While a grow light is off, does a in-line fan need to run? Ive heard it both ways and not too sure.

I run both my inline fans and oscillating fans 24/7 while I have a living plant in there. So in my opinion, yes, they should be running at all times to ensure proper air flow & air exchange.
Now, you could lower the speed of the fans a bit when they sleep if you want, but you need to exchange the air when they sleep, as this is when they exhale co2. Just imaging You were living in that tent, you would want a constant exchange of air to be happy.
Proper air exchange and air flow, and avoiding massive swings in RH and temperature, will give you the best chance of Never getting White powdery mildew, mold, bud rots, etc.

I like it.
We are investing in a inline fan soon and we’ve been worried about the noise at night while we sleep. Turning it down should help with the noise!
Excited for the fan. Feels like our setup has come a long way!
Ordered some “air-pots” today, should be here monday! Very excited for those as well. Done a ton of research on them and it should make the plant very very happy!

Nice. My AC infinity fans are barely audible… my 4 inch fans are at level8 or 9 and I can’t hear it much… The oscillating fans are louder. The loudest is the Fan on top of my tent blowing on the power supply for the light to keep it cool.

Haha, damn! That light must be pulling some power out of the wall!
When the light is at max, it pulls 300 Watts, not all that much, but the power supply gets hot. That is why I moved it outside the tent. Keep a fan on it to keep the power supply cool, thinking it will extend the life… but I could be just wasting money blowing a fan on it… hehehe

When noise is an issue buy a larger fan than you need and it will run quieter . . . you can run on a low setting and still move as much air.

No you’re not wasting electric doing so. What your doing with the driver and the fan is the best thing you can do to extend the life of the driver, heat is a killer of electronics. The cooler the driver and higher voltage the more efficient it runs.
