Struggling with crispy leaf edges? A reliable indoor humidity monitor is the only way to know for sure if your tropical plants are getting the moisture they need. The HTC-1 takes the guesswork out of your daily plant care by showing you exactly what is happening in your room's microclimate.

Most plant problems trace back to environmental stress — usually cold drafts or dry air that you can't feel, but your plants definitely do. This compact unit displays the current temperature, relative humidity, and the time, all at a glance. We even include a fresh AAA battery so you can start tracking your grow space the second you open the box.

• Track highs and lows: Built-in memory records the maximum and minimum temperature and humidity over 24 hours.
• Fast reads: Sensor updates quickly, giving you an accurate picture of your room's conditions.
• Ready to use: Comes complete with a high-quality AAA battery and built-in kickstand.
