Cannabis plants can handle small fluctuations in terms of temperature. But to get the best results, consistency is key. If you’re growing outdoors, temperatures during the day could be more unpredictable because of the heat and humidity, so you’ll need to keep a more watchful eye. Nighttime temps tend to be cooler and more predictable, so you shouldn’t have that many problems. Growing indoors can be a lot easier because you have the help of temperature controls and modulators to give you the consistency that you need.
