rookie grower

Hey I got this real ghetto set up right now I'm really hopin it works but I have my doubts.

So my setup is in an attic 3 plastic cups with holes in the bottom inside of a cyclinder trash can with a 55w fluorescent bulb a couple cms away. No iv had light on them about 18. Hrs a day with about 4 hours off for 4 days now but nothing has sprouted. Should I give up and start again? Or could it still possible work.

I find that this works best when you wrap the cups in cling film to build up the humidity within the cups. Seeds like warmth and humidity. Once the seeds break ground I remove the cling film.

If I want to check on my seedlings I'l squeeze the tops of the cups, this causes the soil to break apart or split and I usually see if a root is forming or not.
