Can Cannabis Survive Frost? Tips for Growing and Storing Cannabis in Cold Weather

Learn how to grow and store cannabis in cold weather and avoid the negative effects of frost on cannabis plants. Discover the best strains for cold climates and how to properly store cannabis in cold temperatures.

Cannabis plants are known for their resilience and adaptability to various growing conditions. However, cannabis plants can be susceptible to frost and cold temperatures, which can have negative effects on the growth, potency, and yield of the plant. In this article, we will discuss the impact of cold weather and frost on cannabis plants, as well as provide tips for growing and storing cannabis in cold weather.


Effects of Cold Weather and Frost on Cannabis Plants

Cold weather and frost can have several negative effects on cannabis plants, including:

  • Stunted growth: Cold temperatures can slow down the growth rate of cannabis plants and cause them to be smaller than usual.
  • Reduced potency: Cannabis plants that are exposed to frost may produce lower levels of THC and other cannabinoids, which can affect the potency of the final product.
  • Decreased yield: Frost can damage the buds and flowers of cannabis plants, leading to a decreased yield at harvest time.
  • Increased susceptibility to disease: Cannabis plants that have been exposed to cold temperatures may be more susceptible to disease and pests.


Tips for Growing Cannabis in Cold Weather

If you live in a cold climate and want to grow cannabis, there are several tips you can follow to ensure your plants survive and thrive:

  1. Choose cold-resistant strains: Some cannabis strains are more resistant to cold temperatures than others. Look for strains that have been bred for cold climates or have a high level of resistance to cold temperatures.
  2. Start indoors: Starting your cannabis plants indoors can give them a head start and protect them from cold temperatures until they are strong enough to handle the outdoor climate.
  3. Use a greenhouse: A greenhouse can provide a protective environment for your cannabis plants, allowing them to grow and thrive in colder temperatures.
  4. Cover your plants: If frost is expected, cover your cannabis plants with blankets or other materials to protect them from the cold.
  5. Use a heat source: A heat source, such as a heater or heat lamp, can help keep your cannabis plants warm in cold weather.


Tips for Storing Cannabis in Cold Weather

If you need to store cannabis in cold weather, there are a few tips you should follow to ensure it stays fresh and potent:

  1. Keep it dry: Moisture can lead to mold growth, which can affect the potency and flavor of your cannabis. Keep your cannabis dry by storing it in an airtight container with a desiccant packet.
  2. Avoid freezing: Freezing can damage the trichomes on your cannabis buds, leading to a decreased potency and flavor. Keep your cannabis at temperatures between 32-68°F (0-20°C) to avoid freezing.
  3. Keep it in the dark: Light can degrade the cannabinoids in your cannabis, leading to a decreased potency. Store your cannabis in a dark place to protect it from light.
  4. Use a humidity monitor: A humidity monitor can help you keep track of the moisture levels in your storage container and ensure that your cannabis stays at the optimal humidity level (between 59-63%).



Cold weather and frost can be challenging for cannabis growers, but by following these tips, you can help your plants survive and thrive in colder temperatures. Whether you are growing cannabis or storing it, it is important to take precautions to protect it from the negative effects of cold weather. By choosing the right strains, starting your plants indoors, using a greenhouse, covering your plants, keeping your cannabis dry, avoiding freezing and keeping it in the dark, and using a humidity monitor, you can ensure that your cannabis remains fresh and potent. As always, if you have any questions or concerns about growing or storing cannabis in cold weather, consult a healthcare professional or experienced grower for advice.
