Why are there mushrooms only growing from the side of the casing?
This usually happens for 2 reasons: 1.
This usually happens for 2 reasons:
1. Your terrarium and the casing is likely too dry. That's why the
pinhead formation only takes place between the casing container wall and the
substrate where humidity is higher.
Rise the humidity to near 100%RH during the pinning stage and lower it to around
90%RH once the pins have reached 3 -4 mm. Also keep the casing moist (NOT wet)
during the whole cycle by periodically misting it when it appears too dry.
2. You are using a translucent casing container. This way pins form where the
light can get to the substrate.
Use an opaque container to prevent this from happening.
