The art of sprouting

[virgogirl]

I have been successful at sprouting alfalfa and mug bean seeds for delicious salad toppings. Recently, I picked up some organic sunflower seeds in GDL and have been trying to sprout them. They are bigger seeds and they are rotting in the jar. They smell like rotten fish. Obviously a failed batch.

Any feedback would be appreciated on how to sprout sunflower seeds successfully.
