And no this is nothing to do with any sexual references.
Ok building a grow room and have been looking at extraction fans what air movement ..... etc
Passive intake has got me confused, i have a small grow room 4ft x 5ft x 5.5ft and use a 8inch extraction fan but my passive intake is only 6inch.
The confusion is nearly every post of advice i have read is saying i should have a hole 3 times as big as my extraction or have more than 1 intake hole ?
The reason i made my hole smaller was to create a negative air pressure to suck out my stale air and it works so im confused.
Unless i experiment and make another hole to compare im not sure on the design of the bigger grow room.
If anyone who has experience on passive intakes i would be interested because im not sure by making the intake hole much bigger than the extracted one how can it efficiently exchange the air ?
Please educated me on this matter before i have to
a. make more or bigger intake holes
b. go round filling them in
