Temperature day/night cycles for cannabis: 22–26°C during the day, 18–22°C at night with 4–8°C difference for healthy growth and optimised internodes.
Optimum temperatures: day 22-26°C, night 18-22°C. A temperature difference of 4-8°C promotes internode stretching. Too high temperatures: stress, reduced trichome production. Too low: slow growth, nutrient uptake problems. Automate heating/cooling, ensure even distribution in the room.
The ideal daytime temperature for growing cannabis is between 22 and 26°C.
At night, the temperature for cannabis plants should be between 18 and 22°C.
A temperature difference of 4–8°C promotes healthy growth and optimizes the internode elongation effect in cannabis plants.
