two plants, one filter, zero smell complaints

running a 2x2 for about three years now. the single biggest upgrade i made wasn't the light or the medium, it was sizing up my carbon filter. people go cheap on the filter and wonder why the hallway smells like a dispensary.

my setup is a 4 inch AC Infinity with a filter rated for way more cfm than i actually need. overkill on purpose. negative pressure in the tent means every bit of air goes through that carbon before it leaves the space. no bypass, no leaks at the zipper, no excuses.

for plant count, i stick to two in the 2x2. tried three once and just created problems, airflow got restricted and i had a humidity nightmare in week 6. two plants trained well will fill that canopy without the headache.

the one specific thing i'd tell someone new to small spaces: seal every duct connection with aluminum tape, not just the clamps. clamps loosen over time. tape doesn't. took me an embarrassing amount of time to figure out where a small leak was, and it was right at the intake collar.
