Filter Bag


The bag has several microporous filters incorporated into it so gas can pass in and out but moisture stays in and contaminants are kept out. This is important as during mycelium growth phase, a lot of CO2 is given off and needs venting, but the medium must not dry out. In short, the bag creates and maintains the perfect environment for shroom growth. These bags are autoclavable.

    Replaces the not optimal supra grow bags with these ones and they are perfect! No leaking as with other bags and the air filters in the top provide enough oxygen. I recommend

    Good Quality

    le top du sac filtrant


    Super Qualität Vielen Dank


    Sac multi-fonctions
    Peut servir pour la culture de champignons (azurescens, cubensis, tampanensis..), la culture de petites épiphytes (orchidées, broméliacées..) et aussi très pratique pour les semis ou bouture à l'étouffée.


    Does what it's supposed to.


    Indispensable pour la culture de champignons...
    Indispensable pour la culture de champignons et de truffes... Parfait pour garder l'humidité tout en filtrant l'air entre l'intérieur et extérieur du sac.


    Meglio del sacchetto originale con cui arriva il kit!
    Qui l'aria viene filtrata, non ci sono i buchi, ma ha dei filtri microporosi. è inoltre perfettamente adatto per il grow kit da 1200ml.


    Perfect for growing shrooms
    Nice quality. Better than the ones you get when buying grokits

Ich würde gerne die Maße des Beutels wissen, wenn das möglich ist. (Länge, Breite, Höhe in aufgestellter Form)


Our Filter Bags measure approximately 49 cm x 20 cm. Perfect for our 1200 ml Grow Kits ;)!
