What's the temp at? Are they in the dark? Are they even sprouting from the seed? from the soil? do you have a water softner? Are they staying evenly moist? Are they soggy and suficating? How long have they been germinating for? Where did you get them from?

FYI we don't know what you know. You need to take the time and tell us every small detail. The more info you give the more likely we are to help. Sometimes we don't want to take someone all the way back to school if they can't even give us the information we need.
