Marijuana Cultivation in Hard Climates

Extreme weather conditions might cause distortions and growth issues in marijuana plants. Even if you can’t always avoid harsh weather, you should do your best to protect your plants. You can safeguard your plants from the risks of producing marijuana in extreme weather by reading the Seed Supreme guide to face the below conditions for your growth.

Growing in Extreme Climates:

  • Growing in Windy Climates
  • Wind protection for marijuana plants
  • Growing in Cold Climates
  • Cold protection for marijuana plants
  • Planting in Humidity
  • Keeping marijuana plants dry
  • Marijuana Growing in Hot Climates
  • Heat protection for marijuana plants

Growing in Windy Climates

The impact of solid winds might stunt the growth of marijuana plants. However, wind damage can quickly throw a developing plant under too much stress. Consider the location, soil nutrient level, and seed quality before relying on the wind to promote marijuana plant growth.

Wind protection for marijuana plants

With the help of a windbreak, you can protect your plants from damage. Making a rope and stick fence, or tying plants to posts in the ground, are two options. The disadvantage is that such plants will compete for soil nutrients, sunshine, and water.

Try clipping your marijuana plants. This will likely reduce your harvest, but the plants will adapt and branch more densely, improving flowering.

Growing in Cold Climates

Unexpected colds might harm marijuana plants. Cooler temperatures merely prevent pests, which is the only benefit. In the mid-60s (18*C), throughout the day, plants grow slowly until they stop growing ultimately. If temperatures drop below 40°F (5°C) at night, tissue damage may result. There’s a difficulty when the temperature dips below 45°F (7°).

Cold protection for marijuana plants

Your goal as a grower is to keep your plants alive until the weather improves. Most plants will survive if kept at a reasonable temperature. When the weather improves, the plants will begin to grow again.

There are a few options for temporary warmth during a cold spell.

  • Bring the plants indoors and use “passive heaters” to keep them warm.
  • Fill several dark-colored containers with water, and let them warm up during the day so they can radiate heat at night.
  • Build a temporary greenhouse using wood frames and plastic covers to retain heat (creating a greenhouse effect).
  • To avoid frostbite, utilize propane-powered patio heaters. They’ll also emit CO2 and water vapor when they burn gas. The extra CO2 will boost growth.

These ideas are simple to set up and take down when the weather gets better.

You can also wrap individual plants in Polyethylene. This will protect the plants from wind and rain while retaining some heat. Some utilize high thread count sheets. Remember that unless you offer warmth to the plants, the cold will eventually reach them. Forced air heaters can also be used, keeping the temperature below 70°F (21°C) and using fans to distribute the heat uniformly.

If it’s going to be cold, keep note on your plants. Keep an eye on them and keep them warm.

Can they be left out?

What if your plants are young and the weather is cooling? How long can plants be left outside if the temperatures drop?

The answer depends on the amount of sunlight available as the Earth enters winter, sunlight intensity, and general longevity drop. Summer and early fall plants are now shaded for much of the day.

Clouds may also reduce sunlight quality. Winter plants are deprived of light and should be harvested to minimize loss. If the buds are too young to smoke, they can be made into kief, extracts, or used in cooking.

If the weather is chilly, but the plants are still getting enough light, you can protect them.

Planting in Humidity

Drought can harm marijuana plants. Air humidity and rain are examples of wetness. The moisture in the buds allows molds like Botrytis to flourish. Wet bud crevices might be challenging to dry out due to moisture retention.

Keeping marijuana plants dry

Keeping plants dry helps them resist dampness. The plants won’t be bothered by the rain if moved or enclosed. Heat (up to 70°F or 24°C) in the confined space may help protect the plants and dry off the buds, preventing mold growth. A fan can also assist in circulating the heated air.

In this case, treat the plants with an anti-fungal like potassium bicarbonate or Serenade before the rain to protect them from fungal infection. Consider plucking the plants straight away if heavy rain is forecasted, so they don’t mush up. A variety with looser, dryer buds may be more suited to humid conditions.

Marijuana Growing in Hot Climates

A hot, dry atmosphere is ideal for outdoor marijuana cultivation for many growers. When it’s hot, you can cultivate all year without worrying about mold. The plants also benefit from the sun’s powerful light, promoting bud creation. But an dry climate brings its problems, including drought and heat. This generates parched soil, which is problematic for water-loving marijuana plants.

Too much heat can kill a crop, leaving you with little to harvest. Fortunately, there are solutions. The goal is to keep the plants cool and hydrated.

Hot weather difficulties include:

  • Heat kills marijuana roots, especially young plants. In dry areas, quicker evaporation might result in complex, cracked soil. Left unchecked, hot, dry upper soil can burn roots and kill plants.
  • Heat stress is a prevalent problem in hot climates. In favorable circumstances, the marijuana leaves may cup or curl. You may see wilting or drooping. If ignored, the situation may worsen, and the plants may die.
  • Hot and dry areas often have long day cycles and short night cycles. Cannabis plants need at least 12 hours of darkness to blossom. Thus this can be problematic. Unsuitable light and dark cycles may affect the crop.
  • Desert-like temperatures can cause burnt roots, heat stress, and irregular light and dark cycles. Fortunately, there are several solutions to these issues besides proper hydration.

Heat protection for marijuana plants

In hot temperatures, avoid letting your growing medium dry out. Plants need a lot of water when it’s hot. They’ll be dried by the end of the day if they don’t drink. Water your plants early in the day and rehydrate them frequently throughout the day. Wet leaves can intensify the sun’s heat and burn the plant.


The seeds we utilize are critical to the success of your marijuana production. Always Buy marijuana seeds from a reputable seed bank. Because of their origins, these strains have developed a tolerance to the sun’s rays. Of course, constant watering and shade from the intense heat help them thrive.

Final Throughts

Even in harsh conditions, marijuana can be grown successfully. It only needs knowledge and patience to keep your plants healthy. But for the best outcomes, start with the best strain. Choose a strain that can resist freezing temperatures if you live in a cold climate. If you live in a windy area, choose hardy, thick plants.

Having the solutions increases your chances of success. So, remember the advice in this post and have fun and less stress developing wherever you grow.
