Our coco coir, vermiculite & perlite mix, pre mixed, pre-wetted to field capacity and sterilized in unicorn XLS-T bags.

It has been formulated by mycologists to increase the yield of your grow. Over several years, it has been perfected for dung-loving mushroom species and is widely-trusted by mushroom growers.

Use our substrate in filter bags, and outdoor beds. Or, grow mushrooms from the bag or tray in a humidity-controlled grow room or Martha set up.

We recommend a 3 to 1 ration of inoculated grain to bulk substrate.
