Can you buy a ballast by itself? And if so can you buy it at electrical stores,or building supply stores such as Home Depot.......Or o you need to buy online, or at a local Hydroponic store??????????
Save your time and just buy one online...I've searched for places where I could get the ballast, ignitor, capacitor and all that junk seperately. When I actually found somewhere nearby and went there, the salespeople looked at me like I was crazy. You'd be better off just buying a kit online that comes already assembled.
