I want to get a simple 150w hps because I didn't like how my cfl's in conjunction with my bad soil pretty much stunted my plants and they will only probably produce 2 grams so I'm pretty much done with cfls. Friday I will be purchasing a 150w hps since adding 6 new cfl's plus the reflective hoods will add up to about the same as a 150w hps with half the lumen output and possibly producing more heat since I have a closet grow. Only thing is looking at the picture I'm confused at how they work and if i have to do any sort of extra wiring. Also one website is where I want to buy the ballast from but the other website has a cheaper 150w bulb so my next question is it good to get your ballast and bulb from two different places? Below is what the pic from the website looks like and it looks confusing lol. Someone please help me out here
