Flower with MH?

Always got the dual spectrum bulbs as well which can be used for vegging 'n' flower... it is just a hps which has been tweaked to offer a bit more blue spectrum.
 
HPS produces more weight, MH produces more THC.
The combination bulbs are going to get you a decent combination of both weight and potency. If I could afford dual arc bulbs for my lights, I would be using them. Cheers.
