By my definition of great, I would say yes.

But the MH is more for the UV-B rays than anything else.

My sq ft area is 3.75 so my HPS alone would do nicely for the flowers. The MH is an added spike to try and crank up the resin production. But to do it properly I need another HPS 250W to add to the mix so I can get my 2:1 ratio that I really need.

Course I could drop the MH down to 150......hmmmm....

Good Idea.. thanks bunches
