We all know, well maybe not, that like you said in your first post (Still, I'm a believer in small HPS lights and combo HPS/CFL grows), dual spectrum works best for the entire grow. If you can't find out the par watts, call any manufacturer and they will tell you after a few forwards-it's not hard, just takes some effort, and not just searching these boards where 90 percent of the answers are: mh for veg, hps for flower-and get the most lumens-not!. I use to grow mh during veg and hps during flower. I use to go by lumens only but could not understand why my grows did not get any better/bigger when I went with the fancy/overpriced high lumen bulbs. Hmmmmm, I wonder why.
Anyhoo, yes I'm a firm believer of the KISS method, and there are plenty of great grows where people just look at lumens. Hell, my ave. yield under a 1000 watt bulb was around 34 oz's, and lumens was all I looked at. First time I went dual (600,400), same strain from clone-38 oz's and the plants were much healthier.
Here's a pretty good site-kind of old: Grow Marijuana FAQ, Cannabis cultivation - marijuana growing tips & photos

Peace and good luck to all.
bushmuncher Reviewed by bushmuncher on . Answers about CFL, HPS, How Much Light... Although I'm still kind of a new poster, I keep seeing a lot of the same comments--many of which are answered an Dr. Khronik's excellent El Cheapo Guide to Lighting. But there are a few things I'd like to add in regard to watts, lumens, cfl, hps, and efficiency and how much light you need. Maybe this should be stickied? Watts have nothing to do with light or growth. Watts measure how much power a light fixture uses to produce light. You can tell how efficient a light bulb is by looking Rating: 5
