The Effects of Different Temperature Ranges on Cannabis Growth

The effects of different temperature ranges on cannabis growth

Whether you’re growing for medicinal or recreational purposes, it’s important to understand the effects of different temperature ranges on cannabis growth. Understanding these factors can help you maximize yield and quality.

Temperature controls are one of many levers you have at your disposal when directing plants into the vegetative or flowering stages and towards your cultivation goals.

Temperature ranges

When it comes to growing cannabis, temperature is a vital component of success. Whether you’re building a grow room for your home, or you’re setting up an outdoor cannabis cultivation facility, it’s important to understand how to establish and maintain the optimal cannabis temperature for your plants.

Temperature affects all stages of the plant’s life cycle, from seed germination to drying and curing. It also affects the occurrence of diseases and insects. It has a significant impact on the quality and yield of the final product, and it’s a fundamental tenet that commercial growers must learn to manage in order to achieve maximum production potential.

As a rule of thumb, young seedlings and clones tend to grow best with moderate temperatures and humidity levels. They are also more robust to fluctuations in temperature than mature cannabis plants.

In the vegetative stage, optimal temperatures range between 20 and 30 degrees. As they get bigger, they can handle higher temps and lower humidity.

The second half of the flowering phase, however, is when your plants need to be slightly cooler in order to produce the best bud color, trichomes, density, and smell. Aim for a difference of 10degF (8degC) between day and night.

This allows your cannabis to grow longer, sturdier internodes. This will build a healthier, more balanced plant with strong leaves and shoots.

During the flowering stage, keep your plants’ temperature between 65-80 degrees Fahrenheit (18-26 degrees Celsius). This will help them to produce flowers with rich colors, as well as increased trichomes, denser buds, and a potent aroma.

To keep your marijuana plants’ temperature at a consistent level, you can use a thermometer and hygrometer to check the air temperature in your cannabis grow room. You can even set a two-stage thermostat that can control different temperatures for both the day and night.

While establishing the perfect temperature for your cannabis garden may seem like an easy task, it’s one that should be carefully monitored throughout its life. By following this guide, you’ll be able to establish the ideal cannabis climate for all your grow needs.

High temperatures

When it comes to growing cannabis, the temperatures you choose can have a huge impact on how well your plants perform. Fortunately, it’s easy to control your grow room temperature using the right grow light kits and equipment.

For starters, your grow lights are going to need to deliver the proper wattage for your strain and growth stage (see our complete grow kit selection). It’s also important that you maintain a consistent temperature and RH in your grow room.

If your plants are too hot, they can accidentally burn away terpenes and cannabinoids that are important to the final taste/smell/potency of your buds. It’s best to keep your buds at around 68 degrees Fahrenheit during flowering and 70-78 degrees Fahrenheit during the vegetative phase of the growth cycle.

Aside from affecting the quality of your buds, too high temperatures can also slow down growth and make it more difficult for your plant to reach its full potential. Additionally, high temperatures can cause your plants to develop bud rot and mold.

Cold temperatures are another problem for cannabis. This is because they can cause your plants to stop photosynthesis, which means that the leaves will turn purple and your plant may not even produce any flowers at all.

This is because the chloroplasts in your plant’s cells will not have enough oxygen to complete photosynthesis, so your plant will not be able to get the nutrients it needs to grow.

Finally, colder temperatures can affect the way your plants develop a strong root network. These roots are the main route that essential water and nutrients travel to your cannabis plants’ tissues.

These roots are also responsible for taking up the nutrient-rich air that your plants breathe. Without a healthy root system, your plants won’t be able to yield the highest-quality buds possible.

Temperature is an important aspect of every stage of a cannabis plant’s life. When you keep everything within range, your grow room will be a breeze to operate and you’ll be able to focus on other aspects of cultivation!

Low temperatures

In general, cannabis plants prefer to grow when temperatures are slightly warm (around 70-85degF/20-30degC) during the vegetative stage. During the flowering stage, temperatures should be kept low to encourage good bud development and production.

Temperatures can affect a variety of important factors in a cannabis plant’s lifecycle, including photosynthesis, water use efficiency, and transpiration. A proper temperature range allows cannabis plants to reach their maximum potential for growth and nutrient uptake.

For starters, higher temperatures encourage increased nutrient uptake by the root system and improve the overall vigour of the plant. However, these benefits can be short-lived if the ambient temperature is too hot or too cold.

High temperatures can also increase the risk of mold. This is especially true if the air is humid and it’s difficult to keep airflow going through your grow space.

Indoor cannabis gardeners should be very cautious of letting their temperatures drop below 15degC, as this will severely inhibit the growth of their crops. Additionally, cold weather can lead to the formation of bud rot, which can be incredibly damaging to your buds and the quality of your final product.

When it comes to growing a strain of cannabis, the optimal temperature range depends on its genetics. Indica-dominant strains typically grow well in cooler conditions than sativa-dominant varieties.

If you’re unsure about the ideal temperature for your cannabis crop, it’s best to consult a professional. They can help you create a perfect temperature environment for your specific strain, and can even recommend specific fertilizers that will work best with your cultivar.

During the flowering stage, you should aim to keep your temps between 80degF (26degC) and 90degF (27degC). This will help your cannabis to produce the most potent, dense, smelly, and trichome-covered buds as possible.

One of the greatest benefits of lower-temperature cultivation is that it can help your flowers to retain their terpenes and aromas. These oils are important for flavor and medicinal effects.

During the drying and curing process, lower temperatures can help to preserve the aromatic properties of your buds. But it’s important to note that the evaporation process can destroy some of these compounds, so you should only dry and cure your cannabis in an area with adequate airflow and a low humidity level.

Nighttime temperatures

During the vegetative stage, cannabis plants like temperatures in the range of 70 to 85degF during the day and slightly cooler at night. These lower temps reduce the amount of moisture that is lost through their leaves, which allows them to absorb more water and nutrients.

As your cannabis plants grow, you will need to maintain a consistent temperature in your grow room. Temperatures that are too hot or too cold will slow down their growth and have negative effects on the quality of your buds.

The temperature of your grow room also plays a role in the amount of nutrients that the cannabis plants uptake. If the temperature is too low, they will not be able to uptake as many nutrients as they need, which can lead to stunted growth.

In addition, the temperature of your grow room can affect the terpenes that are produced by your cannabis plant. These terpenes have the ability to influence the color of your buds and leaves.

While most cannabis strains only produce green buds, some plants can also produce pink, purple, or blue buds. However, this is only possible if your plants have the genetics for these colors.

If you want to produce these colored cannabis buds, you can make an effort to maintain a lower nighttime temperature in the last few weeks before your harvest. These lower temperatures can help your cannabis buds develop beautiful purple, pink, or blue hues!

When growing indoors, you should use a thermostat to control your room’s temperature. The temperature of your room should be between 65 and 80degF at all times, but it is especially important to keep the nighttime temperatures slightly lower than during the day.

The lower your nighttime temperature, the more likely it is that your cannabis will grow faster and healthier. A cool nighttime temperature can also encourage trichome production on your buds.

Using a timer to switch your grow light on and off will help to equalize the temperature of your grow room between day and night. This will allow your plants to get the best possible balance between heat and light, and can increase the number of buds that you produce.
