their substrate if working on a mixing line, or
nearly all commercial mixes have wetting agents
incorporated. In North America, we initially water
our pots to full saturation (based on long standing
advice) before putting them into the cooler. This
is somewhat different from Holland, where one
really does not see spring bulb forcers fully saturating
the media at planting time. One idea put
forth is that coolers in Holland perhaps are designed
differently, with coils and mechanical components
that pull less water from the product in
the room. In this way, pots dry out less during the
long cold period.
