I have a nice little grow room with most of my conditions at 90% except the one problem i have, Airflow.
The room i grow in is not square but i got a metre square easy, problem is its between 2 other walls in my house and the next door so basicly no external wall, which mean no extractor fan.
Air purifiers are cheap and i wonderd do that actually help if you have bad airflow?
Not sure if they change the air like a extractor fan would or maybe the filterd air would be the same as new air?
Anyway if anyone know would be appriciated
