Airflow
6" Inline Fan + Speed Controller
Stage: All stages
$155
Stale air is where most first grows go wrong: temps climb, humidity stacks up, and mold gets a foothold in dense flower.
This 6" inline fan pulls fresh air through the tent and pushes the old air out, exchanging the full volume about once a minute. Plants get the CO2 they need and your canopy stays dry.
The included speed controller lets you dial airflow down for quiet nighttime running, or up when your room heats up in the afternoon.

Questions about this product
- Do I really need an exhaust fan?
- Yes. Without air exchange a closed tent overheats within an hour of lights-on and humidity spikes overnight, which is exactly the condition bud rot needs.
- Should it run all the time?
- Run it 24/7. Air exchange matters just as much in the dark period, when humidity climbs.
