Use my fan as exhaust or intake?
Fruitgroweranswered grow question 6y ago
Exhaust always necessary, intake for a small amount of plants is enough just opening the door daily...

If door open than Intake. Becouse the breeze will move plants and they will become stronger. Thicker main steam

HumiditéHumidity varies quite a bit and I invested in a humidifier but it doesn't solve the issue. I have 2 fans and two passive intakes, but I think I have too many plants and I'm in a basement. Thank you very much, humidity is not good for flowering.

I made a firebomb?Is it a fire hazard if 5v computer fan is jammed and the power is on for 2-3 weeks?
I'm far away from home and I have camera in my growbox. A tape has fallen to the fan and it is not rotating. Can it heat up so much that fire starts? Should I drive 1600km for that?
