Ceramic Metal Halide

Recommended Posts

I have just seen the light spectrum of the ceramic metal halide from Philips anybody useing them? i was reading they have high ultra violet output, good for sativa's and can be used right through the grow. Plus they run off a hps ballast. I want one or two for my ace seeds, sativas if they are as good as the sales pitch. Any input most apreciated.

Post up the spectrum.

MH fail to provide in the red spectrum. UV and hence for veg they are supreme.

However, Sunpulse (the best MH on the market imo) supply a 10K MH bulb that is supposed to be used in the final stages of flower.
