How much m3/h extraction will I need

My tent it 1.2m x 2.4m x 2m
That’s 5.76 cubic feet I believe
Cfm is 203 ?
Help lol

That’s roughly a 4x8 ft tent 6 ft tall I think. That’s 192 cubic ft . If you add filters and or hard bends you want higher cfm rating

Entirely depends on your ambient temps.

Hot climate needs more air exchange to maintain ideal range

That was backwards you need 326 m3/h or more

Also depends on lighting choice.

length of duct runs to exhaust away from the grow area.

carbon filter attached or not

bends in the ducting.

too vague to give an exact answer as it’s not just the tent that matters.

Nice to see you back and active @coreywebster

It's such a rabbit hole question ey!

Good to see ya fella!

Okay thank you all ! I worked it out I’ll need 346 m3/h minimum so I’ll go for a 400m3/h rhino extraction and a 280 m3/h intake

I’m using led one side (625 actual watts)
And a 600 watt hps the other side

temps currently stay around 26 degrees Celsius
This is using a 280m3/h extraction and a 178m3/h intake but I have positive pressure.

honestly thank you all for your advice.

What's the LED your using Sam ?

I got viparspectra XS4000
Mars sp150
Viparspectra p600

the viparspectra XS4000 alone yielded me 556g on my last harvest so adding the extra to “fill in the sides”

Nice 1 man!
I have a lot of LEDs myself and the same size flower tent.
