IMHO it is worth the little extra electric for the improved spectrum.
Besides old fashioned iron core ballasts are reliable as a.......rock. (and as advanced)
Hey oldmac,

I didn't really understand what you were saying here. Could you explain this post to me in a little bit more detail. Sorry for the electrical incompetence, not a big electricity guy (something I want to learn MUCH more about).

What did you mean by 150W per 1000W. Are you simply saying that you think it's worth the use of a tad bit more electricity required by a magnetic ballast to pump out the large spectrum coverage of a CMH bulb?
SauceeMcGee Reviewed by SauceeMcGee on . MH vs. HPS Ok...a good friend of mine and I started growing at the same time. We both do a good amount of research and he found some info on these two lamp types that I want to run past everyone: MH lamps: are used primarily for veg growth right? Well what we read was that MH lamps actually dictate how bulky the plant gets, but most importantly...also dictates the amount of trics buds will develop, the overall potency of the bud from what I understand. Now HPS lamps: These lamps seemed to be Rating: 5
