if your lights are mh or hps i would say yes. even flauros could pull it offnot much info added.. maybe why you havent gotten more responses....
how tall are you going to want them b4 they go into flower room: 6 weeks old What strain? What size containers, and what type of 400W light HSP, MH, CFL, Floros, or heaven forbid Halogen. More info would help as you might get a slightly dif answer for each setup/lightsystem
Yea what kine lights are you using if there HPS you should have way more plants but then I would doubt that they are HPS you electricity bill would be outragious for just six plants.
Actually a 400 watt hps illuminates a 3 x 3 area....600 watt - 4 x 4 .... 1000 watt - 5 by 5a 400 watt hps delives enough light to efficiently light a 4'x4' area so if oyu overlapped the light beams to sort of form an M then you should be efficiently covering about 6'x4' area and you could fill that supposed area with plants
If your plants to flower would be medium in size and indica pure or indica dominan, I say most definately especially if your walls can reflect light i.e. flat white paint, mylar, panda film, or foylon. My setup is this fluoros and cfl's for clones/seeds, a 400 W MH for vegetation and sustaining mothers, and a flower area with 2 600 W HPS that flowers 6 medium to large size plants.ok basicly have a room seperated 1room is for flowering and has 3 400watt lights over 6plants.... and now we are going to put 6 new cuttings in.was wondering if say 2 400watt lights would be enough light for 6 plants until they are 6week old and ready to flower.
nah a 250 covers 3 squar feet 400 covers 4, 600 covers 4, and 1000 covers 6 square feet, i would like to know were you got your info from? I got mine from http://www.intl-light.com/handbook.htmlActually a 400 watt hps illuminates a 3 x 3 area....600 watt - 4 x 4 .... 1000 watt - 5 by 5

It all depends on your reflector, but for the most part you are correct. Also, I fully flower 15 plants under 1000watts, and they get big. I would say that with 3 400 watt lights, I would be growing atleast 18 plants. That's just me, so having 6 under 3 400watt lights, seems like they should be very happy and produce a shit load.
