I use this as a floor fan to move the CO2 and H203 around as they are heavier gasses. It used to be my intake fan, but we are now sealed up and runnning the gasses.
I’m in the same boat, I went with a shop vac blower fan, kinda sweeps the floor and into the wall. I figure it’s doing the trick, new to co2 so will see how it goes. I just put the seedlings in this week.

Seedlings really don’t need CO2. ... I’m new to it as well in a 20x30, but I’d wait till they are good and rooted, and in thier final pot. Then introduce CO2 at like 600, and then in week 4 of veg, bring it up to 800. By the time you flip, be at 1200, and up to 1400 in weeks 3-6 in flower, then start tapering off in weeks 7-8 back down to atmospheric around 400 at finish. I’m new to it as well, but have gotten some great advise on the matter.

Most fans do not have powerful enough motors to cut through a finger, spin fast but stop easy.

Can you not try a carrot at least, easy to clean up?
