Used extensively by amateurs and professionals world-wide, mason jars are synonymous with the mushroom cultivation industry. Our UK manufactured, Kilner mason jars are suitable for spawn runs, liquid cultures, BRF cakes or even bottle grows.

We offer two of the most popular mason jar sizes, 1 litre & 0.35 litre – These jars are also known as canning jars or preserving jars.

Our larger 1 litre mason jars are often used for grain spawn production for which they are perfect.

Our smaller 0.35 litre jars have a slight taper and smooth inside. Commonly used for making larger sized BRF cakes and to store liquid cultures.

Lids can be easily modified with injection ports, syringe filters or to simply have holes punched to allow for adequate air exchange if using Tyvek as your filter.

    these smaller jars are bigger than normal jam jars and fit snugly inside my pressure cooker. Used for making BRF cakes as advertised. Good quality and genuine jars.
