i got a 400 cfm vortex for the exhaust and just made a hole in the ground for fresh air. do i need intake fan for the intake or will the hole be enough air ?

it depends on a lot of things 90 angles in you tube how many watts you use ect... 400cfm is good it should work fine without but if not you can get a cheap booster fan and it will work great

A passive intake should work just fine, as long as your intake area is roughly 3-5 times the area of your exhaust.
