The benefits of starting in a wet towels isn't worth the risk of ripping the tap root when you peel apart the wet paper towels.
Starting them is the tride and true way, and the way mother nature has used for millions of years.
Push you index finger down in the growing medium up to the first knuckle.
Drop the seed in. Cover it gently, do not pack the soil down leave it loose.
Then mist the area with tap water. Keep it moist but not wet. You don't want to drown the baby.
Don't allow it to dry up. This will kill the baby as well.
Just get a dollar mister bottle from any local store.
Mist 5 or 6 pumps in a 4 inch circle surrounding the seed, as many times per day as needed. Whether it be 3 4 or 5 times a day.
Goodluck it's not hard man. Don't sweat the small stuff. Don't over think it. Most of the time when plants fail its because we over complicated the situation. This is a weed that grows in the wild and has for years and years. If conditions are ideal, and it has moisture in the area it will grow.
