How much ventilation does 2 tents need?

[pandor]

If I have 2 tents standing alone in a room, do I still need fresh air from the outside of the house pumped in to the room if the tents have strong intake/exhaust fans? The door to the room the tents are in will always remain open and the air conditioning unit to the house seems to pump in a decent amount of filtered air from outside.

for better or worse overall, i do better when pull air in,my plants grow better, they got dust shrooms and other screens for sale to filter air ,maybe just get some gas or burner.

your good if the room stays cool enough. use air cooled hoods and suck heat from lights to outside.
