I'm assuming those are e-Papillon 1000W lamps? Can you give some comparison yield wise to your other 18KW standard HPS fixtures? I'm replacing a room about the same size as yours with them and I'd love to get some insight that I made the right decision.
Haven't finished a room with them yet, just flipped two rooms two days ago. If I had to guess, the yield will be just as good if not better then normal hoods because of how bright the lights are. They also have a different spectrum I guess that is better for plants. I cannot stress enough how bright these things are, everyone wears sunglasses in the room. It's a funny look, we bought these cheap uva glasses and they look kinda like the old oakley blades. Everyone looks like Mark Mcgwire from the 87 A's minus the steroids.
We're trying out something with the dry room I saw a friend do. We built a sub floor with a bunch of small holes in it with fans underneath the sub floor sucking air into a lung room where we have an AC, 2 can filters and a dehu. Then we have fans blowing from the lung room through the ducting where it will travel down past the plants drying and back through the floor. Gives everything in the room a nice even dry so far.
