Got my dandy little DR150 set up but I'm trying to figure out which way I would like to configure the ventilation. Hopefully my babbling isn't too confusing. My specs are as follows; DR150 4'11" x 4'11" x 6'7" SuperSun 2 Hood 1000w HPS Ballast (will be getting a conversion bulb for veg) Can50 ( I also purchased a small Odorsok filter as a secondary filtration unit in case I decided to run the ventilation for the hood separate from the main Can50 filter) 6" Inline Exhaust Fan I was thinking that I could use the A/C duct system for my fresh air by keeping the unit on the "on" position so that air continuously blows through (2 a/c units on the house). Or I could just use the vent at the bottom of the tent as the intake for fresh air from the room itself and make the system a pure passive intake? I also have to think about cooling the hood. If I used the air from the a/c system, I would be worried about condensation forming because of the cold air (will be warming up very soon here). I then though about possibly connecting the exhaust portion of the hood to the ducting for the Can50 filter and exhaust fan. I was curious if this would create enough of a negative pressure just to pull air through the hood? If that wouldn't work, I could also just add another exhaust fan on the other side of the ten to pull air through the hood then connect the odorsok filter onto that to ensure no odor leaks through the hood ventilation system. Hopefully these pictures aren't too confusing. Any and all comments and suggestions are welcome Thanks!
