Filter Bag

(269)

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.

What do the filters actually do?

They let gas pass in and out while holding moisture in and keeping mould spores out. During colonisation that is vital, since mycelium releases a lot of CO2 that has to escape.

This is a workhorse bag, plain and dependable. See the rest of our grow supplies.

    Just the best option for growing kits
    This kind of bag is just the best option. I don't get why it is not provided by default with the growing kits, but it is way more efficient and safer than the ''micro-perforated'' bags.

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