HPS and MH bulbs

  1. I'm looking into starting my very first grow, as I've finally got my hands on my own place, but there is still one thing that needs clarifying.

    I know all about the different advantages of MH and HPS, but what I haven't seen anything on - is whether you can simply buy a bulb and put it in an existing lamp socket (provided it's the right fitting), or if you have to actually need to buy a whole new system?

    Apologies for the newbie question, but I've only been reading about growing for the past couple of days.
  2. A HPS or MH light bulb requires a ballast rated for that wattage bulb in order to start the light and keep it running.

    The ballast contains capacitors, transformers, and an ignitor for the bulb.
  3. Thanks for the quick reply, that's all that I needed to know :smoke:
