so i scrounged together some money and was able to get some ducting and a 4'' inline fan ..i grow in a tent that has tons of velcrow flaps for intake and outtake...so since i only got the one fan my question is should i open up all the upper flaps and suck in new air through the bottom intake??or open up all the flaps and suck old air out from the top?? any input is appreciated rep+
