Glass jars for making mushroom spawn, liquid culture or fruiting cakes.
The factory lids are 1 piece - as pictured, sitting on-top of the smaller jar. If you want the 2 piece band and separate lid you will need to add that separately.
The smaller size jar is your typical wide-mouth jar used in BRF (Brown Rice Flour) cake style growing methods. The inner sides of this jar (320ml size) are smooth and do not taper inwards, making it easy for the mushroom block to slide out in one piece.
Jars are autoclavable and are also suitable for canning/ preserving.
You will need to purchase >> paper filter discs here and the >> self-healing injection ports here to make the air-port lids (lid shown in picture 1).
Alternatively we now also offer >> ready made AirPort Lids
