I soak for 12 hours and plant in pre-soaked soil. When they pop in the soil, water the outside of the pot thoroughly...and mist the leaves to keep them humming...their roots will reach for the edges of the pot and then head down.My entire method, since you asked
I soak in water inside for 15 hours then place in a papertowel and keep it moist until the taproot gets about an inch or two. Then I plant it in soil (solo cup) about 1/2-1" deep and let it grow inside under a 40W LED until it is time to put it outside.
