Ok lights are a little off. So got pics erly.(reminder fix that). Do I guess I'll start fir the beginning. The intake
This is the intake for lights from my garage.
This is the intake next to AC. Notice now there is a filter over the opening?
Next is the inside view same intake. AC is as high as I could get it
Next is my cooling side of lights. Yes I need to get rid of the cheep duct but money is tight. Will hard duct the top soon.
See how it feeds 1 side of the lights. Not in a line! This is where the filter comes in play. But talk about that later.
Now the exit side notice it's the same as the intake.
This is the 8" fan pulling the cold air thru all the lights.
Remember the filter? This creates back flow. Making the air have a draw. So all air flows threw the lights the sum not just the first light. And all duct is 6" to a 8" fan.
This is where the 8" fan leaves the room. Duct down to a 6" duct snd out threw the attic.
And as the AC is up high my dehumidifier is on the ground. It is a cool air. Meaning it has 2 coils. One to cool the intake and another for what it dumps in the room.
I maintain a negative air flow with this. A 6" 440 cfm filter. So far you only seen the flower room.
Now in the veg room is this. It's set to a temp gauge so only runs after 80degrees.
This would make a negative flower room and a positive pressure veg room. But I also have these.
Each running 60 cfm fans. So there not sucking my walls in but can keep my door shut. It's not top of the line or over the top. But can handle over 3000 watts in a 14x14 area with inside temps of 80 and outside temp of 110.
Hope this gives you a good idea of easy cooling.
And thanks scooby for working with me to go this far.
