I will also havea normal 400 watt mh going with this one. any good?

I have heard good things about a blue mh like this so i am to curios to see if anyone responds that is using it. I have heard nothing but good things though. I should be buying one soon. And as an addition i think would be the best route.

It will work just fine, I use a halide lamp alongside an HPS for bloom lately.

I decided to go with a mh red grow light to try to mimice the hps light. I have three mhs and dont really wanna buy hps. Any good?
