Hygrometer / Thermometer

ENSURE THE BEST CONDITIONS FOR YOUR GROW

Keeping close tabs on the environment of your indoor garden is central to growing healthy plants or fungi. Whether you're awaiting a bountiful harvest of cannabis or psilocybin mushrooms, trying your hand at growing your own fruits or vegetables, or simply looking to take better care of your houseplants, a hygrometer-thermometer should be high up on your list of must-have grow tools.

Temperature and humidity are key factors to monitor when growing any plant, and even the hardiest houseplant or cannabis strain can be affected by sudden changes in humidity or temperature. Houseplants, for example, generally grow best at daytime temperatures of 20–25°C (70–80°F) and 60–70% humidity, though some tropical plants prefer notably warmer, more humid conditions. Cannabis, on the other hand, loves daytime temperatures of 22–28°C (72–82°F) and humidity levels of anywhere between 40–70%, depending on the strain. Finally, if you've purchased one of our Magic Mushroom Grow Kits, you'll know that Psilocybe mushrooms need very stable conditions, with temperatures of 21–24°C (70–75°F) and 90–95% humidity.

With this inexpensive 2-in-1 tool, getting an overview of the conditions in your home, tent, grow room, or greenhouse couldn't be simpler. With the push of a button, you'll get a crystal-clear reading of the temperature and humidity of your environment so you can go ahead and correct any issues if need be.

How to Use an Indoor Hygrometer-Thermometer

Each unit comes with two mountable probes. To use your hygrometer-thermometer:

1. Connect the probes to the screen display.
2. Fix the probes somewhere in your grow space (under or above the canopy of your plants, for example).
3. Place the screen somewhere where you can easily read it.
4. Press the In/Out button to turn on the unit and, within seconds, get an accurate reading of the temperature and humidity in your grow space.

Note: In larger spaces such as grow rooms, consider taking multiple measurements at multiple places inside the room to catch any differences in conditions. When growing cannabis, you may observe different temps/humidity levels above and below the canopy of your plants, for example.
