Was not trying to disrespect anyone who uses the metal halides. I know there are mh bulbs tuned for blooming. When I first started I used a mh for everything because it was all I could afford at the time. I eventually got a hps and the results seemed better in my case for the bloom cycles. I guess it all boils down to what works for you. There are so many methods out there to grow the erb and its just a matter of sharing with others,what works for you, so they can succeed in their quest. Unless you have a hemp plant or some strange strain growing there, maybe experimenting with the light times will help.
