I'm not familiar with CMH as I've never tried them. I can't make an honest comparison. But I have used MH / HPS & I can make an honest comparison there & the Mars Hydro TSW 2000 (300 Watt) will do just as good as a 600 Watt HPS.
The TSW 3000 (450 Watts) is damned near equal to a 1000 watt HPS. No big difference in yield between them. The Big Difference is in Heat & Electric between the 2 types of lights. I'm not sure, but maybe this is because of the Hood Types & the Light Spread. But either way, from my own personal experience I can't say either one produces Bigger, Better yields. Pretty damned close to equal both ways.
One just costs more to start out with & is cheaper in power. The other cheaper to purchase but costs more in power.
I only have to pay extra once during the initial purchase of an LED. The HPS guy has to pay extra every grow in electrical costs not to mention new bulbs quite often.
So this is why I chose LED over MH / HPS. Last I'll say on the subject.
Anyway, those are some beauties Delta ! Keep up the great work. I may try a CMH since they are dirt cheap. Seems like those lights are all over Craigslist & Offer Up for about $100. I just don't see why people are selling them off if they are that good. Way more MH / HPS / CMH lights for sale then LED's .... Hmmmm. When I see a whole bunch of the same kind of lights up for sale I think "Thing of the past". Kind of like Blurple LED's.
