So ur tent is 4.8m3 same as mine, I run a 5 inch centrifugal exhaust 350cfm and a 4 inch intake that offhand I think is 280. You lose 5% per meter of ducting and each 90degree bend, and 20% on the filter you want your tent to empty once every 2 mins I think the recommended rate is. So it's just a case of maths to work out how often it will clear your tent. Just remember you want negative pressure or you will get leaks, I just use fan controllers until I get the temp and flow rightWhich one do you recommend if I were to upgrade to 200x200x200 tent, fan and filter? I'm stupid at this CFM shit etc lol.
Right now in the 120x120x200 I got a 6inch fan 'ram' with the filter that comes with it, its pretty big.. but we did notice smell was leaking, i think it may be due to high humidity.. we didn't have a dehumidifier but getting one for next grow
2x 240watt leds 'kingbrite' & a SF1000 from spiderfarmer next grow , 120x120x200 but looking to upgrade probably.
Cheers man I will do :)
