atm i just keep the tent doors open so im guessing i dont need to extract air? im sorry if anyone missunderstood, i dont use any of the 2 fans for extraction atm, im drawing air FROM the window to the tent. im going to ofc use a carbon filter (?) and extract air from the top but atm its seedlings only 5-6 days old so no need for filtering anything cus of no smell.. but still the room is heating up and i need to keep the door open but ofc.. thats not an option in the long run..

i'd buy a cooltube if i had money
i'd have money if i had a job


lolz just kidding *emo* but ya rly ill try to save up some cash (somehow) and buy a cooltube..

OH almost forgot! if i buy a cooltube do i seriously need a NEW fan?? omg thats an extra 100$!!

atm i got one 125ø fan and one 100ø. i use the 125 for the carbon filter and extraction and use the 100 to blow air in to the tent.. do i need another one for the cooltube?
