The Importance of Using a Humidifier to Grow Cannabis


You might think that growing cannabis is easy — just get some seeds, put them in soil, water them, and wait for the plant to grow. But there’s a lot more to it than that! In this blog post, we explain why using a humidifier for growing cannabis is essential if you wish to produce a large harvest.

Measuring Humidity

Humidity is a measure of the amount of water vapor in the air. When growing cannabis, it’s important to maintain a relative humidity (RH) level between 40–60%. This range will ensure your plants stay healthy while preventing mold and mildew growth.

There are a few different ways to measure humidity, but the most common is with a hygrometer. This device measures the amount of water vapor in the air and displays it as a percentage. You can find hygrometers at most home improvement stores or online.

Once you know what your RH levels are, you can take steps to adjust them if necessary. If the air is too dry, you can use a humidifier to add moisture. If the air is too humid, you can use a dehumidifier to remove excess moisture.

By keeping an eye on humidity levels, you can ensure your cannabis plants stay healthy and happy!

What Is a Humidifier?

A humidifier is a device used to increase a room’s humidity. Cannabis plants grow extremely well in environments with high humidity, so a humidifier can be a helpful tool for growers. There are many different types of humidifiers available on the market, so it is crucial to choose one that is appropriate for the size of your grow room. Additionally, you will need to monitor the humidity level of your grow room and adjust the settings on your humidifier accordingly.

Why You Should Buy a Humidifier

If you’re thinking about growing cannabis, you might be wondering if you need to use a humidifier. The answer is yes! Here’s why:

  • A humidifier can help increase the humidity in your grow room, which is ideal for cannabis plants. Cannabis plants thrive in environments with relative humidity (RH) of 40–60%, so using a humidifier can create the perfect conditions for them to grow.
  • Not only does using a humidifier help increase humidity levels, but it can also help keep them consistent. Fluctuating humidity levels can stress out your marijuana plants and cause them to produce less bud. Thus, by using a humidifier, you can keep the humidity levels in your grow room stable, which will help your plants stay healthy and produce more bud.
  • In addition to increasing humidity levels, a humidifier can also help reduce the risk of mold and mildew. Mold and mildew thrive in warm and humid environments, so controlling the humidity levels in your grow room can help prevent these problems.

So, if you’re serious about growing healthy, high-quality cannabis, then invest in a good humidifier. Your marijuana plants will thank you for it!

Optimal Humidity Levels

There’s no “one size fits all” humidity level for cannabis plants to grow. The RH range you should aim for depends on the age of your plants. For young plants, it’s best to keep the RH between 40 and 60%. It will help them develop strong roots and prevent them from getting too stressed. For mature marijuana plants, the ideal RH range is between 60 and 80%. That will help them maximize their growth potential and produce high-quality buds.

Regardless of your plants’ stage, monitoring the RH levels is important. If the levels get too high or too low, it can cause your plants to become stressed, leading to growth and development problems. By monitoring the RH levels and keeping them within the optimal range, you can help your plants stay healthy and happy.

Improve Your Harvest With a Humidifier

If you have been thinking about increasing the humidity for your cannabis plants but haven’t taken the plunge yet, I hope this article has helped you make a decision. Optimal humidity levels can make a big difference in your plant’s growth and yield. So, if you’re dreaming about getting a bigger harvest, buy a humidifier and give it a try. You won’t be disappointed.
