Humidity Controller


The ideal humidity level to foster plant growth is between 50 and 70 percent. However, in summer, due to hot weather, the heat tends to absorb most of the humidity that plants desperately need for proper growth. And when the humidity level inside your greenhouse falls below 30 percent RH, the plants begin to wilt which further halts their growth process. To attain ideal humidity levels in your greenhouse, consider investing in and installing our advanced and easy to use humidity controller.

    Featuring humidity control and measuring range of 1 percent -99 percent RH, this is a user-friendly and functional 110V humidity controller designed exclusively to help you achieve and maintain ideal humidity levels in greenhouses and for industrial misting system applications.

    With this humidity controller installed, you can easily monitor and control humidity level in your desired setting without any hassle. The device provides you accurate reading and also retains data for ease of operation.

    Humidity controller is the perfect way to ensure your plants grow throughout the year even during summers, without wilting because of low humidity levels.
