...what's wrong w quantums...?
My recommendation would be to get a cheap 1000w kit from amazon like the ipower setup, or used from CL, I scored the other day and got an 8" original blockbuster hood, eye hortioux a killer quiet inline fan name brand and a name brand ballast for 100$
I have a double bulb, not double ended, double bulb 315w cmh so 630 total watts, it isnt air cooled tho, if you want I can sell it to you for 80+shipping. Its brand new only turned on for 10 mins, has 2 Phillip's agromax
