New room build, typical ventilation or hybrid sealed?

[BCBudGrowr]

So I'm currently building a 12x8 room that will have a 4x8 growing table in it. Using quantum boards. I originally planned to have a 6" filtered passive intake with an 8" exhaust filter and fan. Like most tent set ups. The room is in my basement and I've had to use my heater in my 4x4 tent down there. Temps are normally around 16-18c with rh around 35-40 naturally.

It was suggested to me that I should consider putting gasket sealed dampers on the intake and exhaust to basically "seal" the room, use the 8" carbon filter and fan as a stand alone room odor scrubber, then use a 6" fan for exhaust and a 4" fan for intake. Then have the intake and exhaust fans run for cooling on a heating/cooling controller. Controller would turn on the Heater as needed and if it gets too warm, the controller turns off the heater and turns the ventilation fans on, refreshing air in the room until the set temp is reached. No co2. Then a dehumidifier and or humidifier to manage humidity.

I think this might allow me to better control the environment..

Anyone else running a room like this? Thoughts?

One other question, do you think the scrubber will do enough for the smell or should the exhaust fan also have a carbon filter?

What you want is as little temp fluctuation as possible if it warms then cools over and over may stress the plants it should only warm after lights go on then cool at night if that makes sense to you.

Plants can handle heat it does get hot outdoors in summer but they cannot grow properly in cold temps it will stunt them severely.

I run 800 watts of sodium bulb during summer months without cooling only use fans and my grow room temp rises to 95 to 99 some days but because it does it slowly over time and the temp change is not drastic they grow like crazy.Plenty of fresh air and they thrive.

I am lucky my neighbors can legally smell my grows.

Really nice. Today I visited my local grow shop and talked to the owner who has lots of experience and I've decided to stick with the original passive 6" filtered intake and 8" carbon filter/fan exhaust, but putting an fan idling controller (TV12) that you can set day and night temps and it will adjust the fan speed automatically. It triggers on the lights going on/off. Saved me some bucks and I think it will work well. We'll see! Thanks!
