easily be overwatered, thereby stifling mycelial growth; and secondly, the mycelium
breaks through the surface at different times, resulting in irregular pinhead formation.
When applying the casing to large areas, "depth rings" can be an effective means to insure evenness. These rings are fabricated out of flat metal or six inch PVC pipe, cut to
any depth. They are placed on the substrate and covered with the casing, which is then
leveled using the rings as a guide. Once the casing is level and even, the rings are removed.

Although the casing layer must be even, the surface of the casing should remain
rough and porous, with small "mountains and valleys". The surface structure is a key to
opfimum pinhead formation and will be discussed in more detail in the next chapter.

Casing Colonization
Environmental conditions after casing should be the same as during spawn running. Substrate
temperatures are maintained within the optimum range for mycelial growth; relative humidity is
90-100%; and fresh air is kept to a minimum. (Fresh air should only be introduced to offset overheating). The build-up of CO2 in the room is beneficial to mycelial growth and is controlled by an
airtight room and tightly sealed fresh air damper. If the entrance of fresh air cannot be controlled, a
