Indoor Climate

Indoor climate, in the context of cannabis biology and science, refers to the combination of temperature, humidity, and air circulation conditions within a controlled indoor environment where cannabis plants are cultivated. Crucial for the optimal growth and development of cannabis, the indoor climate is meticulously managed to replicate the best aspects of the natural environment, catering to the specific needs of the plant through various stages of its lifecycle.

Temperature

Temperature is a pivotal factor in cannabis cultivation. The ideal range for most cannabis strains hovers between 70-85°F (21-29°C) during the day when lights are on, and at night, temperatures should ideally not drop below 60°F (15°C). These temperature conditions ensure that metabolic processes within the cannabis plants occur without stress, facilitating proper growth and cannabinoid production.

Humidity

Humidity levels also play a significant role in the health and productivity of cannabis plants. Seedlings and clones thrive at higher humidity levels, typically between 65%-80%, while vegetative and flowering stages require reduced humidity, usually between 40%-50% and 40%-45%, respectively, to prevent mold and mildew.

How Does Indoor Air Quality Impact Indoor Climate?

The importance of indoor air quality cannot be overstated when discussing indoor climate. Poor indoor air quality can contribute to discomfort, health issues, and lower productivity. Contaminants such as mold, allergens, and pollutants can affect the overall quality of the indoor environment and impact the well-being of occupants.

Air Circulation

Alongside these parameters, maintaining proper air circulation using fans and ventilation systems is essential to distribute fresh CO2 and prevent pockets of stagnant air that can harbor pests and disease. Controlling the indoor climate is vital for maximizing yield and potency in cannabis cultivation, as it directly influences photosynthesis, respiration, transpiration, and ultimately, the overall quality of the final product.
