My seeds arent germinating

[Juggalo smoker]

I started germinating some Shiva seeds four days ago with a plate, wet paper towel and a bowl over top. I dont know if I'm just being impacient but why wont they sprout. This is my first germination, I usually plant. Any tips
thanks

You have provided water, and darkness ut what about warmth? Remeber don't check up on them every friggan hour give it a whole day. I germinated 2 seeds in 28 hrs on top of my computer motem.
