Doog is right, you don't need a lot of light, check out my seeds in my thread (winter 2013/2014 Garden). Im using 2 T5's 2000 lumen each 6500k spectrum

yours look fine, this stuff takes time, don't expect it to happen so fast, also the strain has a lot to do with it also

a little humidity dome will help regulate the temperature, one main key to starting seeds it to keep a constant environment.
since your using solo cups. find a clear solo cup Ive seen them around stores. take one and mount it upside down on top of the ones you have, walla you have a cheap Moisture Dome.
