Introduction
The cannabis vegetative stage is a critical period where the plant focuses on growth and development. Maintaining the right temperature is essential for optimal plant health.
Optimal Temperature Range
The ideal temperature for the cannabis vegetative stage is between 70°F to 85°F (21°C to 29°C). This range allows the plant to grow robustly and efficiently.

Why Temperature Matters
Temperature affects various physiological processes in cannabis plants. Incorrect temperatures can lead to stress, reduced growth, and even flowering prematurely.
Low Temperatures
Temperatures below 70°F (21°C) can slow growth and weaken the plant's immune system. It may also cause the plant to enter a state of dormancy.

High Temperatures
Temperatures above 85°F (29°C) can cause heat stress, leading to yellowing leaves, decreased photosynthesis, and potential leaf burn. It can also promote the onset of flowering.
Monitoring and Control
Regularly monitor the temperature in your grow space using a reliable thermometer. Adjust your ventilation and heating/cooling systems as needed to maintain the optimal temperature range.
