just explain why he needs a light mover for a 4x4 tent? if he gets a 1/2 decent hood and a diffuser for his bulb explain how 2 600w's would be more efficient then 1 1000w lets compare please
1200w of power for 150k lumens
1000w of power for 150k lumens
double your overhead costs on ballasts bulbs and hoods so lets say he is payin 300 a piece for a 600w ballast then another 150-200 a piece for the hoods 100 a bulb takes 200 watts more power for same lumen output lookin at what like 1200-1300 bucks startup before a plant even grows a 1000w setup can be 700 out the door
so again ill ask you to explain how 2 600w's is more efficient than 1 1000w seein as to how you explained nothing but the size of his tent which i already knew
