Stupid me...

I accidentally ordered a 400w hps growlux bulb without knowing I needed a ballast and ignitor. Does anyone know of a very cheap kit that I could get? Up until now I had been using household things for my cabinet grow with three babes in it, but I'm going to need more lighting soon to flower. Thanks

Actually checked the forum and found my answer. Thanks though. xD

lol.
