Ventilation

[e_farmer]

Hello every one

I want to design a stealth a growroom and i need some info about ventilation.
i plan to install one or two 17cm fan but i need some info about advanced stuff like backpressure etc,In order to become able to purchase the right fan for my needs.
My total air volume in the growroom including everythng is something less than 0.63 cubic Meters

I never had problems with heat but noise was not an issue.
Now i have big length input and exhaust, air cooled reflector and a carbon filter for odor control, so i have to go advanced

Any info is welcome
Thank u people

I like your name dude. However, less than 1 cubic meter, is not a room, it is a box or chamber. Take a look at the grow diaries, and micro grows to get an idea of what other folks do, then adapt that to your size needs, good luck, and have fun.

ok i will call it growspace so we can be both happy
but i need some info like.... what if i gave a lot of 180 degree turns on my vent system? what is needed to be done so i can have a descent airflow
cfm is not the only spec written on fans/blowers

That is why I recommended you read the grow diaries and threads, you can find similar size grow spaces, see how they exhaust/ vent, and maybe ask a question or two from someone who is tuned in to your specs already. To me, 17cfm is about what I blow out when I exhale from a bong hit, not a fan, so I thought you would find help in the micro grows.
