LOL. How do you know I have ADHD with enough OCD to keep it in check?..
… well let me tell you it’s easy by checking out my 4x4 
.
Main Fixture: Mars Hydro FC6500
Side LEDS: Undercanopy when needed, 3x 3000K 40" bars.
Supplemental Lights: 2x FarRED Led pucks (for flowering, set to turn on for 15min right at lights off), & 1x UVB Led Puck (trich booster, turns on for 3 hours in the middle of the 12 hour lights on).
These pucks are tucked into the bar fixture and once Mars Hydro get their shit together and have separate on/off switches for their UV/Far Red bars I’ll upgrade to those 
The 2x2’s along the walls used as reinforcement for the walls negative pressure and as mounting points.
Tent Floor: Insulating foam under the tents collection tray with 2x large size seedling heat mats above the collection tray in place to ensure warm roots. (I have a very cold basement in the winter).
My controller board is very Clark Griswold.
Interior Air Movement: 2x Tower fans & 1x cyclone fan at the roof aimed down.
Primary Exhaust: Single roof 6" vent pulled by an AC Infinity Cloudline T6 (inline #1) which is automated via it’s controller.
Secondary Exhaust: Both top side-wall 6" venting ports are connected together via a “Y” duct fitting which is being pulled by an AC Infinity Cloudline T6 (inline #2) which is automated via the same controller as inline #1.
This is an older image when I still had the duct-booster in place before I got another Cloudline T6 when i when on sale. The silver booster is now in a different tent altogether .
**All my exhaust vents directly outdoors with baffles in play to keep the cold & animals from getting back inside. 
Forced Air-In:. As mentioned i have a cold basement, so I made a “heated air lung box” out of plywood scrap which feeds hot air from a small oil heater forced into 2x tents via a “Y” duct fitting with an AC Infinity Raxial duct-booster.
All the best of success with your set-up @Growgrassblowglass !
