Growing vertical with 2 stacked 315W CMH lamps on screens in my 4 x 4 increases my footprint from 16 sqft, to 33.75 sqft.
My screens are 44" x 22" so that 6.75 sqft each.
Here are the 5 plants in the tent. This pic was taken early in veg.

I have changed my screens from plastic to Stainless Steel. The plastic screens would pull out toward the light where the stainless is rigid.

I have thought about 2 or 3 DE 1000 but not sure how would space them in 7x11x11. What’s your avg per fixture? I see people say they get 2 or more per de but is that dialed in pro’s or the common person?

My flowering space is 4x16 I got 4 of them.
I avg 3 a light .
If you can maintain a good environment 2 a light isn’t to hard. Do 3 + you’ll need to be on your A game .
4 is possible with the right genetics, I would love to see what I could to with 100 of them and 12’ ceilings .

Two would be easy if I could hit 3 per I’d be happy with that if not I already have some cmh tho and I’ve seen a lot of guys run cmh as supplemental to the de 1000 with good results so maybe two of each would be good that would be 2630 watts do you think an 18k btu mini would get it cooled? I hear 6000btu per 1k fixture?
