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

Keeping humidity up and steady (Fan speed non adjustable)
How do i keep humidity up and steady? My exhaust fan has no speed control and drops the humidity. I have my humidifier on almost full blast(not full blast because of i dont want it to overheat) a wet towel and a bowl of boiled water. Does the exhaust fan need to run in veg state?

Humidity vs airflow? 8 day seedling.
Humidity VS airflow for 8 day old seedling, which is more important? My seedling is in a propagator with 60-65% humidity. Outside the propagator is at around 40%. I'm waiting on my humidifier. I'm going to raise it with a wet towel and containers of water. Should she be in tent?

Fan vs Fanless LEDs
How effective are heatsink LEDs? I'm not sure if I should go with fanless (like Mars Hydro SP150) or with a fan (Mars Pro II Epistar 120). I struggle with heat, when the tent is closed it gets to 29-30 degrees with humidifier in full swing (HID lights) and I want to close it soon

Set Up Tent
How should I set up my carbon filter, exhaust fan & air ducts? I’m in limited space right now but want to make sure I get good air circulation still. I set it up the wrong way the last time I had it up but it was already up so I just left it. Also, my fans. Where should they go ?
