Passive intake position

[Paqnampiza]

Hello,

I have a quick question,

I'm growing in a cabinet and have all my ventilation design planned out but I was wondering if the position of the passive intake matters much.
Having it opposite the exhaust is the best position correct?
What about the height placement in regards to the plants, is it okay to be blowing directly onto the plants?

it will be fine unless the ambient temp is very low?
also consider blynx's way of inlets in the floor.
search this grower out. he (and many others) have their vent inlets in the floor and it works perfect.

good luck with your cab design.
and be a happy grower!

peace
