latedsubstrate.An 8-ft. longcolumn, l2inches
in diameter, tightly packed can weigh 120-150
lbs. depending upon moisture content, density
(determined largely by particle or"chop" size),
and spawn rate.
After the top folds of the column have been
secured, the column should be inverted, upside
down.The loosely packed substrate that was in
the top 2 feet of the column is now at the bottom and the dense substrate at the bottom of the
column is now switched to the top. This, in effect, packs the column tightly. If the straw is not
tightly pressed against the plastic, causing substantial cavities, mushrooms form behind the

plastic and develop abnormally. In contrast,
tight fills cause the substrate and plastic to be
forcibly in contact with one another. When an
arrowhead puncture is made, the plastic bursts.
The mycelium is exposed to the growing room's

oxygen rich, humidified atmosphere. Given
proper lighting and temperature conditions, a
population of primordia form specific to each
puncture site. Growers using this technique
develop a particular fondness for strains which

are site-specific to the punctures in their response to standard initiation strategies.
Once the column is removed from the inoculation station, two people carry or trolley it to
the growing room, where it is hung and allowed
to incubate. Overhead trolley systems similar

to those employed in slaughter houses, cold
storage rooms, even clothes dry-cleaner companies can be adapted for this purpose. If the
columns are carried, care must be taken so that
the columns do not sag in the middle, lest they
break. Modified hand-trucks fitted with a slant
board are helpful in this regard.

The columns are hung to approximately 4
inches above the floor. After hanging, they noticeably stretch within a few seconds to become

substantially floor supported. Columns (10

inches in diameter and greater) suspended in the
air after inoculation will probably fall before the
cropping cycle is completed.

Directly after the columns have settled to
the floor, within 1 hour, numerous holes must

be punched for aeration. If holes are not
punched until the next day, substantial loss of
spawn viability occurs, and a bacterial bloom
ensues in the stagnant, air-deprived column.
However, if the column is suspended and holes
are punched too soon, the punctures elongate
and the column soon is in danger of splitting
apart. For an 8 ft. high column, 12 inches in diameter, at least 200 and no more than 400 1/8

in. holes should be punched for maximum
yield. Stainless steel, four bladed arrowheads,
mounted on a board are recommended for this
