In looking at the light spectrum of the bulbs, interestingly the 400 mh put out better numbers in the curve of the blue spectrum, than a 1000 mh, same brand. The kid explained that was the spectrum I wanted for the least $$ per kwh.

My concern is will it hurt the other plants under the hps (in the same grow area) to have both lights going at the same time, just the finishers closer to the 400? Crap I have re-written the question 6 times and not sure yet if I asked what I mean. Don't feel so well today. Need to get stoned so I can think straight

You see I was thinking on adding more lumens to the flower room anyhow. If the addition of both spectrums of light helps and doesn't hurt them the question about what to do answers itself.

On the other hand, if I have to put them back in the veg room, that screws up so much stuff I just as well have another room and that is not worth it to me.
