Can't remember seeing an intake fan?
There was no fresh air in I used CO² and A/C. The plant makes itâ??s own Oxygen as a by-product of the chlorophyll process. You have the blower that was the air in on the lights you are using. The exhaust side was pumped out the roof through a vent pipe. You have my blower box how is that working for you now dog?

There were one blower for the lights and one mounted in the ceiling to exchange and scrub the air. It ran all the time 24/7 and scrubbed the air and returned it to the room. When I needed to exhaust the CO² there were dampers on the roof that switched between air return and air out. The carbon scrubber was in the ceiling so odor was not a problem.
