Sterilized sawdust & bran mix ready for inoculation. Sawdust is a blend of locally-sourced, coarse and fine-wood pieces, supplemented with 15-20% organic bran. It has been heat-sterilized for 8 hours and sealed in a filter patch bag. 

This is substrate used for final stage mushroom production - also known as "bulk substrate".

This blend gives superior consistency while maintaining density and moisture retention for rapid colonization and high yields. It is suitable for all wood-loving species of mushrooms. Is not recommended for dung-loving species such as agaricus (button/ portobello).

We recommend inoculating this substrate with grain spawn -- it is generally not recommended to inoculate sawdust with liquid culture, agar or spore syringes. A grain spawn rate of 10-20% is generally recommended, although spawning rates of up to 50% can be done to reduce risk of contamination and speed up colonization time
