Ok so I have a 5x5 tent with a 1000 watt hps. I have a 6 inch 440 cfm exhaust fan that runs through a cool tube and then outside. Currently I am just opening the 3 or 4 intake flaps around the tent and letting the 6 inch suck fresh air in. Question is should I have a intake fan bringing fresh air in? If so how many cfm. My temps and humidity are pretty much perfect.

Ok. Thanks. A friend was saying something about negative pressure as my tent is sucked in a bit from the 6 inch.

Negative pressure will force your exhaust fan to work harder than it needs too. Unless you’re able to leave the flaps open during lights off. I had to add an intake fan dispute what everyone told me. It all comes down to what you’re needs are like chemistry said.

If it ain't broke.

If I didn't need to run an intake fan I sure wouldn't...

RIGHT! An exhaust fan is already noisy enough..
