New to HPS, have a question

Hey, so I'm used to growing with cfls and now looking to switch to HPS, I am looking at the floralux 150w mini on htg supply.http://www.htgsupply.com/products/floralux-150-watt-hps-mini-grow-light

My question is this only comes with one bulb so I'm assuming you veg and flower with it, though I have seen hps systems that come with two bulbs(one for veg and flower im assuming) so is this a one bulb do all system? Thanks

MH for veg through the stretch. Then HPS they've got finish bulbs also very late in flower. The last 10 days or so I believe. I got a pair for free I'm going to be trying in a few weeks.

Now if you want to go CMH then one bulb will be fine. Just make sure you get the right one. It's the bluer of the 2 but can't recall the numbers on it.

They last much much longer also.
