Cannabis plants need temperatures between 70 to 82 degrees Fahrenheit and high levels of humidity to properly grow. If the temperature is too hot, the plants risk of over-heating and severe damage. But what is too hot when it comes to cannabis plants? Is 82 degrees too hot and worth worrying about? To analyze the risks of over-heating cannabis plants and answer this question, one must first understand the importance of temperature, the effects of over-heating, and the preventative measures that can be taken.
Temperature plays a vital role in the growth of cannabis plants. At highs lower than 70°F, cannabis plants will not grow, and at temperatures higher than 82°F, photosynthesis can be stifled and plant growth can become stunted. Any sudden temperature changes can cause extreme distress for these heat-sensitive plants, and any consistent temperatures outside of this range can lead them to become seriously damaged.
If temperatures soar above 83°F, the cannabis plants can become increasingly vulnerable to “overheating.” The effects of overheating cannabis plants can vary from an early death to a decrease in essential nutrients, flavonoids, and bag appeal. To avoid these risks, it is important to understand what temperatures are best and to have precautionary measures in place, such as a way to ventilate the grow space and a thermometer to the track the levels.
Determining whether 82 degrees is too hot for cannabis plants to handle can be difficult, as factors such as humidity play a role as well. For example, cannabis plants may not suffer when subjected to temperatures of 82°F if the humidity level is low. Conversely, high humidity can nullify any perceived risk, as it allows cannabis plants to better tolerate heat. Therefore, the combination of heat and humidity must be scrutinized.
Fortunately, there are several warning signs that can be used to identify if a cannabis plant is heading towards being overheated. These signs include leaf curling, discoloration, fading, and/or yellowing of the leaves. If any of these signs appear after a temperature rise, the grower must act quickly and make the necessary adjustments.
In conclusion, 82 degrees is not necessarily regarded as too hot for cannabis plants, provided the humidity level is well-balanced. Still, the safest practice is to keep temperatures consistently in the 70 to 82°F range. Growers should remain vigilant and monitor the temperature and humidity of their grow space and take any associated risks seriously.
High humidity levels can help cannabis plants to better tolerate heat, even if the temperature is slightly above 82°F. In some cases, the combination of heat and humidity can allow cannabis plants to grow properly, even in environments with temperatures up to around 90°F. However, it is still important for growers to be getter their thermometers and closely monitor the temperature and humidity levels of their grow space to make sure that the plants don’t get too hot.
Having adequate ventilation also helps in controlling indoor humidity levels and can help protect cannabis plants from overheating, although it won’t entirely halt the process if the temperature is too high. Increasing the airflow and providing more space between the cannabis plants can help, but growers have to consider the fact that more space will lead to an increased heat level which, in turn, can affect humidity.
Fortunately, controlling the humidity levels isn’t particularly hard; there are several straightforward methods that can be used to adjust it, such as using fans and air conditioning systems, replacing the grow medium, or increasing ventilation. Growers should be mindful that humidity levels should be kept between 45% and 70%, with proper temperature readings to ensure that the cannabis plants won’t be subjected to any unnecessary risks.
Maintaining proper temperatures for cannabis plants is essential for successful cultivation. It is important for growers to properly ventilate their grow space and make sure that the temperature isn’t too high. Ideally, the temperature should always be between 70°F to 82°F. Temperatures slightly above are acceptable but should not be sustained for long periods of time.
Growers should take into account that increasing the airflow can also help in controlling air temperatures, and is also a great way to improve the efficiency of almost any ventilation system. Low-pressure air systems shovel air in the direction of the plants, which can help to keep them cool. If a grower chooses to install a ventilation system, they should select fan sizes that are adequate according to the number of plants they have.
Proper ventilation is essential in order to reduce temperature levels and keep them in the preferred range of 70°F to 82°F. Growers should ensure that their ventilation system’s fans are constantly blowing fresh air towards their plants and that the exhaust or intake ports are connected to a high point in the grow space.
Finally, there are some other solutions to cooling the grow space that do not involve the installation of a ventilation system. Using cooling blankets, chillers, and air conditioning units are all effective in reducing the temperature and creating a healthy grow environment for cannabis plants.
Modulating Heat & Humidity
In order to fully protect cannabis plants from the risk of overheating, growers need to be mindful of both the temperature and humidity levels. Cannabis plants can survive in temperatures slightly above 82°F if the humidity level is kept low, however, if the humidity is high the temperature should remain below 80°F in order to guarantee success. Therefore, if temperatures rise to 82°F, growers have to pay close attention to the humidity and take additional steps to protect their plants.
Modulating heat and humidity is an important part of cannabis cultivation and, when done properly, can help to increase the overall yield and quality of cannabis plants. If a grower suspects that their plants are becoming too hot, they should take necessary action to reduce the temperature, such as using cooling mechanisms, ventilating the grow space, and increasing the distance between the plants.
Growers must always keep in mind that they can rarely change the overall temperature of the climate, as it will always remain higher indoors than it is outdoors. This means that if the temperature outside is high, the temperature inside will follow suit. For this reason, it is important to install a thermometer and regularly monitor the temperature, especially during the summertime when temperatures naturally rise.
Strategies for Temperature Control
In order to effectively control the temperature of a cannabis grow space, one must be creative and incorporate several strategies. The most basic one seeks to cool down the environment by using a few fans that can generate enough air movement to cool the room. If the grow space is too hot and ventilation is not an option, other alternatives, such as air conditioning or cooling panels, can help to regulate the temperature.
Growers can also place the lights further away to generate more air movement and subsequently reduce the heat in the grow space. Furthermore, reflective walls can be used to distribute the lighting more evenly and help to keep the environment cool, while growers can opt to use LED lights which produce more light and less heat than traditional bulbs.
Finally, cannabis plants can be moved to a cooler part of the grow space. If the temperature is uncomfortably hot in the grow area, the cannabis plants can be transferred to another part of the room where they are less likely to become affected by too much heat. Of course, this works best for smaller grows. Larger grows may not leave much room for this type of maneuvering.
By having knowledge of the risks associated with hot temperatures and understanding the proper strategies for temperature and humidity control, growers can successfully manage their grow space and protect their cannabis plants from damage.
