Horray!! Now you just watch em grow

The 2x50w fluorescents should be plenty - I wouldn't bother with the halogens, they generate a bunch of heat and the light isn't a favourable spectrum (I am right here people yes?)
Remember to keep the lights as close to the plants as possible without damaging them with the heat. The intensity decreases exponentially with distance.
Keep them damp and warm and watch them grow - when the leaves stop coming out in pairs it's no longer a seedling and you can sex the plant and decide what to do next.
