I don't soak at all, I find that a moist paper towel works just fine with close to 100% success rate. Back when I started out and at this time of year I ran heat in my house, put the moist paper towl & seeds in a ziplock, wrapped a bath towel around it, and then tossed it halfway over a floor heat duct. The moisture & heat is ideal for germination.
Now days I take things much more seriously, so I just paid the simple $30 for a germination mat, which simply plugs right into a socket and gives you a pouch to put your paper towel & seeds into and maintains the ideal temp for germination. I found mine in the home depot garden section.
Def take those out of the shot glass tho, if you do soak, 24 hours or less is plenty
