MH is all right for the generally better UV-B radiation output -- which works to improve the quantity of THC on and in your buds.

But as far as the lumen radiation output -- the shit that fattens the buds -- HPS is your lamp.

You won't get the quality with the HPS, but you'll get the quantity.

And vice versa with the MH -- quality, not quantity.

It all falls on what you -- the grower -- wants out of their plant.
