We all know how important water is for plants. They need it to grow, after all. But did you know humidity also plays a big role in plant growth? Humidity is the amount of water vapor in the air. When the air is more saturated with water vapor, it creates a more humid environment.

Humidity and Photosynthesis
Plants release water vapor into the air through their pores or stomata. They open their stomata to take in carbon dioxide for photosynthesis and release water vapor as a by-product. The amount of water vapor in the air can greatly affect how well a plant can photosynthesize. The plant will close its stomata if the air is too dry to prevent water loss. This also prevents the plant from taking in the carbon dioxide it needs for photosynthesis.
On the other hand, if the air is too humid, the plant’s stomata won’t be able to open enough to get the carbon dioxide it needs. Plants like it when the air is “just right” – not too dry and not too humid.
Maintaining Ideal Humidity Conditions
The ideal humidity level during the flowering stage is between 40 and 50%. This is because the flowers need to be able to absorb water through their petals, and if the humidity is too high, the flowers will be too wet and won’t be able to absorb the water. If the humidity is too low, the flowers will dry out, and they won’t be able to absorb the water.
Dehumidifiers are important because they help control the grow room's humidity. The best way to set up your grow room for optimal humidity control is to have a dehumidifier and a humidistat. The humidistat will help you monitor the room's humidity levels, and the dehumidifier will help keep the humidity at the ideal level.
If you live in a dry climate, you may need to increase the humidity during the flowering and vegetation stage of your cannabis plants. The easiest way to do this is with a humidifier. If the air is too dry, your plants will not be able to produce enough resin, which can affect the taste, smell, and potency of your buds.
Humidity During Cannabis' Flowering Stage
The flowering stage is the most important time for cannabis growers. During this stage, the plant produces its flowers, which are the parts of the plant that contain the highest concentration of THC. The problem is that during the flowering stage, humidity levels tend to increase, which can lead to problems such as mold and bud rot.
There are a few things that you can do to decrease humidity during the flowering stage:
- Use a dehumidifier: A dehumidifier will help to remove moisture from the air, which will in turn help to decrease humidity levels.
- Ventilation: Good ventilation is essential for keeping humidity levels down. Ensure that your grow room has plenty of ventilation so that air can circulate and moisture can be removed.
- Humidity controllers: There are devices called humidity controllers that you can use to help maintain lower humidity levels. These devices will turn on your fans or dehumidifier when the humidity level gets too high and turn them off.
As you can see, there are a few key things to remember when it comes to humidity levels during the flowering stage. By following these simple tips, you should be able to keep your humidity levels in check and ensure a healthy, bountiful harvest.
