Grow1 Indoor & Outdoor Temperature And Humidity Hygrometer w/ Probe

The hygrometer meets the need of all kinds of greenhouses and grow rooms. The meter's wired probe displays vital information like temperature humidity, weather, time, date, forecast ads, max/min temperature, etc. With the alarm and the snooze function, you know when to stop and reschedule the timer. Measuring the amount of water vapor in the air is crucial as it decides how the plants' health will be affected. The hygrometer actively measures the amount of water vapor and humidity present in the air. Too little or excessive moisture may completely mess up the balance in air and damage plant growth. The hygrometer requires 2-AG10 batteries, which are highly efficient. You do not get batteries along with a hygrometer, and so you have to purchase them separately.
