one plant trained right beats three untrained every time
running a 2x2 closet for a while now and the biggest lesson was plant count. less plants means less smell surface area, easier to manage the canopy, and way better airflow around the one you actually dial in.
tried squeezing three plants in there once. disaster. odor went through the roof, filter couldnt keep up, and the yield was worse than a single well-trained plant. lst and some gentle topping on one good pheno will fill that tent wall to wall if you give it time.
for smell, the filter setup matters more than strain choice most days. inline fan pulling through a quality carbon filter, sealed as tight as you can get it. no passive holes. tape the zipper seams if you have to. any leak point is where it escapes.
that said, strain still matters. purple punch and certain kush genetics run much quieter than hazes or anything tropical. if you're in a sensitive situation, pick accordingly before you even pop the seed.

Gonna push back on the filter > strain thing a little bit. In my experience that flips depending on what you're running. I had a single GSC pheno that was breaking through a brand new filter at week 6 just sitting there, not even disturbed. Meanwhile my buddy runs straight hazes next door and you'd never know. It's so pheno dependent that blanket rules about quiet strains get people into trouble.
Like yes, purple punch on average runs quieter. But the loudest plant i've ever grown was a "supposedly chill" indica dominant cross that smelled like a gas station bathroom crossed with rotten fruit. Incredible smoke, nightmare for discretion.
The one plant training point i agree with completely though. That part is just correct. A 2x2 with one properly dialed pheno and good veg time will surprise you every run.

the filter vs strain debate is interesting but i think you're both kind of missing the bigger variable which is canopy disturbance. my 3x3 gets checked and trained pretty regularly and that's when smell spikes hard, way more than passive offgassing. if you're in a tight spot and doing daily lst adjustments you're basically wafting terpenes around the whole room every time.
for a 2x2 running one plant that's getting hands-on attention, your filter and fan need to be sized for active work sessions, not just idle running. a lot of people size their filter for "normal" and then get caught out when they're in there bending branches around.
on the one plant thing though, i do agree with the core point but i'd push back slightly on the time part. if you're running an auto you don't always have the luxury of "give it time." you get what the plant gives you on its own schedule so dialing in your lst technique matters more than with photos. you can't veg forever waiting for canopy perfection. i've had runs in my tent where i got a beautiful even canopy and runs where the auto had other plans and there wasn't much i could do past week 3.
