I soak my seeds for 24 to 48 hours in hot tap water with 2 or 3 sprays of hydrogen peroxide added to the water.
Most seeds sprout in 24 hours or less but some take longer. I never soak for more than 48 hours, even if they haven't germinated yet.
I then sow them in a solo cup with a well-draining potting mix, set them on a heat mat, & cover them loosely with a plastic ziplock until the plant emerges from the soil.
As soon as the plant emerges from the soil, I remove the plastic.
You can get hydrogen peroxide in a spray bottle at Walgreens. I refill my spray bottle.
