Growing cannabis indoors has increased ever since it has been legalized in many countries. One of the few problems to fight in growing indoors is humidity, a very important factor when growing cannabis. Humidity plays a big role in the growth of your plant.
In this article, we will help you decide which is the best humidifier out there that will fit your need for your grow room.
Importance of Humidity
At every stage of growing cannabis, your plant demands constant water intake. The amount of water they need adjusts based on the humidity level in the room. If the level of humidity is high, the plant will use leaves for absorbing moisture. If the temperature inside your grow room is hotter, then it can hold bigger amounts of moisture. As a result, the plant will use less water from the roots. In case the humidity level is low, the plant will drink more water from the roots.
As the humidity changes how much water your plant intakes, it also affects the nutrients your plant takes in (for the best humidifier level controller, read this article). When you are in control of the humidity level, you can have control over your plants nutrient consumption.
These problems may occur if you did not follow the humidity level. It might include:
- Not enough nutrients will turn your plant brown
- Bud might rot or mold
- White powdery mildew
- The growth of your plant will be slower
