Those seedlings shouldn't be in clear plastic cups. Roots don't like light. You don't want to disturb the plants, so wrap the cups with something lightproof. Cut four drain holes in the sides of the cup right at the bottom. Your plant is too deep in the cup. Since you can't move the plant, trim the top of the cup down some. Your plant needs to breath.

Water the plant when the top inch of soil is dry, not twice per day. Get some cfl lights and put them on an 18/6 light cyle under the cfl's.

Essentially, other than putting the seeds in soil, you have done everything wrong. Take some time to read the Grow FAQs.
