Right now I have a 175w MH in my veg. room. and a 400w HPS in my flowering rm.
What would be better for vegging, 175w MH or a 150 HPS?

you want about 2000-3000 lumens a sq ft in veg.. and 5000 lumens a sq ft in flower... SO take the amount of lumens that 175 watt MH produces and divide by 12. Im guessing it puts out about 14,000 lumens ( you can verify this online for your specific bulb) .. divided by 12sq ft = 1,166 lumens a sq ft. I would say that light is good for a 2x2 - 2x3 area max for veg. So once your plants take up more space then that .. add more lighting .. or if you run both the 175 and 150 .. you will have more then enough. The biggest problem you get when there is not enough light in veg is .. slow growth and Stretched plants. Both are not very desirable.. Hope this helps

depends what lights you have..?? A 60/40 mix of light .. 60 percent being hps and 40 percent blue spectrum .. is actually REALLY good for the plants.. but most people go straight hps. whats the setup?
