By the next round of sprouting keep an extra eye on the sprouts so you are assured that all mould spores are gone.
MORE HAIRS ON THIRSTY SPROUTS
Back to the root hairs ... You will notice that your sprouts develop more root
hairs if they do not get quite enough moisture.
This is because the root hairs are intended to absorb moisture for the tiny plants. If you do not keep the seedlings moist enough, then they will grow extra hairs to get extra benefit from the small amount of water you do give them.
Conclution: Rinse your sprouts a little more often.
THEY CAN BE EATEN
Roots with root hairs can be eaten. You can cut the roots off, but is it not just a waste of good sprout?
Because the whole sprout contains vitamins, minerals, fibre
antioxidants, enzymes, amino acids even the roots.
