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?

yes you can blow air on your plants as long as they are not flapping in the wind. the ideal venting set up would be your exhaust hole is up high so that it pullls out hot air and your intake hole is low so that it sucks in colder air

I'm with ogtommy. I put my discharge duct high and intake duct low. Sucks cool, blows hot.

Thanks for the input guys, eased my mind on the subject.

Your intake is to exchange air in the room and provide fresh air and CO2. Put it at the bottom opposite the exhaust.

Use regular fans to circulate air within the room.
