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,

Jonesy2010 Reviewed by Jonesy2010 on . Two Questions, some answers? 1. What are HPS lights REALLY used for, i don't have a credit card...and don't want one...and i don't put my money in banks. fuck, that! sooo...a local electric store has a nice ballast...that holds both hps and mh. the bulbs i can get at lowes, both 400 wats. so, what do I tell them I need it for?...i don't wish to share my business with them. 2. at the moment, I have a CFL light from petco that is 65 K. Two bulbs, 6500 K blue acetinic light...and a 65 w cfl..just regular...in Rating: 5
