MacGyver Attempt for Ventilation

My grow tent is a 2x2x4 PVC frame with plastic sheeting/mylar on the inside-nothing fancy but it’s my first grow. HLG100 LED for light and seedlings are doing ok.

I have a small fan in there keeping air moving but would like an exhaust option-I have a small 4 inch desk fan and some foil duct tubing around the garage. Would it be feasible to rig the desk fan up top inside the tent, connect it to the duct tubing and have that go through the side of the tent to vent outside?

Or is this a small enough grow that passive air flow with a fan inside on the ground is enough?

You will probably need the exhaust fan when the plant is bigger to prevent high humidity or temperature.

if you have good seal in small tent H is up for sure. you hit 90% humid in there without even trying. get a little rH meter. For a cheap solution I'd macgyver a 4" can fan on a timer and cycle on off every 15 mins especially after watering.

Thanks-it’s not airtight, humidity is around 30% per my little temperature/H meter. Trying to get that number up with a bowl of water with some cloth in it to wick. Appreciate the input
