Humidity refers to the level of water vapor in the atmosphere. Usually humidity is expressed as a percentage. It is important to keep track of the level of humidity in a room, because whether high or low, humidity has its effects.
The level of humidity has diverse effects on human beings, animals and plants. One of the plants affected by humidity is marijuana. When the humidity is low, evaporation happens very fast leaving the marijuana plants dry and in need of more nutrients and water. The marijuana plants will therefore have to absorb more water and nutrients to supply the one lost during evaporation.
However, in case the rate of evaporation is too high, the stomata will close in an effort to protect the cannabis plant against dehydration. Since the stomata are closed, the plant will not be able to absorb any nutrients or water hence leading to stagnation in its growth. It is for this reason that most weed growers use devices like hydroponic humidifier to control the humidity in the weed grow room. However, before using a humidifier, you need to know the amount of humidity in the air. This is where the hygrometer comes in.

Buying guide: Factors to consider when buying a hygrometer
There are so many factors that you need to consider before picking a hygrometer. This is because the hygrometer you choose has to meet your needs. The following are some crucial factors you have to consider before making the purchase.
Accuracy
Accuracy has to be on top of your list because it is the most important attribute of a hygrometer that you should be on the look-out for. For instance, if your hygrometer is not accurate, your cannabis plants are going to suffer the consequences and you may end up suffering huge loses simply because the hygrometer is not accurate enough. However, when you have an accurate hygrometer you will know when to use weed humidifier to control the humidity levels.
When you look at the models reviewed above, you will notice that they all have different accuracy ranges and ratings. The most accurate hygrometer has a sensor accuracy rating of +/-1%, but a hygrometer with a sensor accuracy rating of up to +/-4% can also work well.
Ease of Use
A hygrometer that is not easy to use is not beneficial to you even if it has so many features. This is because you will end up trying to set it up rather than getting the readings. A good hygrometer is one that is extremely easy to operate. To know whether a hygrometer is easy to use, be sure to check on the user interface before purchasing it.
Another factor that makes a hygrometer easy to use is a large display. You need a display that lets you read it easily even from a far distance, a display that even elders can read with ease. In addition, the buttons and controls should also be easy to use.
Certification
Certification by The National Institute of Standards and Technology (NIST) is another factor that you need to be on the look-out for when selecting your hygrometer. This will also help you pick an accurate hygrometer because a hygrometer that is certified by NIST is a reliable and accurate hygrometer. In addition, if you are a weed grower, a NIST certified hygrometer would help you pick the best deep water culture for your plants.
Remote Monitoring
In today’s world, internet is everything. People are so busy that a device which lets them carry on with their lives is very much welcome. The same goes for hygrometer with internet connection. With such a hygrometer, you will be able to monitor the temperature and humidity changes in the grow room or any room in your home no matter where you are.
Among the above hygrometers, there are models, which let you read the hygrometer while you are far away. These are the models that I would recommend you to go for because you will be able to avoid irreversible damages when you have such hygrometers.
Other features
Other than the factors listed above, the other features that you can also consider are the multiple mounting options, the recording of minimum and maximum temperature and humidity readings, and if you intend you get a hygrometer for the outdoors, then you should consider getting one with a rugged design to enable it withstand harsh weather conditions.
Conclusion
A good hygrometer will help you monitor the humidity levels in your room with ease. This will help you avoid causing damage to the property or possessions that you treasurer most such as your weed in your grow room.
Picking the best hygrometer is not an easy job, but with the above review of the best hygrometers, I believe you now have the knowledge to make the right choice. Be sure to take your time when picking the best hygrometer for you.
