400w Metal Halide for first month of flowering?

[smokenss]

that might b the go then use flouros untill the plants start to flower then the hps or both together. that might help keep time in the flower room down to 6-7 weeks insted of 8-9 witch would means another crop or 2 a year:smokin:

Would the blue spectrum make it more leafy? Would i be better to make it full HPS after 4-5 weeks? It makes sense... blue promotes leaf and stem growth....

What about a 2' X 4' X 8' area(closet) with a 400w hps and a 250w MH for flowering? Moving plants around every 3 or 4 days for an even light distribution, provided the temps remain within an acceptable range? I ask this because I have 3 lights with 2 closets - 400w hps, 250w mh and enough cfl's to light-up a small village!!

This is good if you have some badass ventilation or you can keep the door open all day. A 400w and a 250w would give you about 81 watts per Sq.Ft. Which 81 watts per square foot of full spectrum lighing would be badass... but difficult to keep at a consistent temp. I would just use the HPS (400/8=50 watts per sq) with a few cool blue CFLs.

Its a rail... with a motor that moves the light very slowly so you light covers a larger area. And since the light moves you can keep it much lower to the canopy without burning it. And they cost around 50-200 dollars depending on where you look and what kind.
