I'm currently flowering in a 3x2x4.5 tent. I'm looking to add a 2x2x2 tent to veg some small plants while flowering then to hang my harvest once done in the bigger tent to dry.

What kind of filter/fan setup should I use in the 2x2x2 that won't take up much space?

By blowing into do you mean attached with some kind of ducting? I thought the fan pulled air through the filter? Not blown into it.

Sorry if this is a dumb question. I'm still very new to all of this.

yeah I'm suggesting to do exactly that, u will have to use a ton of tape and possibly a box to get the square pc fan to connect with the round filter

I do not recommend what he is suggesting. Carbon filters are built to have air sucked through them, now blown through, and a pc fan will not be powerful enough to blow nor suck air through a carbon filter.

There are formulas for all of this though. I only know the metric ones, but google your way to a cfm calculator and find a filter that supports the cfm of the fan.

In that small of a tent would just having a small desk fan blowing throughout with some filter pads over the vents suffice?

hi from australia, im in the process of mapping my own little 2.5ft x 4.5ft x ?? cab
ive searched for different ways to get this done and i believe just opting for a 100mm fan and a 100mm, 4inch x 12 inch carbon filter will be the go maybe for your case as you have a cube it might be better to run the filter / fan / ducting on the roof of the tent and cover it up somehow so it just sucks out?

im a little fucked myself because i cant find a nice 100mm centrifugal fan with speed dials from australia, (240v)

another idea is to get a 3 or 4 pin step down to USB, picking an 80mm fan and just running it on a usb adaptor off a powerboard for fan, not sure what to do for carbon scrubbing in this case though.
the idea for running an 80mm fan is because it runs on 5v rather then 12v, as most fans over 80mm run on the 12v rail, an 80mm fan will run full capacity on those links.

for the pc fan route,

and a nice little chrome grill if you are running a wooden box :)
