When you return in the
morning, the seed will
have swelled, and the
container will be full.
The seed can then be
dumped into the tank as
needed. Pre-germinated
seed will normally come
up in about half the
normal time. It is also
useful when seeding in
cool weather, or hot
weather. Grass seed will
only germinate at
certain temperatures.
By pre-germinating the
seed, it is less necessary
to worry if the ground
will warm up enough, or
cool off enough for the
seed to germinate.
There are other systems
that will provide even
faster germination that
are often used in
applications where fast
germination is critical.
One system involves pre-
germinating seed for 24
hours on the basis of 4
hours in water and 4
hours out of water for
the full 24 hours.
Another system involves
soaking the seed for a
few hours, draining most
of the water, and passing
air through the seed for
24 hours. People using
these systems often feel
they reduce germination
time by 90%.
MULCH
There are two main
varieties of hydro
seeding mulch.
Cellulose fiber mulch
and wood fiber mulch.
There are also mulches
that are a combination
of the two types. Both
types of mulch will give
good results. We
recommend cellulose
mulch in our system.
Cellulose fiber mulch
also known as paper
mulch is easier to use,
requires less material
to do the same job and is
less expensive. Cellulose
mulch works by sealing
the moisture in and
making something like a
thin paper machete
covering over the soil
and sealing in the
moisture. It is
inexpensive and very
easy to use.
Wood fiber mulch has
strands of wood that are
up to 1” long. It works
like miniaturized straw
and requires heavy
applications. Sometimes
in windy conditions the
fibers of mulch will act
like a wick and actually
pull the water from the
soil. Because the seed is
disbursed evenly
through the mat that is
sprayed on and because
the layer of mulch needs
to be much thicker, less
of the seed is in contact
with the soil. Any system
even large mechanically
agitated systems will
have the plugging
problems using wood
mulch.
We do not recommend
wood mulch in our 50, 100
or 150 gallon systems
with the exception of
pelletized mulch which
is 80% paper and 20% wood
fibers. In the 300 gallon
and larger systems a
combination mulch may
be used. When using a
