depending on which country you are in i would always know what it is you need before you go into a grow shop. im not speaking about them all, but some are just desperate to make a few quid and they will tell you that you need things you dont need, personally any 6500k should do ya( as frmiboi said). mine spends most of its time in the box, its the hps that your really gonna be using more so spend the extra money there. the shops might not be that bad where you are ut where i am you need your wits about you and shop around as the price diiferences where we are is unreal.
good luck with the grow.
