ok its just ive read afew posts someone swapped 6000w hps with 2850w cmh and reckoned he was getting more weight and someone else swapped 1800w hps with 1260w cmh and getting a little extra is tbis not the case then

What was said already about every grow room is different so results can be all over the place.
The only thing I can say is cmh shines where canopy is more even.they really don't have much penetration like a high watt hps.so people who grow trees might not like cmh.
You may need more bulbs and some vertical lighting if you plan on growing taller plants or hoods with more direct footprints.
I think cmh are a scroggers dream cause you can add more lights as the same wattage of a bigger hps and get more even coverage.
Heat is about the same unless you air cool.
My 2 open bulb cmh put out a little more heat than my air cooled hps.
There are a lot of variables.
If I had 12 foot ceilings I would probably go to 1200 watt DE gravitas and grow 7 foot plants straight run no scrog to get football cola's in dwc.
Every light and fixture has a place
I don't get why they havnt come out with a dedicated 630 watt cmh bulb and a dedicated square wave ballast.or even a,1200 watt cmh setup with a dedicated cmh ballast would take the industry to the next level.You got it. I put reflective material along the sides and that really makes a difference with lower buds.
i grow just over 5 foot plants ive swapped 2000w hps with 1890w cmh with cross lighting will cmh be no good for 5 foot plants ?
will cmh penetrate right to the bottom of a 5+ plant
Its not the height of the plant that matters, its where your canopy is. I'd say mine penetrate about 10 or 12 inches before I get popcorn buds that I would rather not have. My plants are about 2 feet tall but lollipop and topped many, many many times.what plant heights would be optimal with cmh
Man them girls are leggy
Man them girls are leggy
What strain
That where I bought all my cmh stuff.
