Humidity is the amount of water vapor held in the air. Relative humidity is measured using a hygrometer and if you are a serious indoor gardener, this equipment is mandatory.
What Happens If the Air in the Grow Room Becomes Too Dry?
Dry air results in your plants losing more water when respiring than in moist air. This reduces the overall moisture content in your weed. If the environment gets too dry (low humidity), your plants lose more moisture than they can regain through their roots.
If this happens, your plants close the pores in their leaves to minimize water loss. It is an effective tactic, but it means they receive less CO2 from the environment. The result is cell death within your cannabis plants.
It is tempting to think that you can just water your plants more often in dry conditions. However, you will end up over-watering the soil and reduce the amount of air in the growing medium. Your plants will suffocate and become more likely to develop root rot.
How to Control Humidity in the Growroom?
To answer the question, “Do I need a humidifier?” growers first need to monitor humidity readings in the growroom by using a hygrometer, a.k.a. a humidistat. The necessary humidity range for most indoor crops lies between 3-55%, with an ideal target range of 40-45%.
Humidity rising above 60% can lead to molds, mildews, and other unwanted biological growth. Furthermore, high humidity prevents plants from properly taking in CO2, preventing efficient photosynthesis. In this case, a dehumidifier for grow room can be used to lower the humidity to an appropriate level.
Humidity falling below 30% can lead to reduced transpiration capabilities, which slows growth and prevents efficient photosynthesis. In this case, a humidifier for plants or ultrasonic fogger can be used to raise the humidity to an appropriate level.
Growers can achieve these results economically by placing the device on a timer and monitoring resulting humidity levels, or if your budget allows, a hygrometer controller can be used to trigger the device only when needed.
