But after a length of time, there will be mold, even if pre-soaking the seeds in peroxide and using distilled water and clean hands. I change the paper towel when this happens.
An example of good peroxide effects: Nigella damascena seed instructions say 1/8" deep in darkness, germinates in 10-15 days.
I soaked mine in a mild peroxide solution for a few hours and sowed into moist paper towel in a ziplock. Put it in a black box and left it between my window screen and pane. 4 days later they sprouted!
My balloon flowers are so tiny, really behind schedule too. And my columbines didn't come back! I went to my old apartment and every single one of the ones I planted outdoors came back and are blooming beautifully. *pout*
