I had two main goals when building this system, not to have stray light coming out the back or top and little to no noise. I don't have any stray light but the noise is not quite where I would like it to be.
The biggest challenge with having a completely sealed unit is heat. I have the Mag 9/return and the Dart/CL in the crawl space to reduce noise and to help keep them cool. I also have experimented with a exhaust system to get the hot air out. I suck it out from above the display where the lighting is and blow it out the side of the house. It works quite well now, it comes on when the MH’s come on and off an hour after the MH’s go off. When I was trying to get the sump drilled for the return I could only find a place to drill 1" holes and I wanted at least 1 1/2", so I got two 1" holes drilled and T it into the pump. After I had it drilled a glass company called me back saying they can go up to 3", oh well at some point I will be upgrading the sump and pump. Maybe  You can see the two black bulkheads in the back middle of the sump.  And in the crawl space you can see the pumps and plumbing. First the Mag 9/return and then with the Dart/CL.   I was originally using a inline ducting fan rated for around 80 cfm's and that wasn't doing it so I went to a 309 cfm fan I got from Chin Lee. Thanks Chin I haven't forgotten about that.  Here you can see the flexible aluminum ducting.   This is the old fan in the c/s inline with the ducting and then removed from the ducting.   New fan  I first set it up like the old one but vibrations were going through the floor.  How it is now.  I have it vented through the side of the house using a dryer vent.
