What conditions and equipment does Cordyceps Militaris need to grow?

Cordyceps Militaris is grown in jars or containers on a sterilised substrate, often a cooked grain like rice with added nutrients, sometimes with a silkworm or protein supplement, under near laboratory conditions. You need full sterilisation of the substrate and jars, a clean inoculation done under a laminar flow hood or a very clean still air box to avoid contamination, and then a controlled grow room. The fungus first colonises in the dark, then needs cool temperatures broadly around 18 to 22 degrees C, controlled light to trigger the orange fruiting bodies, regulated humidity and some fresh air, over a long cycle of several weeks. The orange stromata are then harvested and usually dried. The strict sterile technique and climate control are why it is closer to lab work than ordinary mushroom farming, and why contamination defeats most beginners. Get proper training and a verified strain from DMR Solan or a research institute before investing in equipment.
