I am just watering with tap-water, though I have several old water bottles that i have filled and keep in the room. I did that so the temp would be the same as the room.

I do not think I am over-watering, after I planted the seeds I saturated the soil until it ran out the bottom. Then I have done this once more in a weeks time. I don't think it was dry the last time I watered, but the top of the soil was dry and I figured keeping it all equally saturated would be ok. I am defiantly not flooding them.
