long time reader, first time grower/poster. 4 weeks into veg, had each under 23 watt cfl's, then just built a hood containing 6 sockets with y splitters. the entire back row of lights are the 23w warm bulb. the front row have 4 13 watt blue spectrum light and also 2 23 watt bright white. all purchased from the depot. i think there awfully small for 4 weeks but this is my first time so please comment so i can have a sucessful harvest.
