CanCom is loading painfully slow so I didn't read every thing but looking at your first posts one thing is worth mentioning.

You have 2 fans for intake and one out.
Now, these are computer fans and not very powerful but in principle that's a no no.
You want underpressure in your grow room absolutelly not overpressure.

Why?

Well, a few reasons.
You want all air that vacate the room to be hot and all air that gets in cool. If you have an overpressure air will get out everywhere instead of just where you want it, close to the top. This will significantly raise the temperature in the tent.
If you have 3 fans designated for ventillation you should put at least 2, preferably all 3 for exhaust close to the top of the growroom and let the underpressure suck air in as low as possible.
This is much more effective and also make sure that you get as much CO2 rich air into the tent as possible = healthier plants and bigger harvest.

Good luck with the grow.
