The interplay between temperature, humidity, and light

Cannabis cultivation requires a balance of precise temperature, humidity, and light levels. These three factors work in symbiosis to produce outstanding results.

Light creates heat, and the temperature influences humidity in an area. Understanding this relationship is essential for successful marijuana cultivation.

The relationship between temperature and humidity in cannabis cultivation

Maintaining the right balance between humidity and temperature to grow marijuana is crucial. Too much moisture and heat in the air can cause problems for plants.

Understanding VPD (vapor pressure deficit) and its importance

Vapor pressure deficit (VPD) is similar to relative humidity. They both relate to the amount of moisture in the air.

VPD measures saturation in the environment independent of temperature. It offers more accurate predictions of water loss and plant transpiration than relative humidity.

Balancing temperature and humidity for optimal growth

Cannabis plants thrive with the correct balance of humidity and temperature. The two interact closely, as warm air holds more water.

Too much moisture increases the risk of mold, pests, and disease. An ideal setup involves maintaining humidity levels with cool air. The ranges depend on different growth stages.

Seedlings prefer warm temperatures and relative humidity of 65–70%. Reduce levels by 5% each week of the vegetation stage and settle at 45–65% in the last weeks before bloom.

Drop humidity to around 40–50% when plants begin flowering. Follow these guidelines and maintain the correct temperatures for optimal growth.

How light levels affect grow room temperatures
