Ummm, I am a bit new to the horticulture scene, but wouldn't it be a bit early to repot. With the pictures posted, if he repots up to coytolyns now there won't be much above the dirt, coupled with the potential for transplant stress, I think it may be a little pre-mature to transplant..... Perhaps after 2-3 sets of leaves??? Check out the Grow FAQS there is a guide to transplanting...that is basically how I do it , minus the rooting hormones.

I agree with the lighting issue....I would get at least 1 good, cool, CFL (43 watt) about 1-2 inches above your girl (positive thinking)....I use a cheap spot light fixture for seedlings. (see picture)

Start thinking about what you want to use for lighting once she gets bigger...floros work good for beginers and can produce decent results.

Good luck.
