Slanted Wall or "A" Frame

Slanted walls are constructed by stacking bags
of inoculated substrate to build sloped faces. An
advantage of the slanted wall is that a higher density of fill can be achieved within a given growing
room space and harvesting is easier. A disadvantage is that mushrooms are limited to forming on
only one plane- the outwardly exposed surface.
In comparison, blocks that are spaced apart give
rise to fruitings on 5 planes: the four sides andthe
top, a response seen especially with Shiitake and

Oyster mushrooms.
Many cultivators find that a wall composed of
individually wrapped blocks limits cross-contamination from infected units. Isolation of the
blocks, or for that matter any fruiting container,

has distinct advantages, both in terms of yield
enhancement and contamination containment.

Bag Culture

In the search for inexpensive, portable, and

disposable containers, plastic bags have
became the logical choice. High temperaturetolerant polypropylene bags are primarily used
for processing wood-based substrates which
require higher temperature treatment than the
cereal straws. Once cooled and inoculated, sterilized substrates are usually filled directly into
heat sensitive polyethylene bags. Mushrooms
fruit from the top or sides.
For the cultivation of most wood decomposers, a biodegradable, heat-tolerant, and

breathable plastic for bag culture is sorely
needed. "Cellophane", a wood cellulose-based
plastic-like material used commonly in the mid
1900's, has some of these features (heat tolerance, gas porosity), but lacks durability. Despite
this shortfall, one of the most appealing aspects
