Use a mix of potting soil and perlite 50/50% water it before u put the seed with straight PH'd water, no nutes, dig a 1/4 inch hole and put the seed in, cover it lightly with the medium and Wait 3 days. 100% warrantied. I think same principle applies for hydro methods only changing watering schedules, like with RW it'd be longer than rapid rooters and so... IMO Paper Towel is the worst out of all germinating methods so you'd want to stay away from that.
