my tent 40cm x 40xcm x160cm had at bottom left 12cm hole and in top 12cm hole... i press 15cm tube in....15 is very big or not? in my growshop he mean 10cm was enough and 10cm axial 100qubik h i do 15cm axial with 275qubik h and 15cm tube...and i had 15cm intake in the small tent the walls go together 2. now you say wrong axial but a little op axial is better!You don't understand, both my post, and proper ventilation. I never once said he should get a fan. He needs a bigger intake, I did not say buy an axial fan.
I've no doubt this explanation will be lost in translation but seeing as you called me out, I'll school you
when you see the tent walls suck in like that it is because there is negative pressure, which means their is insufficient intake to meet the needs of the exhaust, this restricts the exhaust, of course it will, the intake becomes the limiting factor, the exhaust can only move as much air as the intake will allow though it, therefor slowing the movement of air through the tent thus making the whole system less efficient.
With a bigger INTAKE (I didn't say intake fan) you lower the restriction, more air is pulled through the intake, allowing the exhaust to move more air out of the tent. The result of this will be more efficient use of the equipment to control the environment, and it will also solve his problem of the walls sucking inward so much that he's losing valuable canopy space.
in your theorie i need 40cm intake or 100cm ???
thank you for teaching me
