Time to learn about ideal Grow Room Air Temperature and Humidity levels for your Cannabis plants. Remember that humidity is relative to air temperature. Weed grows best in climate that resembles the places near the equator. In other words warm and humid. Temperatures should be 22-29 Celsius during the day and drop to a little below 20 Celsius at night. They should not go below 15 Celsius or above 33 Celsius if you can help it, and minimizing the size of the day-night fluctuation is very useful. Humidity isn't as straight forward. Depending on whether you have clones or vegetative or flowering plants, the ideal humidity ranges from a low of 45% to a high of 95%.
