When it comes to cultivating Cannabis, temperature can play an essential role in the success of the plants. Temperature requirements may vary greatly depending on the strain, growing style, and the location. This makes understanding suitable temperatures for Cannabis a complicated and indeterminate process. Therefore, one of the most frequently asked questions is: Is 50-degrees too cold for Cannabis growth?
The simple answer to that question is: no, 50-degrees is not too cold for Cannabis growth. Cannabis plants do well in temperatures ranging from 57 to 80 degrees Fahrenheit during the day. Furthermore, the plants are well-adapted to colder outdoor climates, enabling them to tolerate temperatures dipping as low as 50-degrees during their vegetative stage. That said, Cannabis plants will perform best in a more hospitable, higher temperature range.
If the Cannabis plants are exposed to temperatures near 50-degrees for an extended period, it can cause stunted growth and slow down their development. Thus, growers are recommended to provide an optimal climate that is closer to 80-degrees if attempting to maximize the production of their plants. However, this doesn’t mean growers should only aim to keep their Cannabis plants at 80-degrees.
While 80-degrees will enable the plants to grow faster and bigger, it will open the plants to a barrage of pests and other problems if any other environmental factors go out of balance. Also, the plants will likely not produce their full cannabinoid profile if they are exposed to temperatures around 80-degrees. So, properly balancing the light, humidity, and temperature during the Cannabis cultivation process is essential to ensure good health and quality.
Overall, in conclusion, Cannabis needs a temperature range from 57 to 80-degrees to reach its best performance. Even though the plants are capable of withstanding temperatures near 50-degrees for short periods, it is not recommended for extended exposure. The best practice for Cannabis cultivation is to aim for a replicable and balanced temperature near the mid-seventies. This temperature provides an optimal environment for the Cannabis plants and offers a greater chance of success for the growers.
Understanding the Impact of 70 Degrees
When designing a Cannabis growth environment, 70-degrees is a temperature range that cultivators will want to be aware of. This temperature range neither challenges the plant to its fullest capabilities nor exposes it to harm. At the same time, 70-degrees can also bring benefits to the Cannabis strain, such as providing higher and denser yields. Often, hours of exposure to 70-degrees temperatures can impact the plant in a positive manner.
That said, there are also drawbacks to maintaining an environment at this temperature. For instance, if the humidity is not properly regulated, the plants may develop foliage damage, such as burned tips. Also, the plants can become more susceptible to diseases and pests if the environment temperature is too low. Thus, to avoid any detriment to the Cannabis plant, always double-check and adjust the lighting, temperature, and humidity if necessary.
Interestingly, starting the light cycle of Cannabis plants at 70-degrees Fahrenheit may also result in higher CBD levels. This is because higher temperatures will accelerate the growth of the plants while simulating the natural environment of the Cannabis plants in the wild. In addition, this can be beneficial in late-flowering stages, helping to reduce the amount of time it takes the buds to mature.
Finally, the humidity of the environment is very important when maintaining the temperature in a Cannabis growth environment. This is because the higher the relative humidity, the less moisture the plant loses. Ideally, growers should set the relative humidity of the environment in the 60-65% range when the temperature is set to 70-degrees. This will prevent dehydration and protect the health of the plants.
The Benefits of 75 Degrees for Maximum Results
To maximize their yield, many Cannabis cultivators prefer to keep the temperature of the environment around 75-degrees. In this range, the plants will absorb light and nutrients more efficiently, resulting in a greater yield and fluffier buds. Also, keeping the environment within this range will provide the ideal conditions to maintain the plants’ long-term health. The plants should not be exposed to extreme temperatures, either too low or too high, as this can cause stunted or slow growth and may also result in lower yields.
Cannabis plants grown in a 75-degree environment will also have healthier roots, as the humidity and air temperature at moderate levels will have a direct effect on their inner biology. Furthermore, this temperature range is suitable for the development of trichome production and the overall curing process. Moreover, the slower curing rate allows more time for other compounds, such as terpenes, to develop and contribute towards an intoxicating flavor and aroma.
This range of temperature is also beneficial for the flowering stage. For example, it is recommended to keep the temperature at 77-degrees as the plants transition into this stage. In this way, the buds will swell and fur on the plant’s buds will thicken much quicker. In addition, if the temperatures is kept to this range, it will create an environment in which the plants can achieve their full potential.
Finally, Cannabis cultivators should keep a proper ventilation system in the Growing environment. This is especially important at moderate temperatures as aggressive ventilation can reduce humidity and cause the plants to lack water. Additionally, this can increase the pace of respiration, resulting in the plants losing too much moisture and leading to nutrient deficiencies or even chemical burn.
The Pitfalls of 80 Degrees or Higher
Cultivators should be aware that the environment temperature of 80-degrees or higher can lead to severe problems for Cannabis plants. Even if growers keep the plants well-hydrated, a temperature this high can cause the buds to wither and die. This is because higher temperatures also increase photosynthesis and respiration, which depletes more energy than the plant gains from the light.
Along with this, the plants become more susceptible to diseases, molds and bud rot when the temperatures exceed 80-degrees. At the same time, lower humidity and the increased respiration rate reduce the amount of nutrients, minerals, and other compounds. This can significantly reduce the flavor, aroma, and density of the flowers, and even impact the plant’s physical structure.
In addition, when the environment temperature is around 80-degrees, the plant consumes excessive amounts of energy through respiration. This can exhaust or even kill the plant, especially if it is subjected to high temperatures for a long duration. That said, growers should never leave the plants exposed to temperatures higher than 80-degrees as this can be extremely detrimental to the development of the plant.
Finally, it is also important to note that heated grow rooms can reduce the concentration of CO2. This is because higher temperatures will cause the air to hold less CO2, which can reduce the metabolism of the plant. As such, growers should attempt to keep the temperatures of their growing environment below the 80-degree mark. If this isn’t possible, an external CO2 disc is recommended to compensate the lower levels of CO2 in the air.
The Advantages of Growing in Cold Environments
Despite the many drawbacks of low temperatures, growing Cannabis in cold environments can also offer benefits that you may be missing out on. Usually, temperatures around 50-degrees will cause the plants to go into shock, however, with the proper guidance, it can lead to quality buds. This is because it will cause the plant to focus on survival and the production of cannabinoids, resulting in denser and more powerful buds.
In order to do so, certain techniques are essential. Firstly, Cannabis cultivators should ensure that their environment is not overly humid and that temperatures drop gradually to give the plants time to adjust. Secondly, airflow is also important and it should be provided alongside the heat by a fan to disperse the cold air without posing an additional strain on the plants. Lastly, the plants should be provided with an adequate amount of plant growth nutrients and carbohydrates to encourage healthy development and vigor.
Furthermore, using a Scrog or Screen of Green technique while growing in cold environments can also result in higher yields. This technique will enable the growers to maximize their canopy and produce more consistent plants with fluffier buds. Also, the growth tips of the plants will remain safe and dormancy will be resisted if the cold air is properly coordinated with light cycle.
Lastly, growing in cold temperatures also reduces the need for ventilation. This happens as lower temperatures cause less moisture to evaporate from the plants, thus reducing the need for drying agents and extractors. Overall, growing Cannabis in cold environments can be a risky endeavor, however, if done properly it can result in denser, more flavorful and aromatic buds rich with trichome production.
