more lights or not

Hi all am currently growing 7 super skunk day 16 flower that are under a 600w light i have another 600w light availible would it make much of a differance to the final size of my crop if i added it to the room .

couldnt hurt i got 2 400 watters on 15 plants and wish i had one more 400 watter

yeah man get it on.........

I use all the available light i can get my hands on i dont care what it is i got extra cfls and tubes running too if i had a 600 availabe i would have done had that sucker fired up
get on in man but keep a eye on your temps

thanx for the replys guys putting it in tommorow.
