A thermometer and a hygrometer are essential tools for ensuring ideal conditions for the home mushroom grower. Having both of these tools combined into one easy-to-use unit halves the fuss and doubles the efficiency. The Psilocybin Mushroom Bible recommends a constant humidity of 90% and a temperature range of 21–27°C. Having a single unit that monitors both parameters makes the perfect fungus environment easy to maintain.

This accurate unit is ideal for all mushroom growing systems. Grow kits, bags, and any size container can be checked with the push of a button. The long cables and easy-to-attach probes mean never having to disturb your grow. The readout can be mounted outside the grow space to ensure a stable environment at all times. The battery is included, so the unit is ready to go upon delivery. Shroom-on brothers and sisters!


The complete unit is a readout panel with two suction cup mountable probes, each connected by long cables.

  • Affix each probe in the centre of the grow bag or from the lid of the container. Picture where the mature height of the shrooms will be and extend the cables so the probes hang right there. Too high or too low can give inaccurate readings.
  • Place the readout display wherever you want as the long cables allow for convenient positioning.
  • Optimal humidity: 90%
  • Optimal temps: 21–27°C

    Pas mal pour le prix
    Thermomètre au top, mais la sonde de l' hygromètre ne doit pas rester constamment dans le sac de culture je pense, afin de la préserver plus longtemps


    Igrometro difettoso
    L'Igrometro segna sempre 99% di umidità, sia all'interno (IN) che all'esterno (OUT)


    Très moyen
    Le 1er commandé avait un problème avec le capteur d’humidité. Zamnesia m’en renvois un sans discuter mais il a le même problème


    Great if you need it
    Especially for first timers, or if you're unsure about your conditions. This will show you moisture level and temperature, so you know what optimal conditions are like. Remember fresh air is also as important as moisture.


    I love this little thing
    Just as advertised...


    Works like magic and cheap


    As long as you are careful not to put water directly on the sensor, it wrks pretty well. I've been using it for a month and it still does the job.


    zeigt immer 99,9% luftfeuchtigkeit an
    bin mir hier nicht sicher ob wir hier von top qualität reden aber preis leistung passt und es ist halt eine ca skala das man einen richt wert hatt für die temp feuchtigkeit aber würd echt 5-20€ mehr zahlen und ein richtiges holen sowas kann man ja immer brauchen


    excelente producto, de muy buena calidad y mucho mas barato o igual que el resto del mercado !
