Yes straight to soil is good, sometimes I plant straight to soil as well. I will admit I have had seeds that have not germed still this way, but thats me, paper-towel method the same outcome. I also do it the way I did with these beans drop them in a cup of water for a few hours or over night than straight into the medium. I say do what works for you. Like the old saying goes "If it ain't broke, don't fix it , just relax and let it float...." "AFN smoke out" I will say this I only had 2 beans not germ past 3 years.
