Well that is one of "The best compliments I have ever had". So thanks.That's the best grow Ive ever seen. Its big, it has very very good room construction (with two floors ) and those roots on the previous site are absolutely amazing. Don't know how do you manage, but i like all that I don't know if you already mention but how much fans do you have for intake and outtake and to where do you pump and suck the air? How much cfm does that fans have?
Mange it? It's constant.
Well let's see.......Ventilation huh?
I have 2- 6 inch passive intake hoses (no fan) (in the summer I use an intake fan on one hose) coming into the lowest section of the room, 1 - 8 inch 750 cfm exhaust for lights, 1 - 6 inch 450 cfm, 1 - 4 inch 180 cfm and several BATHROOM type exhaust fans for misc. heat extraction. Plus I have 2 AC units and a dehumidifier.....each with their own exhaust fans and everything blows out through the attic or roof eaves.
I'm in the process of designing some sort of heat exchanger to eliminate half the fans. Way to many fans and 90% of my ambient noise comes from ventilation. If I can eliminate fans.........I can eliminate noise. It's not overly loud........but it's there and I don't like it. I would prefer to go NINJA !!
