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

Ventilation on schedule?
If I put my ventilation on an hour on/hour off schedule to raise the RH (RH when cold is around 30%) and help relieve my heaters a little, will it be detrimental to the environment? I've got heaters on controller, Temp is steady with ventilation on but wil be expensive in winter

I made a firebomb?
Is it a fire hazard if 5v computer fan is jammed and the power is on for 2-3 weeks? I'm far away from home and I have camera in my growbox. A tape has fallen to the fan and it is not rotating. Can it heat up so much that fire starts? Should I drive 1600km for that?

Gathered a new tent temperature inside allows you to do without blowing. How much will affect a plant that grew without wind at all

High humidity
Hello. Even with a dehumidifier and a 24-hour extractor, the humidity is still above 70% and one of the plants is almost in the flowering period. Can I add expanded clay on top of the vase to see if it lowers the humidity or putting more perlite will solve this? Thanks.

Is this clawing, or just droop, (pots fairly dry)And why can’t I get RH below 70% with more than adequate ventilation, I’m recalibrating my hygrometer in the meantime.

Hey, I added a CO² diffuser bag in my tent. do you have any tips for using it? (smart bag from servovendi) I read somewhere that you have to disable the extractor for the bag to be effective. It's true ?

Circulation / Exhaust
Getting ready to install carbon filter; found myself wondering if growers typically leave their filters/exhaust/fans on during dark periods? Up to this point, I've had everything on one power-strip/timer: circulation fan, exhaust fans, and lights. Should I keep anything on 24/7?

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?
