think of a cross , the plants in the middle and theres 4 lights , placed at the courners , the lights hang vert , the plants grown hydro in the middle to 4 foot tall and trimmed plus staked out to maximise the light , flowered if grown nicely will see the kilo assuming its done nice with the right strain
, whats up kid, i sent you some advice already, similar again to what the others have just said, 1000w to strong, blueberry might be to much 4 u starting off etc . .
