dont put them in water that long!!!!!!!, that is called the shot glass method, you place your seeds in luke warm water and they will float, leave in a dark warm place and wait between 12-24 hours, if they havnt sunk already push them down firmly and if they sink to the bottom they are good to go, then you can pop them straight into soil, but what i like to do is when they sink, transfer to paper towl method, keep nice and warm then when there is the tinyest little shoot pop them in soil, keeping the seeds in water too long will drown them, or you can listen to hog budd, he really really knows what he is talking about and he has taught me a few things, whats your set up ?
