Hi Purp,
The guys posting right above me both make good points. If you germed your seeds, you would normally see the sprout breaking the surface in about 24 hours or less unless you planted it too deep or compacted the soil too much when you were filling in around your germed seed. Assuming you did none of the above, then you might just have slow starting seeds... I hope. As for the lights, hell you could leave them off until the sprout shows as long as you keep the temps up around 80F or even warmer. When it comes to sprouting seeds, heat and moisture are your best friends. Good luck on your grow!
