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. Get yours today and take the guesswork out of indoor growing!

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.

    Très bonne qualité
    Ce thermomètre est vraiment bien pensé, il est de bonne facture. En plastique certes mais ne parait pas cheap. Je m'en sers pour prendre la température ambiante et celle à l'intérieur de mon frigo avec la sonde en + Ben c'est excellent, avec les aimant à l'arrière, on dirait que c'est fait pour ça :) Point positif - Très bon produit Point négatif - Je dois changer de frigo

    Let not Fortune catch thee unawares
    As if borne upon the fleetest steed, it arriv’d — whole and unmarred, a thing of quiet perfection. Purchase it, lest Fortune, in her fickle dance, lead thee to ruin. It commandeth water and heat as is meet, as thou wouldst have it. For this, my thanks.

    Pratique
    Thermomère/hydromètre pratique pour ajuster la température des kits au besoin ... mais j'ai des doutes sur la fiabilité car dès fois cela reste à 100% d'humidité, même quand l'embout est hors du sac, et ça n'est clairement pas le taux d'humidité chez moi.
