What is a hygrometer?

Also known as, a humidity meter, a hygrometer is a weather gadget used to measure the amount of moisture in the air. They are the devices used to measure the level of humidity in the air.

Besides measuring the amount of moisture in the open air, a hygrometer can also be used when measuring the amount of humidity/moisture in the soil or in confined spaces such as grow rooms. The BEST HYGROMETER is one that gives accurate readings. The following are some of the best hygrometers that are going to give you the most accurate reading.

In terms of humidity levels, the best range is in between 40 to 70%. If it’s lower or higher, your cannabis plant may suffer some issues. You have to take note, however, that the precise level of humidity varies depending on the growth stage. For instance, the sprouting stage likes to have more humidity. Following that, here are some notes about the range of humidity level based on the growth stage.

• Sprouting Stage — During the stage when seeds sprout and seedlings start to grow roots, give your plants around 65 to 70% humidity.
• Vegetation Stage — During the stage when leaves grow, slowly decrease the humidity every week by 5% until the flowering stage.
• Flowering Stage — At this stage, retain the humidity levels at about 40 to 50%.
• Harvest Stage — At around one or two weeks before harvesting, you can reduce the humidity level more at around 30 to 40%.
