fan

I'm not sure if this makes sense or not but my grow box is at 73 degrees when my lights on but I added a little computer fan for strength of the top roots but it made it 102 degrees in there any ideas

Take out the computer fan.....

Yeah I am but shouldn't I have some sort of fan for stem strength so when it buds it don't just fall on itself?

Ok I figured out the problem its stupid but makes sense I have a fan that can be hooked up by USB and my exhaust fan has a hook up so when I turn the fan on it it pretty much slows the exhaust fan to a stop

I knew it
