Hmm, when just popping them into the soil it can take longer than 3 days to show sprouts. Also seeds don't need light, but they need warmth and a humid climate. Try covering the pots with plastic rap to try to keep the seed in a humid climate. Why aren't you just using the papertowel method used by so many on this board? That is the way I do it and have no complaints. Look up germination with the search feature and read up on it, maybe you will get some more tips.
