Gonna leave you with some bullet statements, I'm busy as hell.
1. Lights need to be almost touching the plants AS THEY POP THE SOIL. Have good air movement. I don't like CFL's. Why would anyone use a light that is turned on itself? 4' shop lights with cool whites is fine, HO and VHO are better but you need some space with them. Suspend the shop hood on a chain so that the smallest plants are positioned at one end, the tallest at the other. Adjust chain accordingly. Light dog chain work great. This allows you to have about the same amount of space between the leaves and the tube. When the leaves grow past the footprint of the reflector, it's time to move into a HID.
2. When you water, do so thoroughly. Untreated tap water is fine, don't stay at the noise level, there are more important issues than pH and water quality to worry about when you grow in soil. When you upcan, score the peat with a razor blade and make sure no peat material is above ground level as it will wick away moisture. Bury as deep as you can.
3. There is some kind of stress working, see my sig thread and my Tweak thread for more info.
4. Boxes/cabinets suck. The great outdoors is not a box, it does not confine.
Good luck,
