Really hope you didn't spend $8000 on lights, for that kind of money I could build out my entire spare room floor to ceiling and still have money left over for genetics and a personal grow tutor.
My guess is you bought the tired old dogs off of someone else who was smart enough to know that technology has improved and had decided to upgrade their lighting. As I said before I'm new to growing, but I've already grown flower that is way better than anything I smoked as a kid.
@Lifer99 Do your homework and decide how much you want to invest in growing, plenty of folks here have grown nice flower without spending a fortune.
