Light Spacing ?

[Bobbybuzz]

Hey fellow growers ! I have 2 CMH 315w Single bulb grow lights in a 4x8 x 8 tent with 4 plants 2 are Afghan kush and 2 are white widow. I also have a cheap 1000w led !? My questions are how far apart should my lights be ? Should I use the led also ? I'm talking about veg and bloom
