Looking good brother
@Hybridway !
I couldn't find your post where you said half these led folks are wrong about the heat load contribution vs an air cooled hps but I could't agree with you more.
I saw it first hand - had an 460W inda-gro hanging and swapped for a 1000W hps in a cooled hood and temps dropped substantially. "They" can talk all the nonsense bullshit they want, Air Cooling WORKS
The Vero 18 DIY setup I played with was the same thing, plugged it in and was like "Jesus Christ that driver is fucking HOT"! Makes no sense why the led's being built for indoor rooms don't have a remote ballast option?
Anyways, on the HID's I prefer the 6" Raptors cause #1 I'm cheap like that and #2 I feel you do loose a bit less light down the ducting.
I like mine set up so fresh air is entering each hood, not pulling the hot air from one hood through the other.
I am running 2K of hid and have 1 14" MaxFan that is like 200W running my whole flowering operation.
If I had a large room I would build large intake and exhaust manifolds above so cool air would enter each hood just the same
