Exhaust for 2x2 closet

Hey I’m just starting out was wanting some help. Stealth is my main goal so I’m setting up in a 2x2 closet with a lock. Will be using an exhaust fan with filter going straight into the roof and also an oscillating fan mounted on the wall. Will this be ok with just using cracks in the door for getting new air?

cheers

Do a test run without plants, you may find that it will get to hot in there and need extra intake holes/vents

You NEED to have a certain intake either passive or by fan. Always choose an intake fan weaker than your exhaust fan to create negative energy. That way you can be sure that you'll have absolutely no leaks regarding the smell. For example , i just set up my old 2x2 tent , and im using 2 fans , one for intake (4 inch fan) which is rated at 105m3/h (60cfm) and another one for the exhaust which is rated at 187m3/h (110cfm).

You might be fine putting a floor vent in, the space under the floor should allow some airflow. It does depend on the construction but there will be holes from room to room for pipes and wiring and possibly joists.
Worst case you put a couple of floor vents in the closet and a couple in the corners of the actual room to allow air in under the floor and into your closet.
