Why humidity in your grow room is so important to your cannabis cultivation

Humidity is an important factor to consider when cultivating cannabis. It plays a crucial role in the growth and development of the plant, as well as the overall quality of the final product.

One of the main ways humidity affects cannabis cultivation is through its impact on the plant’s transpiration rate. Transpiration is the process by which water is absorbed by the roots and then released into the air through the leaves. High humidity levels can slow down the transpiration rate, which can lead to a number of problems. For example, if the humidity is too high, the leaves may become droopy and the plant may be more susceptible to mold and mildew.

Another way humidity affects cannabis cultivation is through its impact on the plant’s metabolism. High humidity levels can cause the plant to use more energy to regulate its internal temperature, which can lead to decreased growth and development. Additionally, high humidity levels can also lead to poor air circulation, which can cause the plant to become stunted.

In order to ensure optimal growth and development, it is important to maintain the proper humidity levels during the different stages of cannabis cultivation. For the vegetative stage, the ideal humidity level is between 40-60%. During the flowering stage, the ideal humidity level is between 50-60%. And during the drying and curing stage, the ideal humidity level is between 45-55%.

To control humidity during cultivation, growers can use a humidifier or dehumidifier. They can also make use of proper ventilation, air exchange and air conditioning systems. Using proper curing methods after harvest can also help to maintain the ideal humidity levels for the final product.

Overall, humidity is an important factor to consider when cultivating cannabis. By maintaining the proper humidity levels throughout the different stages of growth, growers can ensure optimal growth and development, as well as a high-quality final product.

When selecting a dehumidifier for a cannabis cultivation grow room, there are a few key factors to consider:

Size
The size of the grow room will determine the size of the dehumidifier needed. A larger grow room will require a larger dehumidifier with a higher capacity for moisture removal.

Moisture Removal Rate
The moisture removal rate, usually measured in pints per day, will determine how quickly the dehumidifier can lower the humidity levels in the grow room. A higher moisture removal rate will allow the dehumidifier to lower humidity levels faster.

Energy Efficiency
Look for a dehumidifier that is energy efficient and has a high SEER rating. This will help to keep energy costs down and make the dehumidifier more environmentally friendly.

Features
Some dehumidifiers come with additional features such as automatic shut-off, a built-in humidistat, and a washable filter. These features can be useful for controlling humidity levels and for ease of maintenance.

Quality and Durability
Look for a dehumidifier that is built to last and is made from high-quality materials. This will ensure that the dehumidifier will be able to withstand the demands of a grow room environment and will last for a long time.

It is also worth considering to look for a dehumidifier that is specifically designed for grow room or greenhouse use. These types of dehumidifiers are built to handle the high humidity and temperature fluctuations that are common in grow rooms and will be more effective in maintaining optimal humidity levels.

Ultimately, the best dehumidifier for a cannabis cultivation grow room will depend on the specific needs of the grower and the size and conditions of the grow room. It is recommended to consult with an expert in the field or with the manufacturer before making a purchase. Our team has extensive experience growing cannabis and is ready to answer your questions.

For humidity control in your grow rooms, we highly recommend the Quest brand of dehumidifiers. 

The Quest 506 is the cannabis industry’s first 500-pint dehumidifier and a powerful and flexible workhorse.

The Quest 335 is the most efficient dehumidifier we have ever found. To prove it, Quest allows cultivators to calculate their savings with their own data using its Cost Savings Calculator.

We favor these two models so much that we named them as our Top Picks of The Year.
