My flower room is 18ft by 12ft. I’m guna have 2300 watts of LED lights running over 5 lights and 60 plants. I already have a 12inch extraction fan running through the ceiling. There is a window in there which I have boarded up and then just a door with the crack round the edge, so the room is some what semi sealed. But obviously air can still get in through the door etc, so is having oscillating fans and the exhaust fan going enough to pull new air in? How important is it tj have an intake fan in regards to fresh air and c02 being brought in?

cool, i was working on the assumption that there was space to intake air around the grow area. i saw the measurments, but after re reading it, i can now see that its a dedicated room.
a ocelating fan woun't pull air in much if at all. the intake fan could be changed up for a more powerfull one to draw more air in from doorway.
i would drill some holes in the boarded up window. open said window, get some fine mesh cloth to cover it with, increacing the amount of quality air into the room

you can indeed build a sealed room with the ability to vent. can use dampers on a spring or electric ones that will open when the fan kicks on. the room i did has a natural gas co2 burner when the lights kick off a timer kicks on a fan and a damper opens and it exchanges all the air in the room then when thats finished the fan turns off and the damper closes until the next time the lights kick off. however what your describing doesnt sound like a sealed room.

A 12 inline fan will suck air thur any crack it can find just leave the door cracked dont need a intake fan. 2300 watts is very small for a 18 by 12
