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.
