HPS are used for Street lights and lights in a parks outside somewhere; this is why when you look at the street lights(at least in my area) they are a yellow/ amber colour.

HPS are best for flowering, yes you can use the one at Home Depot or Lowes but if you get one from a Hydroponics store is will be specifly made for growing plants. Better choice.

MH are used for lighting up billboards at the side of highways or inside big buildings were they need lots of light. My gym uses MH bulbs. They produce a very white light.

MH are best for Vegging, yes you can use the one at Home Depot or Lowes but if you get one from a Hydroponics store is will be specifly made for growing plants. Better choice.


Most HPS and MH bulbs use Mogal sockets which i have yet to find at lowes or HD. Need to go and by this from an electronic store or your local hydro shop.

I doubt anyone will ask you what you are using this for. If anyone does ask just get creative. Dont freeze up like your doing something wrong.

not to sure about #2.

cheers,
