 The Exhaust System (It sucks)
The heart of our system is a 1200 cfm Vortex tied in with 10" hard pipe and elbows. It feeds a 12" phat filter mounted in the attic above this room. Think of it as the lungs of the beast pulling all the cool air through the hoods and across the bulbs. The hot air is then forced upward and into a large carbon filter that prevents any smells from being broadcast outside the grow area.
You can see the new hood hooked up with wide sweeping turns with no restrictions.
Since this room is supplemented with CO2 all joints are sealed with tape and all flanges were caulked and sealed using silicone. This may seem like over kill at first glance but as I type this its over 100 degrees outside and while running 4400 watts in mid summer our max temperatures are staying under 80 degrees.
Another 6" tap travels into the veg room to vent the 1000 MH hood notice I used hard rigid flex to reduce friction I am a good ways from the main trunk at the end of the run its always good to go big on the last run. This is the very last connection on this run and the hood is pulling free from the room. This makes up more of the supply air needed by the large Vortex fan. This causes the entire area to be negatively pressurized which prevents any escaping smells.
This garden will be capable of supplying Edibles, Tinctures, and dry herbs to patients in need.
