Hey yall, just have a question about my shed grow. My shed is 4'x8'x8' high. Im gonna load it up with at least 12 plants. with the room being rectangular, would I be better off with 1 1000 watt in the middle? or 2 600 watt lights evenly spaced to cover both 4x4 areas? a friend told me I should use a 1000 watt due to the lumens I will get, and it should cover the area. thanks in advance
I would go for the two 600Watters evenly spaced in a 4x4 area...enestially you will have more lummens the just one 1000w ... might even save you the necesity for a light mover !! Regardless... Both scenarios are optimum for some good herbage
600 watt HPS are the most efficient in terms of lumens/watt, so you would be much better off with two 600s.
Not necessarily true... If you read the thread I linked in my signature, I compare CFL to HID. Although this isn't exactly a CFL question, My research showed that the 1000watt HPS is more effecient than the 600W HPS by about 4 lumens/watt... Based on the argument for better light distribution, I'd say go with the two 600w hps also, but not based on any expectations of getting extra light output...
Yes, the 2 600w will suit your purpose. But of you do stadium grow, the 1000 watter will do just nicely.
I'd go with the 2 600s... doing a 4x4 and plan on 1 600, the two 600s should give you great coverage(and if you can go digital/electronic ballast)
