HPS - High Pressure Sodium
MH - Metal Halide
Both can be used. HPS is better for flowering since it provides the red color of the light spectrum
MH are better for vegging since it puts out the blue color of the light spectrum

usually requires a seperate ballast and hood unless you are using a conversion setup

n can u tell me wut a ballast is n tha hood is wut da reflecters? sorry for all da questions I just needed to ask
Yeah I got the fancy switchable kind. You get one ballast about the size of a shoe box and is real heavy. It has a switch on it which says either MH or HPS depending on which way it gets flipped. It comes with two bulbs one MH and one HPS. Only way to fly in my book. Aint been using the MH part of it much lately since I have mostly been vegging under CFLs but it handy to have it in case.
dependent how meny watts you want but i got mine 400 watt switchabe digital ballest for 150 it included the hood and both HPS and MH lights with free shipping and the best part is there is no buzzing like there is with the regular tipe of ballest i love it i run it all day and use MAYBE 15 kilo watts a day running it
