Finally! You have achieved the goal of creating a fully colonized fungal biomass, capable of fruiting mushrooms. Your spawn run is complete, and now you only have to wait a few days to a few weeks before mushrooms will appear. Complete colonization is similar to the “resting” phase (stage seven) in that there is a meta- bolic shift and preparation. During this time the fungus concentrates on feeding rather than spreading; it is recharging its battery, so to speak, to give it enough en- ergy to fruit as many mushrooms as possible.
You should continue to carefully examine your growing medium for competitor molds or fungi, insects, and other unwanted contaminants, which can quickly mag- nify in numbers
