Let me just tell you how I germinate in soil ... I thoroughly soak the soil using water with microbes and ph balanced... I then plant the seed, put an inverted saucer over the top (to make sure the seed is germinating in the dark) and put the whole thing in a trash bag that is tightly sealed to make sure it stays very VERY humid. I then let it alone for 3 days. I'll open things up on Day 3 to see if a sprout is showing ... if not, it gets wrapped back up again and I'll check it the next day. The longest I've had to wait for a seedling is 4 days... they're usually up in 2-3 days... if I don't have anything by Day 5, I gently dig around to see if I can find the seed - which usually I can't because it's a dud and I pitch it.
Doing it this way, you don't have to worry about how much water to give it ... it's got plenty to work with and adding the microbes at the beginning will help the newly formed roots spread and grow really quickly.
If I were in your shoes with your seeds right now, I'd use a spray bottle so the watering is gentle but I would spray a lot to make sure the water permeates down ... Good luck with your grow!
