Ideal Grow Room Temperature And Humidity

When you grow marijuana outdoors in a suitable climate you don t have to worry as much about the weather.

Ideal grow room temperature and humidity.

By using a reliable hygrometer and room thermometer or a hygro thermometer device you can keep track of the temperature and humidity rates in your grow room effortlessly. The best grow room temperature during the flowering stage of growth is 68 75 degrees during the day and no more than 10 15 degrees cooler at night. Optimum conditions for your dry room aim for 15 degrees celsius and keeping humidity levels at 40 50. Humidity levels need to be lowered to 40 50 extremely important you can get away with 55 anything over 60 is real bad it s best to slightly lower temperatures in flowering temperatures with lights on.

Cannabis plants like about the same temperature as humans. If you were to rapidly cool down the environment to 10 c 51 f the rh would rise to 100 also known as the dew point. If you re supplementing with co2 daytime temps can be as high as 75 82 or so. As mentioned earlier temperature and humidity levels are closely related.

The best grow room temperature during the flowering stage of growth is 68 75 degrees during the day and no more than 10 15 degrees cooler at night. Should you reduce the temperature further the water in the air would begin to condensate. The ideal level is around 35 and 45 while the plants are flowering. It is much better to dry the buds slowly at a lower temperature and spend the extra 2 3 days patiently waiting until the grow room reeks of terpenes.

If your grow room feels warm or cold humid or dry that is a sign that you may want to look into changing the temperature or humidity of your grow area. Generally cannabis plants prefer temperatures in the 70 85 f 20 30 c range during the day when lights are on. Let s imagine the temperature in your grow room is 30 c 86 f with a relative humidity rh of 33. Humidity levels during the vegetative stage should be kept high between 45 and 55.

Adjusting the levels of humidity and temperature by decreasing or increasing them when needed is not a difficult task at all. During the flowering phase they should be lowered to prevent mold and root rot. 2 control grow room temperature.
