Doing new op and only have one inline fan and ducting, just for another few weeks till i can get more.
Would it be better to pull fresh air in or push it out? If my temps stay in check then would it be better to just pull in fresh air? Granted this is onky going to be fpr 3-4 weeks. Its a pretty big room too and not 100% sealed in any meana
 
Pushing air out seems to be a better method for filtration if that is a concern.

If not then I can't see a diff as the pressure diff you create will equalize any way it can.
 
If your room is properly sealed has proper air inlet/outlet vents, In the terms of air pressure...if you blow out the exhaust, air will be drawn in the inlet to equal out the air pressure. If you blow air into the room, air will be forced out the exhaust vent to equal pressure. The difference? Negative or positive pressure. If you blow into your room, it pressurizes (Positive pressure). If a tent, it will bulge. Any leaks will have plant stink pushed through them and bypassing any filters. If you pull air out of the room, your create negative pressure (a tent will suck in), and any leaks you have will leak in fresh air while the room air is being forced through the filter.
Air will always equalize unless your vents are not sized right, but you want negative pressure in your area to maximize your filter. Positive pressure air is forces out where ever a leak is and will be unfiltered.
