How many 1000W DE Hps lights for eight 4x8 tables?

[Oklah0ma]

Getting a commercial grow started and am not sure how many lights to put in my flower room for eight tables. I'm leaning more towards two 1000w De Hps per table. We will have plenty of overhead space to hang accordingly.

I'm in the 3 lights over 2 tables camp, but I guess it depends on orientation

What kind of orientation is needed for the three over two to work?

Two tables, end (4ft side) to end, maybe with 6-8 inches between. I grant my DE's 4' x 6' of prime light

Well, two 4x8 tables would be 64 sq

I misread your first comment, 3 lights would do for 64 sq. Would my tables need to be touching then?

That sounds like a great idea. Thank you.

General rule of thumb is one 1000 watt bulb per 4x4 grow space with approximately 6 plants per bulb in 5-7 gallon pots .

All I can add is if power consumption is an issue, ( cost, available power, etc), a 6 foot light mover with one 1000W fixture over an eight foot table works reasonably well.

2 per table

2 x Gavita 1150w DE per 4 x 8.
