Seeds and bulbs
Does soaking seeds and bulbs in water and liquid fertilizer overnight promote better growth?

Some types can be soaked in water. Most bulbs will not want this, however.
I would also not recommend adding fertilizer to the seed water. This will, potentially, burn any seed roots before they emerge. The seed shell (cotelydons) will container any nutrients that a plant needs for the first little bit of its life, before developing photo synthetic leaves.
I would make sure that the specific seed that you are trying to germinate will tolerate being submerged, as some do, and some don't.
