lighting question.

im in a 9 ft long 4 ft wide area, would 2 600 w and one 400 watt in the middle be enough to grow the entire area along with some 4 ft tube flourescents along the walls horizontally around half way up the final height of my plants?

Sounds fine, as long as youre not growing really tall plants. Keep em under 3 feet or so and the 600w's should be ok.
Do you already have that 400 though? I think 3 600s would be better.

I dont think you'll need the fluoros if you have good reflective material on the walls.

yes i already have the 400 w and im doing an sog and planning on my plants final height to be 3 ft tall

Very good for plants, the brightness is enough!Plant growth will be very good!

ya that would be good for like 30 plants

well its 36 sq foot and im gonna place each plant in a 1 x 1 sq ft space but i guess i could cut back from 36 to 30, that is good, also with this much light and good nutes / good high yeild strains will i be able to harvest an oz from each plant if they veg till 14 - 18 inches and are ready for harvest at 3 ft? i know that is a hard question to answer but if anyone could try that would be great.

Can someone tell me how much distance should be between my MH and my 12 day old plants. Have them on 75% power now under 400 watt. They look good but the two autos I have are so small. One looks like a mutant. Only 2 leaves and they look screwed up. Auto Bomb. Have 5 plants in a 4 x 2 foot space.

I would keep the light 18in for the first 2 weeks then lower it to 16inchs for the next 2 weeks 16inchs after that.
Thats on 75percent whitch is 300 watts thats perfect for seedlings once they get around 8inchs tall ide put the light
to the 100 percent setting

Thanks for the reply. Don't know why I typed 400 watt as it is 600 watt but I can adjust from your answer.
