Just letting u all know my tent has 3 holes

My tent has 3 holes, lol. Otherwise it is nice and i love it. Its 4x6.5 budboxx. I wanna put the light one indepent venting cirsuit but that takes 2 holes. The other hole is an intake. I thinking of just screwing on a flange kit and then cutting a hole in the midde, but i sure hate just to rashy screw my tent up. Does the smell you think stay up or down. Should a carbon filter be high or low? Any ideas. I' guessing hi, but any experience. I just bored really, just got some northern lights seeds ordered with some free seeds.

Carbon filters should be placed high, just like an out take fan.

The reason for this is that hot air rises and it seems logical to vent to hot air at the best point in the grow space, right?

So naturally the "smell" will circulate as the air rises and falls as it cools..

That thread has loads of DIY carbon scrubbers, in case you want to not spend loads of money on one.

Hope this helps.
