CMH with LED

ive ran this combo for about two years.

I would add the 3000k CMH/LEC about 3 weeks in to flower.

1000watts of 3500k cobs and two 315's

get a CMH with the ballast not in the hood, like the phantom or something.

i had very good results, still a bit shy of 3 1k hps but CMH's IME bring out a lot of color which is good for jar appeal.


I'm now using 3k QB's and not the CMH for awhile. ill see how that goes maybe ill go back.

How are you finding the quantum boards?
Since you have used both cobs and quantums, which dobyou prefer?

Which do you think would preform better with the cmh.
