I run one that blows over the top of the soil and another over the canopy. Don't see an issue with what you're doing

Brauche ich unbedingt einen (Schwenk-) Lüfter in meiner Growbox?
Habt ihr schon mal ohne (Schwenk-) Ventilator in der Growbox angebaut? Wenn ja, welche Erfahrung habt ihr dabei gemacht? Ich möchte nur ungern einen Ventilator einsetzen, weil das vermutlich die Lautstärke der Box deutlich erhöht. Schon mal vielen Dank für eure Erfahrungen.

2x2 Circulating Fan
What is the best circulating fan for a 2x2 tent available on the european market? I bought a Secret Jardin MO20 oscillating fan, and I highly regret it because I have read several reviews mentioning that it can catch fire. Is there any other good alternative for circulating air?

Maintaining VPD
I've got my photoperiod doing well in a 2x2 tent. I'm trying to regulate my VPD with what I have on hand. Currently I'm running my exhaust fan for 8 minutes every hour to get an average VPD around 1, but I'm concerned about the swings. Am I micromanaging?

Smell through filter exhaust
The smell inside is quite strong and is coming through the filtered exhaust. Is this normal, or does it mean I need to replace my filter soon?

How crucial is an exhaust fan and a carbon filter?
I cant find anything in my country as a kit, but would buying them piece by piece work? Example something like in the photo connected to an air duct and then to a carbon filter? Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

Overheat in tent? Measuring Correctly?
HID lights on seedlings day 2 (25 cm dist.) I was alarmed by temperatures rising since yesterday to 35 despite exhaust & small fan inside tent. Tent doesn’t feel overly hot. moving sensor to above light it reads at a good 26-27. What’s the best way to understand tent temperature?

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?
What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?

RH 90% during Flowering!
I have a problem with RH. I am at the 3rd week of Flowering and I'm struggling to keep my RH down. Today it was 90% when I opened the grow box. I have access only to a window. Is it better to suck air inside or blow the exhausted air out? I can't do both

Smell at 2.5 weeks?
Is it normal for a Quick One to smell strongly at 2.5 weeks? I only have one plant, and moved it out of my bedroom to the spare room where there are fewer clothes. My partner could smell it downstairs and the plant only just got its 5 tipped leaves.

couple quick questions
Do I need to close the flap to the vent during dark cycles? (Lights off during the day) and should I block lights coming from fan power, humidifier, dehumidifier, or indicator lights? Also do I need to use the carbon filter the whole time? should I ever have the exaust fan off?
