Hello,

Really getting different advice from google here.

Tent is 2x4x5
MARS TSL2000 LED
4 passive 6in intakes
390 CFM 6in exhaust

So, what is the best route here, do I really need intake fans, and if iso, does it need to match my exhaust CFM?

Thank you!!!!

think exhaust fan will do the job. That would suck the balls off a fly if it gets too close. 2x my exhause and half the area. Best of luck on a successful grow.

So you’re working with 40 cubic feet of air, your CFM of 400 (max) will be 200 with a carbon filter, 100cfm @ 50%, 50cfm @ 25% etc. With your fan set to 2-3 and an open intake port, you should already be cycling more than your tents capacity for air while replacing it with air sucked in through your open port, so I don’t see a benefit in implementing an intake fan. That said, you could do a makeshift filter of some sort for that intake vent to keep pests and light from creeping in. Happy growing!

Awesome feedback, this place is really great! I went big with the exhaust because I'm going to use a carbon scrubber eventually.

Thanks for the feedback and wishes y'all!!
