Most
seed types require little more than 1-12 hours of soaking followed by
varying periods of unattended sprouting time (and no rinsing.)
Some seeds have special handling needs. For example:
Alfalfa & Salad Sprouts
Salad-type sprouts such as alfalfa, broccoli, clover, radish, etc.
are usually grown to a more mature leaf stage. Water is useful for more
than just growth - it's a way to keep sprouts from growing into a tight
compacted mass, while simplifying dehulling and rearrangement of sprouts
for uniform greening. (At each rinse, fill sprouter with lukewarm water,
loosen sprout mass with a fork, stir, skim hulls & drain.)
