I'm obviously biased and a big cmh fanboy because i love them, but
from what ive seen compared to led's is night and day. Especially taking into
consideration the light output and power consumption.
In my opinion the cmh light gives the best buds for power usage i have seen to date.
Most yield for least power usage, and i like that. Ive used the phillips bulb the whole
time and its seems excellent for all stages of the plant.
I think to get similar results you would need more than 300w of led power
and i dont think it would be cheap. Also the life of the product is another
important factor. Seems to be a lot of led's having problems and some of them
are not as efficient as everyone thinks.
Not putting down led's, just not my thing.
Ive seen a lot of people mixing lights, thinking theyre saving power.
4 cfls, a 150w bulb, blah blah blah. If you add some of these setups
up in wattage and power consumption, some of them are using more
than they would if they just put a 315 in there and be done with it.
And get better/more product too.
Suppose thats the beauty of everyone having different grows though
Keeps it interesting.
