The atmospheric situation within your indoor garden has a tremendous effect on the quantity and quality of a finished plant and effect the cannabis temperature. Most growers today are persistently trying to learn and master the understated environmental factors which can make a big difference in the growth and yield throughout the life cycle of cannabis indoor seeds

In discussing the environmental conditions of an indoor grow room, people are typically pertaining to temperature and humidity. Though humidity is a vital aspect, you have to focus more on cannabis temperature as it plays a crucial role in the ability of a cannabis plant to absorb nutrients and water and process light.

Temperature and Cannabis

Cannabis temperature can affect the ability of cannabis plants to photosynthesize. Likewise, the temperature has a very important role in the germination process and in the development of flowers and fruits. When the temperature falls out of the ideal range, your indoor grow room will become less efficient. This issue can even result in smaller, low-quality yields. 

Maintaining the Perfect Temperature for Cannabis Indoor Seeds in Your Grow location

One of the most crucial things that a cannabis grower like you can do is to maintain a specific temperature. This means the whole grow space will remain under the same temperature. 

Many growers use a high-intensity lighting tool, in their own grow rooms. This piece of equipment will produce excess heat from a focal point. If left unresolved, the heat produced by this equipment will make a certain area warmer than the rest of the grow space.

Keeping the temperature uniform in the four corners of your grow room is easy to achieve by creating proper airflow in the room. Oscillating fans will constantly move the air all over the room so that the warm air under the lighting equipment will blend with the cold air within the grow room.

Consistency is crucial in terms of the grow room temperatures. Cannabis plants respond well to consistency. The better you can maintain a specific temperature range, the more bountiful your future yields will be. 

To obtain the best consistency level, you can use a climate controller equipped with an air conditioner or ventilation fans. For ultimate control, air conditioners will be an excellent choice. 

The Correct Temperature Range for an Indoor Grow Room

In maximizing efficiency, try determining the correct temperature range in your grow room. This temperature is the that can maximize the growth of your cannabis plants. The right temperature is crop-dependent because the plants vary significantly in the way they react to temperature. 

The ideal temperature for growing cannabis plants indoors ranges from 70 to 80 degrees Fahrenheit or 21.1 to 26.6 degrees Celsius. Most varieties are okay with the maximum temperature (80 degrees Fahrenheit). This temperature range is suitable for the vegetative phase until the flowering stage. 

A grower with a climate-controlled grow room can use that temperature range as a beginning point when determining the ideal operating temperature. Consider how the air temperature affects a plant’s root mass. 

In many indoor gardens, cannabis plants grew in the hydroponic systems and planting containers. Changes in air temperature can significantly affect cannabis indoor seeds compared to those cultivated outdoors. Thus, you should keep in mind that higher air temperatures result in higher temperatures across the root mass of your plants. 

Temperature Change Between Daytime and Nighttime Periods

This is the so-called temperature differential. It is a vital element of controlling the temperature. However, most growers overlook this matter. Determining the grow room’s temperature when the lights are on is important. Once you determine it, you can start determining the ideal temperature at nighttime or when the lights are off. 

The ideal no light operating temperature ranges from 10 to 15 degrees Fahrenheit or 5 to 7 degrees Celsius. It is cooler compared to the temperature when the lights are on. This decrease in temperature is enough to let your plants go through the typical rest and transpiration process.

Keeping the temperature in that range serves as a protection against the pathogens like fungi and mold. In the semi-enclosed setting, a huge reduction in temperature leads to moisture problems and condensation on your plants and grow room.

For many indoor gardens, the ideal no-light period temperature is from 55 to 70 degrees Fahrenheit or 12.8 to 21.1 degrees Celsius. According to, temperatures more than 31 degrees Celsius may reduce THC potency and slow the growth of your plants. 

Seeds and Clones

Like the mature cannabis plants, clones and seeds depend on the temperature of your grow room. In fact, many seed varieties will just germinate when the temperature is constantly over the seeds’ initial temperature for germination. 

Again, every plant differs. When you start cultivating cannabis by using seeds, check the seed packets for directions. A few cold-weather shrubs can be germinated in cold conditions in which some summer plants require warmer temperatures for the process of germination.

Temperature and CO2 Enrichment

Growth rates can increase through enriching the environment of your indoor garden using carbon dioxide. However, you must increase the operating temperature of your grow room to reap the maximum benefits. 

The increase in the temperature will enable your plants to correctly process the extra carbon dioxide within the environment and increase the photosynthesis rate that boosts plant growth.

Finding the Correct Temperature

Each indoor garden varies, and there are several factors that significantly impact how your crop performs. Though you can use the general temperature range of 70 80 degrees Fahrenheit as a beginning point, finding the suitable temperature for your own indoor garden is obtainable through experimentation.

The same with other horticultural experiments, searching for the correct operating temperature takes time. It’s difficult to determine the way a little change in your garden affects the general results until you can measure your harvest. 

For this reason, it takes several garden cycles before the grower can collect sufficient data for making a solid conclusion regarding the right operating temperature.  Though the process can be a little tedious, a committed indoor gardener must have no issue documenting the temperatures and the way they relate to the plant’s growth. After all, you can always search for a new way to get the most out of your investments. 

Finding the right operating cannabis temperature for your indoor garden is one way to ensure your garden has constant growth rates and bountiful, repetitive harvests.
