Temp issue, my garden is struggling!

Hi guys.

I have 10 bagseed growing and recently repotted too 10 litre containers and growth accelerated at a crazy speed. They are now covering such a big area i had too turn on my second 400w mh.

This makes my temps go way up there in 32 celcius after only 3-4 hours of "daytime".

I have a 184 m3/h inline fan placed inside my growroom pushing air up the attic and then 7-8 meter along the roof up there before exiting the house..

So thars maybe 10 meter ducting from fan and out.

Is it the distance thats making it ineffective or the fact that im pushing instead of sucking?

Long post but vital info

thank you

its easyer to pull are than push

So you mean my effective cfm will be higher if i run 8 meter ducting from growroom to the fan and then outside?

ok ive redone the exhaust. now the fan is in the attic and 8 meters of ducting from fan too growroom. just by changing from pushing the air( fan inside growroom) too pulling from the attic my temps are now stable at 24-25 celcius instead of 31-32

in other words.. pushing air is bullshit

happy to help always remember pulling air is easier than pushing and you temps are in perfect range as well
