Reminds me a bit of my first.......

Is that tin foil? if so ditch it for mylar or my first I used white poster board I had laying around.

I hope you at least have a cfl in that lamp, if not do so, incandescent light is no good.

Lastly get the light closer, she is stretching, search the growing section and you will find most all your questions answered.

Good luck to ya!
