If a 1000w de hps covers a 4x4ft-4.5-4.5ft area, without creating hotspots, how many lights would you need to cover a 20x20ft canopy?
Would it be 28? Or would that be over kill? 24 maybe?

See, but then I thought it was like 25-50w per sq ft so I was thinking maybe 20 lights. Just a little confused. I was leaning more towards the 20 light tho

Sounded like you wanted 60w/sq-ft with the 1000w/4x4 formula, so if you don't want that, then let's work in the reverse and let us know what watt per square foot you're after.

I think the gavita De's cover more like a 4x6 area or something like that, rectangular, so somewhere around 16 or 17 DE's.

Do any of you use the pattern overlay with the lights? I’m used to a 4 light area of plants. Since I’m adding more in a certain space I’m trying to find the optimal amount of lights for that area.

So like 16-17 Gavita de’s are putting about 50-60w / sq ft? For a 20x20 area at least?

On high wattage setting they are able to cover 24 sqft.

20x20 = 400
400 / 24 = 16.67 lights minimum.

Problem is the odd number and spacing so I would probably go with an even number of lights.

What would you consider maximum?
