well-suited for an outdoor winter grow. 

2. Protective Greenhouses

You should consider investing in a greenhouse or cold frame to shield your cannabis plants from harsh winter conditions. 

Greenhouses provide a controlled environment, which enables you to regulate temperature, humidity, and light exposure. As a result, the added protection is especially beneficial in regions with severe winter weather.

3. Cold-Resistant Genetics

Pick cannabis genetics that are naturally resistant to cold temperatures. For instance, some strains have evolved in colder climates and exhibit better tolerance to chilly conditions. 

Remember to research and select strains with proven resilience to ensure your plants thrive despite the winter chill.

4. Soil Preparation

Adequate soil preparation is always essential for successful winter cultivation. Therefore, ensure your soil is well-draining to prevent waterlogged roots, which can lead to various issues. 

In addition, enhance the soil with organic matter to improve water retention and deliver essential nutrients. 

5. Mulching

You should apply a thick layer of mulch around the base of your cannabis plants to insulate the soil. Mulching helps regulate soil temperature, protects against frost, and reduces water evaporation. This technique can significantly contribute to the overall health of your winter cannabis garden.

6. Proper Watering

You should adjust your watering schedule to accommodate the winter conditions; however, be mindful of overwatering, as excess moisture in the soil can lead to root rot. 

You should water your cannabis plants when the top layer of soil feels dry, and consider using a water meter to gauge soil moisture accurately.

7. Lighting Considerations

Winter’s shorter days mean less natural sunlight for your cannabis plants; supplemental lighting becomes crucial during this period. 

You must invest in high-quality LED grow lights to provide the necessary spectrum for optimal plant growth. Also, adjust the light cycles to mimic natural daylight hours and promote robust flowering.

8. Ventilation and Air Circulation

Proper ventilation is essential to prevent issues such as mold and mildew, which can thrive in the cold and damp conditions of winter. 

Provide adequate air circulation within your growing space, and evaluate the use of fans to preserve a healthy environment.

9. Temperature Control

It’s key to maintain a consistent temperature within your growing space because cannabis plants generally prefer temperatures between 70-85°F (21-29°C) during the day and slightly cooler temperatures at night. 

If needed, use heaters or other heating devices to prevent temperature fluctuations that could stress your plants.

10. Pest Prevention

Winter doesn’t eliminate the risk of pests; in fact, some pests thrive in colder conditions. Therefore, regularly inspect your plants for signs of infestation, and use preventive measures such as neem oil or insecticidal soaps to keep pests away.
