I have MH lamps and I use them throughout the whole veg and flower phase. I'm thinking of switching to HPS for flowering. Is it really worth the switch, and will my yields be much greater?

HeHe, the age old question that has sparked MANY debates here.

In my experience though, I agree with German and Raw. My first grow was with a 400W MH throughout veg and flower and ended up with a good harvest, but pretty airy buds. Genetics is a huge factor, but when I upgraded to a 400W HPS Conversion lamp (for flowering) for my second grow with different genetics the difference was exponential! A much larger harvest per plant and very tight nugs.

i have a 1000w mh that is light adjusted for flowering as well to reduce need for hps cause it produces same spectrums. what do you think about these types of light.
