Planting germinated seeds pics also

I need some help here this is my second attempt to grow marijuana. I first used the plate and paper towel mix to germinate my seeds. I then planted my seeds root tip down got the soil very moist. I used these clear plastic cups to start the growth and what i did is stacked another cup right on top. This is not the greatest setup but, I feel it will do. I keep the soil moist and covered at all times. I water it 3 times a day with a spray bottle I do not soak it i just give it a couple sprays. Any help is great but just go easy on me here. I did the same thing before with two seeds and they ended up not sprouting and the root tip just seemed to shrivel up.View attachment 277817

Note this is the same setup I had before when the seeds did not sprout. Is there anything else I am missing here.
