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

    Fonctionne bien
    Le produit fonctionne très bien l'option qui permet de vérifier la température minimale et maximale atteinte est très pratique


    Simple et efficace
    Très pratique pour contrôler l'environnement


    Good and at a fair price
    I like it very much. It measures separately temperature and humidity inside the kit and outside the kit (room) and records minimal and maximum registered temperature. Alternating between all these information on the display can be a little confusing for some people at first but easy to get used to after a while. It is important to keep in mind that the humidity probe sensor is inside a little cage, and in a high humidity environment (like a grow kit) this cage may condense a little bit of water, and that may result in a faulty reading. But that is an issue with most hygrometers I guess.


    Cheap, does the job, quite precise. Perfect for mushroom growing.


    Works like a charm in mushroom cultivation


    Top qualité d'un produit incontournable....
    Pour un prix très concurrentiel, vous pouvez surveiller le séchage et l'affinage de vos plans tant chéris et rectifier le tir afin d'éviter le pire ... Pour moi, c'est TOP Thx Zamnesia ;-)


    Ok pour la température
    Très pratique pour suivre la température. En revanche pour l'humidité je ne suis pas convaincu. Il lui arrive de se bloquer à 99% sans doute quand il y a de la condensation et il faut sortir la sonde et attendre qu'elle sèche avant de pouvoir réutiliser. Donc la sonde d'hygrométrie ne me semble pas adaptée à une ambiance ou l'humidité peut monter très haut.


    Semplice, preciso e funzionale, praticamente fa ciò che serve. prezzo giusto


    Worth it for the price
    Considering the price it does it's job but don't expect 100% accuracy, especially the hygrometer. Good for having a general notion about your cultures when you're beginning your cultivation journey.


    perfect for my wish
    Its working great.
