could someone help me on the usable light coverage differences between 400w,600w & 1000w hps/gh systems? i am trying to figure out how many fixtures i would need to cover my grow beds.
I have 4 sets of indoor grow beds that are roughly 5' x 5.5' each. what i am trying to figure out is the best way to cover the beds for maximum growth without over buying these systems. These beds have no other lighting. This is going to be the primary light source.
this is a similar system to the one i will be building.
thank you for all input!!
