Filter Jar 280 ml – Mushroom Grow & PF Tek Starter Jar

The Filter Jar 280 ml is a compact and practical cultivation jar designed for sterile mushroom growing and mycology projects. This smaller size is ideal for beginners, testing new strains and small-scale cultivation, offering excellent control and efficiency.

The integrated breathable filter allows proper gas exchange while maintaining a sterile environment. This supports healthy mycelium growth and helps reduce contamination risks during incubation.

Perfect for Beginners and Experimental Growing

The 280 ml size is especially suitable for:

• PF Tek starter projects

• BRF cakes and small batches

• Liquid culture

• Strain testing and experiments

• Small-scale and controlled cultivation

Its compact design allows growers to work with multiple jars, making it easier to compare results and refine growing techniques.

Optimal Gas Exchange and Sterility

The built-in filter ensures proper airflow while blocking bacteria and mold. This creates stable and controlled incubation conditions, which are essential for strong colonisation and consistent results.

This makes the jar suitable for both new and experienced mushroom growers.

Durable and Reusable Design

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

Lightweight and Easy to Handle

The transparent design allows easy monitoring of mycelium growth. The wide opening makes filling, mixing and cleaning simple and convenient.
