Lol, no one here uses MH in the flowering stage? That's awkward since MH vs HPS is still debated, let alone HPS vs CFL. Finish one debate before moving onto another. To be brutally honest, anyone who is paying for CFL's and going for a decent grow op should invest in an LED. LED's use less energy, produce less heat, and are good for both vegetative growth AND flowering. No need to move your lights around every day either, since they can be set 6-12 inch's over your canopy, and moved once a week. The downside to LED's is price, and even that is coming down. LED's pay for themselves in a couple months of growing. While none of this is from personal experience yet, I am going to be setting up my LED with my MH.
People neglect the blue spectrum in flowering, hps does a ton at promoting flowering but more blue would increase growth. Increased growth + Flowering Promotion = CMH. People who are worried about their plants height are slowing down the growth of the plant by using an HPS, for more buds in a smaller area. While MH produces bigger plants, and done properly would yield more in the same time period with a notably more resinous appearance. All of this comes from reading, flame all you want. I did my research, flaming me is not going to make me feel bad. I know from Expert growers what works best, and what does not. Not to down anyone here, I'm sure a handful of people here have that level of experience. Most of them wouldn't bring themselves down to the level of debating CFL vs HPS. If you are so set in your ways that all you can do is rely on the way of growing, no matter what anyone tells you. Then you are going to grow that way no matter what, so why bother debating the subject?
