Filter Jar 1200 ml – Mushroom Grow & Grain Spawn Jar

The Filter Jar 1200 ml is a high-quality cultivation jar designed for sterile mushroom growing and mycology projects. With its large capacity, this jar is ideal for preparing grain spawn, liquid culture and substrate colonisation.

The integrated filter allows proper gas exchange while maintaining a controlled and sterile environment. This supports strong and healthy mycelium growth while reducing the risk of contamination during incubation.

Ideal for Mushroom Cultivation

This 1200 ml filter jar is suitable for a wide range of applications, including:

• Grain spawn preparation

• Liquid culture storage

• Mycelium expansion

• PF Tek and advanced cultivation

• Laboratory and home growing

The larger volume makes it perfect for growers who want to scale their production or work with larger batches.

Optimal Gas Exchange and Sterile Environment

The built-in filter system allows fresh air exchange while blocking contaminants. Proper airflow is essential for strong colonisation and stable growth conditions.

This helps create a reliable and controlled environment throughout the incubation process.

Durable and Reusable Design

The jar is made from strong, heat-resistant material suitable for sterilisation in pressure cookers or autoclaves when used correctly. It is reusable and easy to clean, making it a cost-effective and sustainable solution for long-term mushroom cultivation.

Practical and Easy to Use

The transparent design allows easy monitoring of colonisation progress. The wide opening ensures convenient filling and cleaning.
