The process of drying and curing cannabis flowers involve a variety of steps. From evaporating the water from the buds to drying and curing, but above all else, maintaining an appropriate temperature and humidity is the most crucial part. 

To control the entire environment for drying and curing cannabis is one of the most crucial factors in successfully harvesting cannabis. While an ideal temperature and humidity can vary across the process, make sure to maintain a temperature of 70 to 80 degrees Fahrenheit and a humidity of 40% to 60%.

To ensure an ideal temperature and humidity, make sure to buy a digital thermometer and hygrometer for temperature and humidity measurements. Now that you’ll be able to monitor the climate of your room, you must know the ideal temperature and humidity to aim for your plants.


During the process of seedling, it’s ideal to maintain a humidity level of 65% to 70% because the roots are not yet firm, so a high humidity level can allow the leaves to intake water. 

At the same time, it’s essential to maintain a temperature of 58 to 77 degrees Fahrenheit if you keep the lights on; With the lights off, 59 to 68 degrees Fahrenheit.

Vegetation Period

During this part of the process, the acceptable humidity range now shifts to 40% to 70%, alongside adjustments of 5% lower each week. You can let the temperature levels be the same or just slightly increase them.

The reason is that the roots absorb more humidity and evaporate it through the leaves, which cools down the plant to keep it from dying.

Flowering Period

At this point of curing your cannabis, you need to ensure a lowered humidity of 40-50%; this is extremely important to ensure that all of your plants are flowering to their full potential.

While temperatures should be slightly decreased, from 60 to 78 degrees Fahrenheit, it is crucial to avoid high temperatures for good flowering as anything higher could make them brittle or dehydrated.

Late Flowering

To increase your harvest’s yield, flavor, and appearance, ensure humidity levels of no more than 30-40%. With temperatures ranging from 64 to 75 degrees Fahrenheit with the lights on, to as low as 23 degrees Fahrenheit with lights off.

Adjusting levels of humidity and temperature can be challenging, but it doesn’t have to be! As your humidity adjusts through the process, try the following key to ensure better adjustments in each stage:

  1. Lower Humidity
  • Use tube vents at higher velocities
  • Increase fresh and cool airflow
  • Water plants right after switching on lights
  • Install a dehumidifier
  1. Higher Humidity
  • Use spray bottles
  • Keep soil surface moist, not wet
  • Hang wet towels or clothes
  • Get a humidifier
  1. Lower Temperature
  • Keep the lights on during the night and off during the day
  • Use HPS lights for growth
  • Install an AC unit
  • Increase the airflow, allowing extraction of warm water, with larger tube vents
  1. Higher Temperature
  • Get larger grow lights
  • Place a heating mat
  • Use a space heater
  • Store hardware store materials in your grow room

Using these simple and effective tricks, you are now able to control the temperature and humidity levels while drying and curing your cannabis.
